Back to the Republic of China to be a editor

"Preparations are underway now, and it will be held in March. When the preparations started last year, your father was also a member of the preparatory team. Mr. Li Gong, Cai Gong, and Mr. He meant to arrange your father as an executive director of the Civil Promotion Association. ... Now that your father is not in good health, Mr. Li intends to let Mr. Tang replace him as a permanent director." Sima Mianqun smiled, "Mr. Li asked me to come here this time because he wanted to have a deep talk with Mr. Tang so that he can make the right decision. Decide."

Chapter 6 In addition to atomic bombs, there are also nuclear submarines

"On August 34 and 8 in the 6th year of the Republic of China, the United States dropped two atomic bombs on Hiroshima and Nagasaki. An atomic bomb carried by a B-9 bomber had a power equivalent to 29 tons of high explosives. After the atomic bomb exploded, The huge shock wave instantly destroyed the entire city. In the past, thousands of B-29 bombers were required to carry out cover bombing to achieve this kind of destructive power....According to the Japanese archives obtained by the U.S. military, the death toll in Hiroshima reached tens of thousands that day. Although 10,000+ people were not killed on the spot, they were disabled and incapable of working due to nuclear radiation and reflective contamination. They may die after a few months, or they may die after a few years. Terminally ill and painful, and consume a lot of medical resources."

In the library of Shanghai Jiaotong University, Tang Hua sat on a chair in the most comfortable position.

In addition to the pen and letterhead, there were several publications and books on the table, all of which Tang Hua picked up from there.

Since I want to write an article, I have to put on a show. If Liu Huagang sees me writing out of thin air, I am afraid that I will be regarded as a monster in the future.

……

"The mushroom clouds in Hiroshima and Nagasaki marked the entry of human warfare into the era of nuclear weapons, and it can even be said that mankind has entered the nuclear age. The huge nuclear energy hidden inside the atom since the beginning of the universe has been mastered by mankind And release it, like an ancient monster that broke through the cage, it may bring war and disaster to mankind, and it may also become an inexhaustible resource and well-being for mankind."

……

"Currently, only the United States has the atomic bomb. This is an unprecedented phenomenon in the history of human civilization: one country has epoch-making weapons and equipment that no other country has. It is conceivable that the international situation will be extremely unbalanced. The United States alone However, the US monopoly on nuclear weapons cannot be permanent. Tang Hua believes that this monopoly on nuclear weapons will only last for a few years.”

"Some people say that the United States can do its best to keep the secret of the atomic bomb so that other countries cannot develop it. This is impossible, readers, this article does not exceed three pages, but you only need to read this article to understand to the greatest mystery shrouded in the atomic bomb."

"The atomic bombs dropped by the United States on Hiroshima and Nagasaki inspired the world and revealed the greatest secret: atomic bombs can be manufactured."

"After unraveling this secret, obtaining the atomic bomb is as simple as a child picking up a stone from the ground, and the process of unlocking the secret before is probably a child looking around to find where the stone is."

"The isotope uranium 235 of uranium and the isotope plutonium 239 of plutonium have natural neutron radiation. Therefore, when the shape and volume of these two isotopic metals exceed a certain threshold, a chain nuclear reaction will be triggered, and neutrons will bombard uranium. Nucleus, which causes the nucleus to split, releases a large amount of energy and two neutrons, and the released neutrons will hit other uranium nuclei. Two hemispheres are made of uranium and plutonium with a smaller mass, and explosives are attached. After the explosives are detonated, they will The two hemispheres are tightly fitted together; or a lot of uranium and plutonium blocks are used so that they converge toward the center of the sphere after detonation like a cut watermelon. The latter can obtain a larger explosive yield."

"The difficulty of developing an atomic bomb is not that the technical secrets cannot be penetrated, but that it consumes a lot of national and financial resources and a lot of electricity. This kind of consumption is so great that even the leader of a wealthy industrial country may hesitate before making a decision. But if a country is determined to invest sufficient national power and financial resources, it only needs to have a military industrial system and skilled pyrotechnics engineering design capabilities to break through the threshold of the atomic bomb. The atomic bomb is the first nuclear weapon, but its The technical threshold is indeed that simple. Of course, there is indeed a real ultimate secret in the field of nuclear weapons, and we will know what it is in the future."

After finishing writing, Tang Hua put down his pen and stretched his wrist, looking around the reading room.Shanghai Jiaotong University has just moved back from Chongqing, and only a quarter of the students and teachers have moved back. The campus is empty, and the library is even more empty. There are no female students, and there are not even a few students.

"Hello senior, I was looking for this book just now, and found that you took it away," a voice came from behind, "If you finish reading it, can you show it to me?"

"Oh, yes, yes, I have used up this book." Tang Hua followed the direction the student pointed and found that it was a ship's yearbook.

"Thank you." The student took the book, sat down opposite Tang Hua, and packed his schoolbag to put the book in.

"If you want to study naval ships, you should probably read this book," Tang Hua said. "It's about diesel power systems. In addition, you can also look for books on mechanics of materials online."

The student took another thick book. "There are three books on atomic physics, a book on diesel power, and a ship yearbook on the senior's desk. Which major do you major in?"

"Oh, I have already graduated, and now I am doing research on weapons and equipment, so the books I read are very complicated." Tang Hua replied casually, and then added in passing: "In fact, in the future, ship design will have a relationship with nuclear physics. , and very closely. Have you learned anything about atomic bombs and atomic reactors?"

"Understand. The United States bombed Japan with atomic bombs. Reactors are used to test the chain reaction of atoms."

"In addition to verifying the chain reaction, the reactor can also produce plutonium-239..." Tang Hua tore off a page of letterhead and began to draw a sketch on the paper, "This is the reactor, or the reactor. The core is a chain reaction. In the place, there is water wrapping the core. The water absorbs the heat generated by the chain reaction, and runs in this loop, also called the primary loop. Here, it is a heat exchanger, and the ultra-high temperature water in the primary loop transfers the heat to the Give the secondary circuit, so that the water in the secondary circuit becomes high-temperature and high-pressure water vapor, without the radioactivity of the primary circuit due to contact with the core...steam is sent here to drive a steam turbine to obtain mechanical energy, steam After it comes out, it goes into the condenser and recirculates again."

"Yes, in this way, atomic energy can be used to propel the ship!" The student understood, "In this way, a little uranium can make the ship sail for a long time. It is really amazing to use it on a warship."

"It's not just a matter of battery life." Tang Hua held up the sketched paper.

"Reactor, two circuits, steam turbine... This is a complete power & propulsion system. Compared with power systems such as diesel engines and oil-fired boiler steam turbines, what is missing?"

The student stared at the letter for a while, then stood up abruptly, almost bringing his chair down. "It doesn't need to input air! If it is used on a submarine, the submarine does not need to float up to charge!"

The corners of Tang Hua's mouth rose, and he nodded approvingly.

"Nuclear power will greatly change the design of ships. Surface ships will have unlimited endurance, and submarines will be more subversive. The mode of submarine warfare and even the entire naval battle will change in the future. But your knowledge is also very solid. , and super understanding ability.”

"Maybe it's because I'm older. When I first entered middle school, my hometown was captured by the Japanese army. After that, I went to middle school in several cities for nearly 10 years and read a lot of extracurricular books." After finishing speaking, the student asked Tang Hua He bowed slightly:

"Teacher, my name is Huang Xuhua, and I am a freshman in the Department of Shipbuilding."

Chapter 7, Commander Hal

At the gate of Shanghai Jiaotong University, the driver, Xiaoliuzi, huddled in the seat of the Ford 730. When the sun set, he finally saw Tang Hua and another student about his age trotting out of the school gate and running towards the car.

"Little Six, take the Leica in the trunk and come out, hurry up."

Little Six hurriedly opened the box, took out the camera, and loaded the film.

"Just right here, you are here facing this way, and we stand here." Tang Hua and Huang Xuhua stood under a pillar of the school gate, and then Tang Hua asked Huang Xuhua to hold the ship's yearbook to his chest, with the cover on the front.

"Okay, one, two, three, shoot!"

After putting away the camera, Tang Hua sent Huang Xuhua back to Jiaotong University.Before leaving, I also made an appointment to continue the seminar when I have time in the future, and I can bring my classmates to the meeting.

……

"Master," Sun Shi greeted him when he returned to the mansion, "Secretary Sima called in the afternoon, do you want to call him now?"

Tang Hua went to the phone and dialed.

"Mr. Tang, there is such a thing. Commander Fan Shaozeng has some money transfer and exchange business. It happens that the Yongxu Company opened by your father can help him solve it, so you see..."

"Oh? Har... Commander Fan?" Tang Hua was greatly surprised, "I've heard about it for a long time. That's no problem, that's what Yongxu Company does."

"Commander Fan means that he wants to meet you, please have a light meal. Maybe you don't know, Commander Fan is also a comrade of our Minzuo. So why don't you take Yongxu's Manager Zhao and meet Manager Zhao to handle business? Let’s talk about the preparations for promoting the people’s promotion?”

"Okay, okay," Tang Hua chuckled, "Then make it tomorrow night, Paramount."

Fan Shaozeng, a legendary figure in the Republic of China, nicknamed Fan Haer, was later promoted to Commander Haer, Commander Haer, and Commander Haer.Fan Shaozeng was born in a wealthy family. He was naughty when he was young, and his clan couldn't control him at all. Once he was even deliberately tied up and pretended to bury him alive to scare him, thus he got the nickname Fan Ha'er. In 1916, he participated in the discussion against Yuan Jun and entered the military circle.During the Anti-Japanese War, he led the army out of Sichuan to fight against Japan, and moved to Songhu, Jiangxi, Zhejiang, and Hubei successively. The record was good, and his 88th Army also became a capable army from a "mengxin".At this time, Jiang Gong came to pick the peaches, and Fan Shaozeng was emptied, and the Commander Harbin returned to Chongqing in a fit of anger.

Before Sichuan was liberated, Chiang Kai-shek gave Fan Shaozeng the title of short commander, and ordered him to form an "advancing army" to defend Sichuan.As a result, Fan Shaozeng pulled up a team of 2 people, and then there was an uprising on the battlefield.

In the few years from the victory of the Anti-Japanese War to the uprising in 1949, the biography of Fan Shaozeng that Tang Hua saw was a bit unclear. All he knew was that he seemed to have stayed in Shanghai, but he did not expect to meet him.

The next night, when Tang Hua, Sima Mianqun and others drove to Paramount, they saw Fan Shaozeng's convoy approaching ostentatiously.Four cars lined up and stopped at the gate, and seven or eight guards came out to guard the gate, and then Fan Shaozeng and his concubine (I don't know which one from No. 1 to No. 40) got out of the car and greeted Sima Mianqun and Tang Hua After a few words, we walked into the hall on the first floor together.The military dalao is not ordinary, even if it loses military power.

"Mr. Tang is really young and promising, with extraordinary ambitions! We need more young people like this to have a future." Fan Shaozeng used to hang out with Brother Pao when he was young. We all believe in the Three Principles of the People, and second, we all oppose Chiang Kai-shek, so we are comrades."

"I have admired the name of Commander Fan for a long time, and I finally see you today. Fortunately, very fortunately," Tang Hua also answered in time, "Commander Fan has made great contributions to the resistance against Japan. He killed the Japanese Lieutenant General Sakai Naoji in the Zhejiang-Jiangxi Battle. It has been eight years since the war of resistance. You can count them on one hand. It’s a pity that Japan has already surrendered, and in this era of peace, my younger generations can only admire them.”

"Hahaha," Fan Shaozeng laughed, "that devil's lieutenant general died by stepping on a land mine! In that battle, the devil's lieutenant general thought our army was retreating, so he rode a big horse and swaggered along the road and chased after him. At Sanchakou, there was a bang, which caused him to fall on his back, and one leg was broken on the spot. The devil’s military doctor carried him to the side to rescue him, but he couldn’t stop the bleeding, and then the ball died! Later, it was found out that it was buried by our 88th Army. mines, so the credit goes to the 88th Army.”

Tang Hua, Sima Mianqun, Manager Zhao, Fan Shaozeng and his adjutant were chatting at the dinner table while tasting wine and food. A man in military uniform came in among them, Fan Shaozeng's secretary.

The secretary whispered a few words next to Fan Shaozeng, and saw Fan Shaozeng ponder for a few seconds, his eyes lit up, and he said loudly: "What's there to say about it, this warehouse!"

Secretary: "Yes!"

"What is legal private property? Is it legal if he says it is legal? A department store, if the Japanese call you, if you don't withdraw, and you stay in Shanghai to do business, then you are prosecuting the Japanese, and you are a traitor! Of course the traitor's assets will be confiscated. Go and warn him." , Let the acquaintance point cooperate obediently, or I will arrest him for the crime of traitor! You go to the barracks and take a platoon of soldiers there. If he is disobedient and puts a pistol to his head, I will not believe that he is not afraid! "

The secretary said yes repeatedly, and then left the private room.Fan Shaozeng turned his neck and returned to the table.

"This is all taught by Dean Song Ziwen Song!" Fan Shaozeng said, "Song Ziwen, an old thief, has done a lot more than me!"

Tang Hua smiled and said nothing, but nodded frequently following the rhythm of Fan Shaozeng's speech.
