80s Returning Doctor
Chapter 29 "Professor Qiu is also willing to...
"Professor Qiu is also willing to give me a chance. If it were someone else, they might think that I am talking nonsense and just take those words as air." After all, He Jing was just a newcomer when he came in. Even if he has a doctorate, he just graduated , which seemed to them young and completely inexperienced.
Professor Han is also impressed, as a student, he has never been in vain in the past few years abroad.
"Is your research not going well recently? I heard that those in the material group have some opinions on your research?" This is the real reason why Professor Han came to He Jing.
He Jing smiled and waved his hand, "It's not going well, and it can't be said that there is an opinion? It's just that the ideas are not unified. The two of us think that the research direction is inconsistent. Maybe they think I am wasting materials and time. Delay the progress of the project."
Seeing that He Jing didn't care, Professor Han was relieved. He was afraid that the talents he had finally got back would be hit and ran away. After all, this was the first major research project.
"That's good. We who do research are not afraid of going in the wrong direction, let alone wasting time and materials. What we fear most is that we dare not try or think. Since you think you are right, then stick to it and use actions to convince us." other people."
Professor Han is here to support him. He Jing was a little surprised by this, and was a little moved in his heart. He nodded seriously, "Understood."
"But aren't you afraid that I'm wasting time and materials? I really spent a lot of money during this time." Otherwise, no one would have any objections to him. After all, in their view, He Jing's research is already considered abandoned.
Professor Han laughed, "I have spent more money on research than you have wasted over the years. Where are you now? Sometimes we may research until the end, ah, it turns out that the direction is wrong, save the capital. There is no way to save it, you, don’t worry so much. Why don’t you come to the conclusion quickly, maybe the truth is in the hands of a few people? And without you, the project team will waste more money.”
This is true. If there is no direction proposed by He Jing, they will need to spend a lot of time and money to find the main materials.
"Got it, I will."
"That's right, but don't be too stubborn. Set a point for yourself. If that day comes, and you feel that there is really no way out, then change the direction. It is also possible to give up decisively." After encouragement, of course It also needs to be reminded that Professor Han does not want to see He Jing go to a dead end.
He Jing nodded, "I understand this. I am very sure about the current direction. Now the main thing is to adjust the ratio. It is estimated that there will be preliminary results in a short time, and everything will be clear by then."
The direction is that direction, but He Jing needs to master all the craftsmanship and proportions. Fortunately, the original owner has also studied physics and materials, otherwise everything would not be so easy.
Hearing that Professor Han was happy, "That's good, that's good, I'll just wait to see your research results!"
The topic ended here, and after walking a few more steps, they arrived at a pavilion, and the street lamps on the side of the road gave off a warm yellow light.Professor Han took He Jing to sit there, the moonlight was just right, but it was a pity that there was no wine, so he couldn't learn how to drink with the moon phase like Brother Taibai.
Professor Han: "By the way, He Jing, which course do you plan to teach next semester? Or let's forget it for now, after all, you are quite busy with experiments."
Time passed quickly, it was only June when He Jing came back, but now it is already August, and it will be September in more than ten days, and the school will start soon.
He Jing really didn't bother to think about this issue, it should be said that he had already forgotten about this matter.
After thinking about it, "Don't cancel it, it should be fine to take a class once a week." Now that he has agreed, He Jing doesn't intend to make a mistake, and he was a lecturer before, so he already has experience, so he is not very worried .
"Alright, then have you thought about which course to teach? It's better to take an elective course, which will be easier." Professor Han originally wanted He Jing to take on some teaching tasks, and he was very happy with He Jing's choice .And he also has another purpose, which is to set an example.Now many students do not come back after studying abroad, which is not good for Huaguo, but He Jing chose to return to China to build the motherland. He hopes that the students in the school can learn like him.
"Then take elective courses!" But he was a little embarrassed to choose what to teach. He used to teach basic physics, but now it seems that this is not possible.
Professor Han pondered for a while, then suddenly thought of one, and immediately said eagerly: "It's better to teach high-energy physics! How about "Experimental Methods of Nuclear Physics and Particle Physics"?"
"This?" He Jing didn't expect it to be this course, which is more practical.
"That's right, our students have poor hands-on skills. You happen to be more professional in this area and know a lot. You can pass on your experience."
"Of course." Of course He Jing has no objection, this course is theory plus practice, and lesson preparation is not that troublesome.This course is usually offered in the third year of junior year. At this stage, everyone has a certain foundation, so it is easier to teach, and it is an elective course, so it is not so tiring.
"Then it's settled. I'll arrange it for you directly. If the time is Tuesday afternoon, you can talk to Professor Qiu when the time comes, and try to free up this time."
Since He Jing had no problem, Professor Han gave He Jing a direct decision.
After finishing what he needed to say, Professor Han stood up and patted his wrinkled trouser legs, "Okay, it's getting late, you should hurry over and rest, remember to be safe."
He Jing nodded in agreement, watched Professor Han leave, and then left himself.
A few days later, before He Jing's preliminary results came out, the NbZr alloy made great progress, and the first alloy was synthesized. Although it was only a very rough alloy, its various properties were very poor, and it was far from what the accelerator needed. There is a big gap between the finished products, but this also inspires everyone in the laboratory, as if hope is in sight.
Of course, this does not include He Jing, after all, he insists on another direction.And with this initial success, the pressure on He Jing has also increased.There are more and more direct people who want He Jing to give up his research. Even Professor Lan came to He Jing.Although he didn't directly ask He Jing to give up, He Jing also understood what he meant and wanted He Jing to give up.After all, NbZr alloys have already had successful precedents, and there is no need to look for another direction. They have limited manpower and need to be optimized quickly.
He Jing was also very helpless, a little dazed, knowing that he was right, but he couldn't give a reason.He can't tell these people directly that NbZr alloys will be eliminated in the future, so they will probably be sent to a mental hospital.
After one successful experience, it seemed to be a matter of course. They mastered the method, and the quality of the alloy was gradually optimized, reaching the standard of low-temperature superconductivity step by step, and the resistance became smaller and smaller. Not far away.All eyes are on the synthesis of NbZr alloy, and He Jing's research has been considered useless by everyone.
Another day passed, and today they produced an alloy material that could initially meet the needs of the accelerator for the first time. Everyone was very excited, and several people in the laboratory planned to celebrate.Of course, this is a celebration between colleagues, not including Professor Lan.
He Jing intends to continue to stay in the laboratory. He is under a lot of pressure now, and has worked overtime for many consecutive nights. These days, his family can hardly see him, and they are also very worried.But He Jing knew that his time was limited.
At this time, the experiment in his hands had reached the final step, and the finished product was in front of his eyes. This was the first time he had synthesized a compound that was closest to the state of later life. He was very excited, but the expression on his face became more and more condensed.We have reached the last step, whether we can succeed or not depends on this for a while.
Several people packed up their things and looked at He Jing's position. Among them, Feng Tinghe, the oldest, thought it would be better to call He Jing, after all, he could be regarded as a part of them at present, and such activities were not easy to ignore. He is alone.
"He Jing, let's go out to get together, why don't you go with us?"
He Jing paid attention to the instrument in front of him, but after turning around for a short while, he concentrated on his work again, "No need, the experiment in my hand still needs a lot of time, and this time is inseparable." The alloy manufacturing process is very troublesome , It also involves some dangerous operations, such as crushing, sintering, heating fusion, pressing, etc., which require great concentration.And the result will appear soon, and he doesn't want to miss it.
Feng Tinghe nodded and didn't say anything. He had already expected that He Jing would say that. After all, he had only reached the first step in this experiment, and it would take a long time.
It's just that if he doesn't speak, others don't necessarily.
"Hey, I said, what's the point of your experiment, or give up, our project is almost successful."
"Yeah, it's a meaningless thing at all!"
"Hey, why not help us if you have time."
Feng Tinghe frowned, looked at He Jing, and saw that he seemed to relax a little without much reaction, but he quickly stopped them from continuing, "What are you talking about! Hurry up, leave."
"We're not wrong!" A few people muttered, but they didn't feel that there was anything wrong with what they said. After all, this is the truth. They are not the kind of people who play tricks and say what they have. The scene is in vain.
Feng Tinghe waved his hand. He is older and has experienced more things, so his temperament is more tolerant. Even if he thinks the same as them, but these words are not pleasant to say, wave his hand to make people go out quickly.
The few people didn't care about being kicked out, since Feng Tinghe refused to let them speak, they all went out with their things.
Feng Tinghe didn't leave right away, he walked up to He Jing after everyone else went out, "Xiao He, don't pay attention to what they say, they don't have bad intentions, they are just anxious to study, so they talk Just hurry up."
He Jing really didn't care, that's where it is. These people who are engaged in scientific research, even if they accuse them, they are very plain and simple. How can there be so many tricks in later generations? He Jing is someone who has seen the power of public opinion.He glanced at the instrument, and estimated that it would be completed in a short time. He didn't need to perform any operations at this time, so he was in the mood to chat with the other party.He flicked his long hair, thinking that he should cut it, but he raised his head and smiled nonchalantly at Feng Tinghe.
"It's okay, I don't care, and I understand what they think."
Feng Tinghe smiled reassuringly, and then asked hesitantly: "He Jing, where is your current progress? Do you have any preliminary research results, or materials that can prove that your idea is correct?"
He Jing glanced at him in surprise. He didn't expect him to mention this. After all, these days everyone seems to think that He Jing's experiment is hopeless, and most of them just persuade He Jing to give up. No one pays attention to He Jing's ongoing experiment. Experiment above.
Seemingly understanding He Jing's thoughts, Feng Tinghe touched his head with a smile, and said a little embarrassedly: "I always feel that science has no absolute truth, and sometimes we feel that a direction is not good, maybe because we don't understand it. I know enough, so I arbitrarily say no.”
"Just like now, because the Zr element is easier for us to understand and use, we all think that this is the most suitable element, and for the Ti element, because it is difficult to deal with, we don't know enough, so we say no. This is not The representative is correct, so I just wanted to ask, did you find anything, or evidence..."
Feng Tinghe did not say anything behind, that is, "Otherwise, why do you persist so much? People will never persist in things that will definitely fail, unless they are stupid. But He Jing is not stupid, he is very smart on the contrary."
He Jing raised his eyebrows, but he didn't expect that Researcher Feng, who looked like a good old man and was conservative in everything, could see it so clearly.
"Aren't you afraid that my brain just went to a dead end, the kind that goes all the way to the end?"
Feng Tinghe laughed, as if he thought He Jing's words were funny, "How can someone who can study abroad but choose to return to China have such a personality? I think you can still afford to let it go."
He Jing couldn't help but feel a little more relaxed. It's rare for someone to understand him, of course Professor Han is not counted. They are masters and students, and they understand each other better.But Fengtinghe is different, they don't have many opportunities to deal with each other.
"I can only be sure that the Ti element is the most suitable for the Nb element. As for the evidence..." He Jing spread his hands, it will take time.
Feng Tinghe was puzzled, "Why are you so sure? You must know that the density and melting point of Nb and Ti elements are very different, and it is very difficult to combine them together. There are always Nb non-melting blocks and Ti, and the composition distribution is not uniform. Especially Ti The activity is very high, and the purification is very difficult. This is why we quickly eliminated the Ti element."
What can He Jing do? It’s rare for someone to listen to him, so let’s explain it well, “Ti is a microalloying element that can increase the critical point, and its strength, toughness and weldability are more suitable than Zr. And both Ti and Nb are stronger than Zr. Elements that form carbides, when cooled, their solubility decreases, and carbon and nitrides will be precipitated..."
Feng Tinghe shook his head, "You are right, but based on the current alloy research, it is easier to use Zr."
He Jingxiao, "Indeed, at first glance, it is true that Zr is better and easier to manufacture. Maybe the process is not so troublesome, but can this guarantee performance? What we need is to research better accelerators, so the material I still insist that I can continue to study in depth, even if it takes a little longer."
Of course, He Jing knows that the project can be completed by using the Zr element, and it can be better, but he knows that there are better ones, so how can he tolerate the not so good one?And in the near future, NbTi will eventually become the trend. He doesn't want Huaguo to continue to lag behind. Maybe he is too demanding, but he doesn't want to give up persistence.
"But we've had enough."
He Jing immediately retorted, "It's just enough, not better."
"It not only takes time, but also funds. We don't have that much time to bet on an impossibility!"
"But every research we do is actually a gamble, isn't it? Especially in the field of material research, we are always betting on a possibility and luck. No, it shouldn't be said that, it should be ruling out the impossible Looking for possibilities. We have not completely ruled out the Ti element now, and there are still many possibilities in it!"
"But we don't have time."
"But I think I'll be able to touch that path pretty soon." After all, he's been on the right track all along.
"Are you so sure?" Suddenly a voice came, it seemed that these bigwigs liked to appear suddenly like this, and it was at an inappropriate time.
The two people in the room looked in the direction of the door. It was Professor Lan standing at the door with a briefcase in his hand. He didn't know if he was about to leave or just came back.He should have arrived not long ago, and there was still some sweat on his face.
"Professor Lan." The two greeted him one after another.
Professor Lan waved his hand indifferently, walked in, and asked the question just now, "He Jing, why are you so sure?"
He Jing nodded seriously and did not evade, "That's right, I'm sure, I have now found a way to melt the two and make them fully and evenly formed. At present, I have a preliminary finished product, but the quality is very average. It’s a constant adjustment.”
"Really? Where? Let me take a look?" Professor Lan was also a little surprised, his eyes wandering around the workbench that He Jing used before for self-study.
"This." He Jing took out a piece of silver metal product from the workbench. It was still a little rough, and there were some bumps on it, obviously it hadn't been carefully polished and processed, but the color was quite bright, and it looked as a whole. Very nice and fairly even.
"Is this really an NbTi composite?" Professor Lan looked at this small piece of synthetic metal carefully, with some doubts in his tone. What they made before was very different from this one, so it's no wonder he was so suspicious.
He Jingjing nodded. This is a not-so-failure finished product after so many failures, and it can barely be regarded as a finished product.
"What method did you use?" Professor Lan was very curious. Even if it is determined that this alloy does not have the effect they imagined, understanding the synthesis method will also be of great help in the development of other materials in the future.
"I have experimented with many methods. At the beginning, I carried out alternate lamination melting. Although it is simple and cost-effective, it is a pity that the distribution of the alloy is extremely uneven and the quality is extremely poor. It can be said that it is difficult to use. Afterwards, I referred to Atil powder smelting method, but it is too difficult to extract high-purity Ti and Nb powder, and it is difficult to meet the technology and funds. And the smelting process will lead to the inhalation of other particles. Later I improved the method, Create a vacuum environment...."
"The cost of the alloy produced in this way is relatively low, and it is not easy to have impurities, but the specific ratio has not yet been released..."
This is the first time that He Jing has extracted finished products. Previously, due to various reasons, the products he obtained were all inexplicable failures. Although the superconducting performance has not been tested yet, He Jing knows that victory is not far away.
"Wow, that's a very good idea, but you should have told me earlier that you have already made a finished product." Professor Lan was a little excited, but also somewhat dissatisfied.
"I just made it for the first time in the afternoon, and it's not really a finished product yet."
"Have you done the test?" Professor Lan was a little impatient. He had a feeling that a major change was coming, which made him a little impatient.
He Jing shook his head, "I plan to make a few more for comparative testing, to find out the most suitable ratio and catalytic method, this one is not enough for testing."
Professor Lan put the finished product away, threw the briefcase on an empty table at one side, rolled up his sleeves, and walked to He Jing, "I'll help you, we'll make enough finished products as soon as possible, after that carry out testing."
He Jingjing nodded, and naturally he would not refuse. He also finished the experiment earlier, so that his arguments would be more.
Feng Tinghe on one side was still a little dazed, wasn't he still asking questions just now, why are they going to start doing it now, and have they forgotten, there is still such a person standing here!His size is also one hundred and two hundred catties, which can also be ignored.
"Cough, cough, cough..." After waiting for a while, alas, let me remind you by coughing twice.
Hearing the sound, He Jing looked over, feeling a little strange, "Hey, Feng Gong, you haven't left yet? Didn't you say you're going to have dinner together?" No wonder he said that, He Jing was all focused on Professor Lan just now, and he really was going to This one was forgotten, and he didn't make a sound, so He Jing thought he had already left.
Feng Tinghe was even more speechless, he just left, "I..."
It's a pity that before he finished speaking, Professor Lan chased people away, "Let's go, let's go, what should we do, don't waste our time here!"
This is definitely because he disliked himself and got in the way, but he didn't want to leave like this, and asked politely, "Professor, He Jing, otherwise I will help you, maybe it will be faster." In fact, he There is still some hesitation in my heart. On the one hand, there is a party that has been promised, and it is not easy to break my promise.On one side are the leaders and colleagues who are working overtime. It's okay if the others don't meet, but he is here at this time, so he can't just leave and go to the dinner party. Isn't that not good.
At this moment, he didn't know whether to regret or be glad that he stayed for such a while. He regretted that it was a bit embarrassing to leave the country, but he was glad that he knew something that he shouldn't have known so early.
Professor Lan didn't know what was on his mind, so he just waved his hand impatiently, "Let's go, we don't need your help, what should we do?"
"Okay!" In the end, Feng Tinghe could only accept it, sighed with some regret, and left with some reluctance.He still wants to see how the following experiments are going, especially the test results, otherwise he will come back after the dinner party is over.
An hour later Feng Tinghe came back, his face and body were covered with sweat, obviously he ran back, he was really thinking about the experiment, he ran back to help after a hasty meal.Professor Qiu didn't say anything when he saw him, and waved his hand to ask someone to come up to help.
After a whole night of non-stop experiments, they produced several more pieces of alloy at three o'clock in the middle of the night. This time, the quality of the finished product was much better than what they had seen before.After that is to conduct a number of performance tests.After all, Professor Lan was old, and the test took a long time. He Jing strongly urged him to take a rest. The two young men could just look at the test results.
Professor Lan didn't agree at first, but after a while he became dizzy and yawned continuously. He had no choice but to give in, but he didn't leave, he just went back to the office and lay down. Tell him, as soon as the result comes out, notify him immediately.He Jing had no choice but to nod.
In the early morning, the sun rose, and the dazzling light pierced into the room. With a click, the light bulb in the room was turned off. He Jing rubbed his very tired eyes, holding the latest test results in his hand.Feng Tinghe, who had been waiting beside him, had already fallen asleep on the table.At this time, thunderous snoring resounded in the room, he opened his mouth slightly, and from time to time there was the sound of grinding his teeth, which made He Jing a little unbearable.
He rubbed his temples, and was about to call for someone, but he was probably too tired, and accidentally bumped into a stool, which fell to the ground with a loud noise.
Feng Tinghe was startled, his eyes hadn't opened yet, but he had already raised his head, looking at the place where the sound came from, with a daze on his face, "What's the matter? What's the matter?"
"What's wrong? It's already dawn!" He Jing was speechless. This man insisted that he would stay with him and help him, but it didn't take long before he fell asleep on the table. This elder brother is snoring, but snoring is not counted, and he still grinds his teeth.This night was really uncomfortable, that is, He Jing knew the law and did not break the law, otherwise he would really have to beat him out.
"Ah, so fast?" Feng Tinghe finally came back to his senses, opened his eyes at this time, touched his mouth quickly, and looked at the table he was lying on before, afraid that he would be ashamed to drool.He was a little embarrassed. He wanted to help, but he actually fell asleep.
He Jing ignored him, just packed up the materials and prepared to show them to Professor Lan.
Feng Tinghe approached He Jing cautiously, "He Jing, did the result come out?"
"Come out." Although he felt a little uncomfortable mentally, He Jing also knew that Feng Tinghe didn't do it on purpose, it was because of his body, so his tone softened a bit.
"Really! What's the result?" Feng Tinghe immediately became excited, he couldn't help rubbing his hands, and looked at the information in He Jing's hand.
"Look." Sensing the other party's gaze, He Jing paused for a moment, then handed the information to the other party.
Without hesitation, Feng Tinghe took it over and looked at it immediately. He was very fast, skimming some unimportant data in his opinion. The most important thing is to pay attention to the critical temperature, performance and other aspects.
As time passed, the expression on Feng Tinghe's face gradually became excited, and the hand holding the document couldn't help shaking, which showed that his heart was not calm.
"Is this data true?" He Jing asked with some disbelief.
He Jing raised his eyebrows, "Of course, or you can try again."
"Test No. [-] has the best quality, the most uniform distribution of elements, and the best performance."
"But this result is too good." Feng Tinghe still couldn't believe it. Even though he participated in the production of the finished product, he watched most of the test from the sidelines, but the data is simply against the sky. Compared with this developed alloy, it is simply a world of difference.
"I'm sure that the result is fine, and this is just the beginning. We can continue to improve the process and process later, and the data will be better by then." He Jing was very confident, patted the other party on the shoulder, He conveniently took away the information in his hand.
"If you still can't believe it, then try it again. The finished product happens to be here, so I'll go to Professor Lan first and tell him the result."
Feng Tinghe shook his head and followed He Jing, "That's no need, I'll go with you to find Professor Lan." Of course he believed in He Jing, and he also knew that there was no need to retest, after all, such a test would have to be done later. There are many times.
"Okay, let's clean up this thing first." The important thing is the experimental sample.
The two worked together, and soon He Jing and the others restored the laboratory to its original state, put the finished experiment into a box, and the two returned to the office with the things.
It was still very early, the office was facing a different direction from the laboratory, and there was no sunlight coming in. It was still dark and quiet inside.
The two stepped into the door, Professor Lan seemed to feel it, and sat up straight. His hair was still meticulous, and there was no trace of sleepiness on his face, as if he had never fallen asleep at all.
Seeing He Jing and the others, Professor Lan was very anxious, "How is it? The result is out?"
He Jing walked over and handed him the information, "It's out, the data is here."
Professor Lan took it, and he couldn't wait to roll over his numb legs and hands.As he watched, his eyes became brighter and brighter. When he saw the most important data, he couldn't help swallowing. In the end, he slammed his hand on the table, "Okay, okay... ...."
After closing the document, Professor Lan fixedly looked at He Jing, "Okay! He Jing, I did not misread you!" Everyone felt that He Jing wasted time, and he gave He Jing time.Even though he felt a little hesitant later, he still didn't force He Jing to give up, otherwise how could he have the result today!
"?" Just when Professor Lan was excited, several people walked in together. It was a few researchers from the material group. They were full of doubts on their faces at this time. Excited.
"What's the matter? Did something good happen?"
"Feng Gong, why are you here so early?"
"Yes! What happened to Professor Lan?"
A few people walked to Fengtinghe, and it happened that Fengtinghe was some distance away from Professor Lan and the others, so they couldn't help asking, their voices were very low, but Professor Lan also noticed them.
"Hahaha, you guys came just in time, and I have good news for you." He was smiling all over his eyes, but he just said this, and then he watched everyone's reactions,
Professor Lan has a gentle personality and has always been easy to get along with. Outside of working hours, everyone gets along very casually. Immediately, someone asked curiously, "What's the good news? Could it be that the higher authorities have allocated more project funds to us? "
"Yes! Professor Lan, hurry up and tell me!"
"Professor Lan, when did you start buying Guan Zi?"
"Yes, yes!"
They were indeed very curious. Judging from Professor Lan's performance, it was enough to see the good news.
Professor Lan didn't hesitate much, and pointed to He Jing beside him, "This good news is brought by our Dr. He. He has researched NbTi alloy. After testing, this alloy is an excellent low-temperature superconducting material. Alloy The distribution is even and the performance is excellent."
The news is really good news. For their entire project team, having better materials is indeed very good news.But for those of them who insist on using the Zr element and disagree with He Jing's research, this news makes them a little embarrassed.Happiness, well, it doesn't seem to be much, it's more about the shame of being slapped in the face.
Especially Jiangnan Du, who had had a not-so-harmonious communication with He Jing before, his face flushed a little, and he looked at He Jing who didn't look at him at all, and couldn't help but confirm it to Professor Lan.
"Professor Lan, is it true? Can I have a look at the experimental data?"
He just made the request, and several other people responded one after another, "Yes, Professor Lan, let us take a look?" Why did it just pass in one night, the world seems to have changed, obviously they were so happy last night It's too hard to celebrate success together with others, only to be told today that their research was useless.
Professor Lan also roughly understood their thoughts and understood them very well, so he gave them the document without saying anything.
Several people watched together, the room was very quiet, no one disturbed them, and He Jing just stood quietly, with a very flat expression on his face, not proud, let alone leaking any bad emotions.
As time passed, they read many copies of this type of information, and soon found the key data, and all the luck on their faces disappeared.Several people looked at each other, although they didn't want to admit it, but the data told them that the properties of the alloy researched by He Jing were indeed stronger than theirs, much stronger.
Professor Han is also impressed, as a student, he has never been in vain in the past few years abroad.
"Is your research not going well recently? I heard that those in the material group have some opinions on your research?" This is the real reason why Professor Han came to He Jing.
He Jing smiled and waved his hand, "It's not going well, and it can't be said that there is an opinion? It's just that the ideas are not unified. The two of us think that the research direction is inconsistent. Maybe they think I am wasting materials and time. Delay the progress of the project."
Seeing that He Jing didn't care, Professor Han was relieved. He was afraid that the talents he had finally got back would be hit and ran away. After all, this was the first major research project.
"That's good. We who do research are not afraid of going in the wrong direction, let alone wasting time and materials. What we fear most is that we dare not try or think. Since you think you are right, then stick to it and use actions to convince us." other people."
Professor Han is here to support him. He Jing was a little surprised by this, and was a little moved in his heart. He nodded seriously, "Understood."
"But aren't you afraid that I'm wasting time and materials? I really spent a lot of money during this time." Otherwise, no one would have any objections to him. After all, in their view, He Jing's research is already considered abandoned.
Professor Han laughed, "I have spent more money on research than you have wasted over the years. Where are you now? Sometimes we may research until the end, ah, it turns out that the direction is wrong, save the capital. There is no way to save it, you, don’t worry so much. Why don’t you come to the conclusion quickly, maybe the truth is in the hands of a few people? And without you, the project team will waste more money.”
This is true. If there is no direction proposed by He Jing, they will need to spend a lot of time and money to find the main materials.
"Got it, I will."
"That's right, but don't be too stubborn. Set a point for yourself. If that day comes, and you feel that there is really no way out, then change the direction. It is also possible to give up decisively." After encouragement, of course It also needs to be reminded that Professor Han does not want to see He Jing go to a dead end.
He Jing nodded, "I understand this. I am very sure about the current direction. Now the main thing is to adjust the ratio. It is estimated that there will be preliminary results in a short time, and everything will be clear by then."
The direction is that direction, but He Jing needs to master all the craftsmanship and proportions. Fortunately, the original owner has also studied physics and materials, otherwise everything would not be so easy.
Hearing that Professor Han was happy, "That's good, that's good, I'll just wait to see your research results!"
The topic ended here, and after walking a few more steps, they arrived at a pavilion, and the street lamps on the side of the road gave off a warm yellow light.Professor Han took He Jing to sit there, the moonlight was just right, but it was a pity that there was no wine, so he couldn't learn how to drink with the moon phase like Brother Taibai.
Professor Han: "By the way, He Jing, which course do you plan to teach next semester? Or let's forget it for now, after all, you are quite busy with experiments."
Time passed quickly, it was only June when He Jing came back, but now it is already August, and it will be September in more than ten days, and the school will start soon.
He Jing really didn't bother to think about this issue, it should be said that he had already forgotten about this matter.
After thinking about it, "Don't cancel it, it should be fine to take a class once a week." Now that he has agreed, He Jing doesn't intend to make a mistake, and he was a lecturer before, so he already has experience, so he is not very worried .
"Alright, then have you thought about which course to teach? It's better to take an elective course, which will be easier." Professor Han originally wanted He Jing to take on some teaching tasks, and he was very happy with He Jing's choice .And he also has another purpose, which is to set an example.Now many students do not come back after studying abroad, which is not good for Huaguo, but He Jing chose to return to China to build the motherland. He hopes that the students in the school can learn like him.
"Then take elective courses!" But he was a little embarrassed to choose what to teach. He used to teach basic physics, but now it seems that this is not possible.
Professor Han pondered for a while, then suddenly thought of one, and immediately said eagerly: "It's better to teach high-energy physics! How about "Experimental Methods of Nuclear Physics and Particle Physics"?"
"This?" He Jing didn't expect it to be this course, which is more practical.
"That's right, our students have poor hands-on skills. You happen to be more professional in this area and know a lot. You can pass on your experience."
"Of course." Of course He Jing has no objection, this course is theory plus practice, and lesson preparation is not that troublesome.This course is usually offered in the third year of junior year. At this stage, everyone has a certain foundation, so it is easier to teach, and it is an elective course, so it is not so tiring.
"Then it's settled. I'll arrange it for you directly. If the time is Tuesday afternoon, you can talk to Professor Qiu when the time comes, and try to free up this time."
Since He Jing had no problem, Professor Han gave He Jing a direct decision.
After finishing what he needed to say, Professor Han stood up and patted his wrinkled trouser legs, "Okay, it's getting late, you should hurry over and rest, remember to be safe."
He Jing nodded in agreement, watched Professor Han leave, and then left himself.
A few days later, before He Jing's preliminary results came out, the NbZr alloy made great progress, and the first alloy was synthesized. Although it was only a very rough alloy, its various properties were very poor, and it was far from what the accelerator needed. There is a big gap between the finished products, but this also inspires everyone in the laboratory, as if hope is in sight.
Of course, this does not include He Jing, after all, he insists on another direction.And with this initial success, the pressure on He Jing has also increased.There are more and more direct people who want He Jing to give up his research. Even Professor Lan came to He Jing.Although he didn't directly ask He Jing to give up, He Jing also understood what he meant and wanted He Jing to give up.After all, NbZr alloys have already had successful precedents, and there is no need to look for another direction. They have limited manpower and need to be optimized quickly.
He Jing was also very helpless, a little dazed, knowing that he was right, but he couldn't give a reason.He can't tell these people directly that NbZr alloys will be eliminated in the future, so they will probably be sent to a mental hospital.
After one successful experience, it seemed to be a matter of course. They mastered the method, and the quality of the alloy was gradually optimized, reaching the standard of low-temperature superconductivity step by step, and the resistance became smaller and smaller. Not far away.All eyes are on the synthesis of NbZr alloy, and He Jing's research has been considered useless by everyone.
Another day passed, and today they produced an alloy material that could initially meet the needs of the accelerator for the first time. Everyone was very excited, and several people in the laboratory planned to celebrate.Of course, this is a celebration between colleagues, not including Professor Lan.
He Jing intends to continue to stay in the laboratory. He is under a lot of pressure now, and has worked overtime for many consecutive nights. These days, his family can hardly see him, and they are also very worried.But He Jing knew that his time was limited.
At this time, the experiment in his hands had reached the final step, and the finished product was in front of his eyes. This was the first time he had synthesized a compound that was closest to the state of later life. He was very excited, but the expression on his face became more and more condensed.We have reached the last step, whether we can succeed or not depends on this for a while.
Several people packed up their things and looked at He Jing's position. Among them, Feng Tinghe, the oldest, thought it would be better to call He Jing, after all, he could be regarded as a part of them at present, and such activities were not easy to ignore. He is alone.
"He Jing, let's go out to get together, why don't you go with us?"
He Jing paid attention to the instrument in front of him, but after turning around for a short while, he concentrated on his work again, "No need, the experiment in my hand still needs a lot of time, and this time is inseparable." The alloy manufacturing process is very troublesome , It also involves some dangerous operations, such as crushing, sintering, heating fusion, pressing, etc., which require great concentration.And the result will appear soon, and he doesn't want to miss it.
Feng Tinghe nodded and didn't say anything. He had already expected that He Jing would say that. After all, he had only reached the first step in this experiment, and it would take a long time.
It's just that if he doesn't speak, others don't necessarily.
"Hey, I said, what's the point of your experiment, or give up, our project is almost successful."
"Yeah, it's a meaningless thing at all!"
"Hey, why not help us if you have time."
Feng Tinghe frowned, looked at He Jing, and saw that he seemed to relax a little without much reaction, but he quickly stopped them from continuing, "What are you talking about! Hurry up, leave."
"We're not wrong!" A few people muttered, but they didn't feel that there was anything wrong with what they said. After all, this is the truth. They are not the kind of people who play tricks and say what they have. The scene is in vain.
Feng Tinghe waved his hand. He is older and has experienced more things, so his temperament is more tolerant. Even if he thinks the same as them, but these words are not pleasant to say, wave his hand to make people go out quickly.
The few people didn't care about being kicked out, since Feng Tinghe refused to let them speak, they all went out with their things.
Feng Tinghe didn't leave right away, he walked up to He Jing after everyone else went out, "Xiao He, don't pay attention to what they say, they don't have bad intentions, they are just anxious to study, so they talk Just hurry up."
He Jing really didn't care, that's where it is. These people who are engaged in scientific research, even if they accuse them, they are very plain and simple. How can there be so many tricks in later generations? He Jing is someone who has seen the power of public opinion.He glanced at the instrument, and estimated that it would be completed in a short time. He didn't need to perform any operations at this time, so he was in the mood to chat with the other party.He flicked his long hair, thinking that he should cut it, but he raised his head and smiled nonchalantly at Feng Tinghe.
"It's okay, I don't care, and I understand what they think."
Feng Tinghe smiled reassuringly, and then asked hesitantly: "He Jing, where is your current progress? Do you have any preliminary research results, or materials that can prove that your idea is correct?"
He Jing glanced at him in surprise. He didn't expect him to mention this. After all, these days everyone seems to think that He Jing's experiment is hopeless, and most of them just persuade He Jing to give up. No one pays attention to He Jing's ongoing experiment. Experiment above.
Seemingly understanding He Jing's thoughts, Feng Tinghe touched his head with a smile, and said a little embarrassedly: "I always feel that science has no absolute truth, and sometimes we feel that a direction is not good, maybe because we don't understand it. I know enough, so I arbitrarily say no.”
"Just like now, because the Zr element is easier for us to understand and use, we all think that this is the most suitable element, and for the Ti element, because it is difficult to deal with, we don't know enough, so we say no. This is not The representative is correct, so I just wanted to ask, did you find anything, or evidence..."
Feng Tinghe did not say anything behind, that is, "Otherwise, why do you persist so much? People will never persist in things that will definitely fail, unless they are stupid. But He Jing is not stupid, he is very smart on the contrary."
He Jing raised his eyebrows, but he didn't expect that Researcher Feng, who looked like a good old man and was conservative in everything, could see it so clearly.
"Aren't you afraid that my brain just went to a dead end, the kind that goes all the way to the end?"
Feng Tinghe laughed, as if he thought He Jing's words were funny, "How can someone who can study abroad but choose to return to China have such a personality? I think you can still afford to let it go."
He Jing couldn't help but feel a little more relaxed. It's rare for someone to understand him, of course Professor Han is not counted. They are masters and students, and they understand each other better.But Fengtinghe is different, they don't have many opportunities to deal with each other.
"I can only be sure that the Ti element is the most suitable for the Nb element. As for the evidence..." He Jing spread his hands, it will take time.
Feng Tinghe was puzzled, "Why are you so sure? You must know that the density and melting point of Nb and Ti elements are very different, and it is very difficult to combine them together. There are always Nb non-melting blocks and Ti, and the composition distribution is not uniform. Especially Ti The activity is very high, and the purification is very difficult. This is why we quickly eliminated the Ti element."
What can He Jing do? It’s rare for someone to listen to him, so let’s explain it well, “Ti is a microalloying element that can increase the critical point, and its strength, toughness and weldability are more suitable than Zr. And both Ti and Nb are stronger than Zr. Elements that form carbides, when cooled, their solubility decreases, and carbon and nitrides will be precipitated..."
Feng Tinghe shook his head, "You are right, but based on the current alloy research, it is easier to use Zr."
He Jingxiao, "Indeed, at first glance, it is true that Zr is better and easier to manufacture. Maybe the process is not so troublesome, but can this guarantee performance? What we need is to research better accelerators, so the material I still insist that I can continue to study in depth, even if it takes a little longer."
Of course, He Jing knows that the project can be completed by using the Zr element, and it can be better, but he knows that there are better ones, so how can he tolerate the not so good one?And in the near future, NbTi will eventually become the trend. He doesn't want Huaguo to continue to lag behind. Maybe he is too demanding, but he doesn't want to give up persistence.
"But we've had enough."
He Jing immediately retorted, "It's just enough, not better."
"It not only takes time, but also funds. We don't have that much time to bet on an impossibility!"
"But every research we do is actually a gamble, isn't it? Especially in the field of material research, we are always betting on a possibility and luck. No, it shouldn't be said that, it should be ruling out the impossible Looking for possibilities. We have not completely ruled out the Ti element now, and there are still many possibilities in it!"
"But we don't have time."
"But I think I'll be able to touch that path pretty soon." After all, he's been on the right track all along.
"Are you so sure?" Suddenly a voice came, it seemed that these bigwigs liked to appear suddenly like this, and it was at an inappropriate time.
The two people in the room looked in the direction of the door. It was Professor Lan standing at the door with a briefcase in his hand. He didn't know if he was about to leave or just came back.He should have arrived not long ago, and there was still some sweat on his face.
"Professor Lan." The two greeted him one after another.
Professor Lan waved his hand indifferently, walked in, and asked the question just now, "He Jing, why are you so sure?"
He Jing nodded seriously and did not evade, "That's right, I'm sure, I have now found a way to melt the two and make them fully and evenly formed. At present, I have a preliminary finished product, but the quality is very average. It’s a constant adjustment.”
"Really? Where? Let me take a look?" Professor Lan was also a little surprised, his eyes wandering around the workbench that He Jing used before for self-study.
"This." He Jing took out a piece of silver metal product from the workbench. It was still a little rough, and there were some bumps on it, obviously it hadn't been carefully polished and processed, but the color was quite bright, and it looked as a whole. Very nice and fairly even.
"Is this really an NbTi composite?" Professor Lan looked at this small piece of synthetic metal carefully, with some doubts in his tone. What they made before was very different from this one, so it's no wonder he was so suspicious.
He Jingjing nodded. This is a not-so-failure finished product after so many failures, and it can barely be regarded as a finished product.
"What method did you use?" Professor Lan was very curious. Even if it is determined that this alloy does not have the effect they imagined, understanding the synthesis method will also be of great help in the development of other materials in the future.
"I have experimented with many methods. At the beginning, I carried out alternate lamination melting. Although it is simple and cost-effective, it is a pity that the distribution of the alloy is extremely uneven and the quality is extremely poor. It can be said that it is difficult to use. Afterwards, I referred to Atil powder smelting method, but it is too difficult to extract high-purity Ti and Nb powder, and it is difficult to meet the technology and funds. And the smelting process will lead to the inhalation of other particles. Later I improved the method, Create a vacuum environment...."
"The cost of the alloy produced in this way is relatively low, and it is not easy to have impurities, but the specific ratio has not yet been released..."
This is the first time that He Jing has extracted finished products. Previously, due to various reasons, the products he obtained were all inexplicable failures. Although the superconducting performance has not been tested yet, He Jing knows that victory is not far away.
"Wow, that's a very good idea, but you should have told me earlier that you have already made a finished product." Professor Lan was a little excited, but also somewhat dissatisfied.
"I just made it for the first time in the afternoon, and it's not really a finished product yet."
"Have you done the test?" Professor Lan was a little impatient. He had a feeling that a major change was coming, which made him a little impatient.
He Jing shook his head, "I plan to make a few more for comparative testing, to find out the most suitable ratio and catalytic method, this one is not enough for testing."
Professor Lan put the finished product away, threw the briefcase on an empty table at one side, rolled up his sleeves, and walked to He Jing, "I'll help you, we'll make enough finished products as soon as possible, after that carry out testing."
He Jingjing nodded, and naturally he would not refuse. He also finished the experiment earlier, so that his arguments would be more.
Feng Tinghe on one side was still a little dazed, wasn't he still asking questions just now, why are they going to start doing it now, and have they forgotten, there is still such a person standing here!His size is also one hundred and two hundred catties, which can also be ignored.
"Cough, cough, cough..." After waiting for a while, alas, let me remind you by coughing twice.
Hearing the sound, He Jing looked over, feeling a little strange, "Hey, Feng Gong, you haven't left yet? Didn't you say you're going to have dinner together?" No wonder he said that, He Jing was all focused on Professor Lan just now, and he really was going to This one was forgotten, and he didn't make a sound, so He Jing thought he had already left.
Feng Tinghe was even more speechless, he just left, "I..."
It's a pity that before he finished speaking, Professor Lan chased people away, "Let's go, let's go, what should we do, don't waste our time here!"
This is definitely because he disliked himself and got in the way, but he didn't want to leave like this, and asked politely, "Professor, He Jing, otherwise I will help you, maybe it will be faster." In fact, he There is still some hesitation in my heart. On the one hand, there is a party that has been promised, and it is not easy to break my promise.On one side are the leaders and colleagues who are working overtime. It's okay if the others don't meet, but he is here at this time, so he can't just leave and go to the dinner party. Isn't that not good.
At this moment, he didn't know whether to regret or be glad that he stayed for such a while. He regretted that it was a bit embarrassing to leave the country, but he was glad that he knew something that he shouldn't have known so early.
Professor Lan didn't know what was on his mind, so he just waved his hand impatiently, "Let's go, we don't need your help, what should we do?"
"Okay!" In the end, Feng Tinghe could only accept it, sighed with some regret, and left with some reluctance.He still wants to see how the following experiments are going, especially the test results, otherwise he will come back after the dinner party is over.
An hour later Feng Tinghe came back, his face and body were covered with sweat, obviously he ran back, he was really thinking about the experiment, he ran back to help after a hasty meal.Professor Qiu didn't say anything when he saw him, and waved his hand to ask someone to come up to help.
After a whole night of non-stop experiments, they produced several more pieces of alloy at three o'clock in the middle of the night. This time, the quality of the finished product was much better than what they had seen before.After that is to conduct a number of performance tests.After all, Professor Lan was old, and the test took a long time. He Jing strongly urged him to take a rest. The two young men could just look at the test results.
Professor Lan didn't agree at first, but after a while he became dizzy and yawned continuously. He had no choice but to give in, but he didn't leave, he just went back to the office and lay down. Tell him, as soon as the result comes out, notify him immediately.He Jing had no choice but to nod.
In the early morning, the sun rose, and the dazzling light pierced into the room. With a click, the light bulb in the room was turned off. He Jing rubbed his very tired eyes, holding the latest test results in his hand.Feng Tinghe, who had been waiting beside him, had already fallen asleep on the table.At this time, thunderous snoring resounded in the room, he opened his mouth slightly, and from time to time there was the sound of grinding his teeth, which made He Jing a little unbearable.
He rubbed his temples, and was about to call for someone, but he was probably too tired, and accidentally bumped into a stool, which fell to the ground with a loud noise.
Feng Tinghe was startled, his eyes hadn't opened yet, but he had already raised his head, looking at the place where the sound came from, with a daze on his face, "What's the matter? What's the matter?"
"What's wrong? It's already dawn!" He Jing was speechless. This man insisted that he would stay with him and help him, but it didn't take long before he fell asleep on the table. This elder brother is snoring, but snoring is not counted, and he still grinds his teeth.This night was really uncomfortable, that is, He Jing knew the law and did not break the law, otherwise he would really have to beat him out.
"Ah, so fast?" Feng Tinghe finally came back to his senses, opened his eyes at this time, touched his mouth quickly, and looked at the table he was lying on before, afraid that he would be ashamed to drool.He was a little embarrassed. He wanted to help, but he actually fell asleep.
He Jing ignored him, just packed up the materials and prepared to show them to Professor Lan.
Feng Tinghe approached He Jing cautiously, "He Jing, did the result come out?"
"Come out." Although he felt a little uncomfortable mentally, He Jing also knew that Feng Tinghe didn't do it on purpose, it was because of his body, so his tone softened a bit.
"Really! What's the result?" Feng Tinghe immediately became excited, he couldn't help rubbing his hands, and looked at the information in He Jing's hand.
"Look." Sensing the other party's gaze, He Jing paused for a moment, then handed the information to the other party.
Without hesitation, Feng Tinghe took it over and looked at it immediately. He was very fast, skimming some unimportant data in his opinion. The most important thing is to pay attention to the critical temperature, performance and other aspects.
As time passed, the expression on Feng Tinghe's face gradually became excited, and the hand holding the document couldn't help shaking, which showed that his heart was not calm.
"Is this data true?" He Jing asked with some disbelief.
He Jing raised his eyebrows, "Of course, or you can try again."
"Test No. [-] has the best quality, the most uniform distribution of elements, and the best performance."
"But this result is too good." Feng Tinghe still couldn't believe it. Even though he participated in the production of the finished product, he watched most of the test from the sidelines, but the data is simply against the sky. Compared with this developed alloy, it is simply a world of difference.
"I'm sure that the result is fine, and this is just the beginning. We can continue to improve the process and process later, and the data will be better by then." He Jing was very confident, patted the other party on the shoulder, He conveniently took away the information in his hand.
"If you still can't believe it, then try it again. The finished product happens to be here, so I'll go to Professor Lan first and tell him the result."
Feng Tinghe shook his head and followed He Jing, "That's no need, I'll go with you to find Professor Lan." Of course he believed in He Jing, and he also knew that there was no need to retest, after all, such a test would have to be done later. There are many times.
"Okay, let's clean up this thing first." The important thing is the experimental sample.
The two worked together, and soon He Jing and the others restored the laboratory to its original state, put the finished experiment into a box, and the two returned to the office with the things.
It was still very early, the office was facing a different direction from the laboratory, and there was no sunlight coming in. It was still dark and quiet inside.
The two stepped into the door, Professor Lan seemed to feel it, and sat up straight. His hair was still meticulous, and there was no trace of sleepiness on his face, as if he had never fallen asleep at all.
Seeing He Jing and the others, Professor Lan was very anxious, "How is it? The result is out?"
He Jing walked over and handed him the information, "It's out, the data is here."
Professor Lan took it, and he couldn't wait to roll over his numb legs and hands.As he watched, his eyes became brighter and brighter. When he saw the most important data, he couldn't help swallowing. In the end, he slammed his hand on the table, "Okay, okay... ...."
After closing the document, Professor Lan fixedly looked at He Jing, "Okay! He Jing, I did not misread you!" Everyone felt that He Jing wasted time, and he gave He Jing time.Even though he felt a little hesitant later, he still didn't force He Jing to give up, otherwise how could he have the result today!
"?" Just when Professor Lan was excited, several people walked in together. It was a few researchers from the material group. They were full of doubts on their faces at this time. Excited.
"What's the matter? Did something good happen?"
"Feng Gong, why are you here so early?"
"Yes! What happened to Professor Lan?"
A few people walked to Fengtinghe, and it happened that Fengtinghe was some distance away from Professor Lan and the others, so they couldn't help asking, their voices were very low, but Professor Lan also noticed them.
"Hahaha, you guys came just in time, and I have good news for you." He was smiling all over his eyes, but he just said this, and then he watched everyone's reactions,
Professor Lan has a gentle personality and has always been easy to get along with. Outside of working hours, everyone gets along very casually. Immediately, someone asked curiously, "What's the good news? Could it be that the higher authorities have allocated more project funds to us? "
"Yes! Professor Lan, hurry up and tell me!"
"Professor Lan, when did you start buying Guan Zi?"
"Yes, yes!"
They were indeed very curious. Judging from Professor Lan's performance, it was enough to see the good news.
Professor Lan didn't hesitate much, and pointed to He Jing beside him, "This good news is brought by our Dr. He. He has researched NbTi alloy. After testing, this alloy is an excellent low-temperature superconducting material. Alloy The distribution is even and the performance is excellent."
The news is really good news. For their entire project team, having better materials is indeed very good news.But for those of them who insist on using the Zr element and disagree with He Jing's research, this news makes them a little embarrassed.Happiness, well, it doesn't seem to be much, it's more about the shame of being slapped in the face.
Especially Jiangnan Du, who had had a not-so-harmonious communication with He Jing before, his face flushed a little, and he looked at He Jing who didn't look at him at all, and couldn't help but confirm it to Professor Lan.
"Professor Lan, is it true? Can I have a look at the experimental data?"
He just made the request, and several other people responded one after another, "Yes, Professor Lan, let us take a look?" Why did it just pass in one night, the world seems to have changed, obviously they were so happy last night It's too hard to celebrate success together with others, only to be told today that their research was useless.
Professor Lan also roughly understood their thoughts and understood them very well, so he gave them the document without saying anything.
Several people watched together, the room was very quiet, no one disturbed them, and He Jing just stood quietly, with a very flat expression on his face, not proud, let alone leaking any bad emotions.
As time passed, they read many copies of this type of information, and soon found the key data, and all the luck on their faces disappeared.Several people looked at each other, although they didn't want to admit it, but the data told them that the properties of the alloy researched by He Jing were indeed stronger than theirs, much stronger.
