Rebirth 1975: Tore up the call-back order at the beginning

Back in the studio, the iron teapot on the stove had already made a screeching sound, and the lid of the teapot was rattled by the steam.

Zhou Yang first took down the teapot, and after covering the stove lid, he immediately poured a bowl of tea for each of Guo Yamin and the others.

"The conditions here are tough, only brick tea, the three of you can make do with it!"

Both Zheng Aiguo and Yang Hongguang nodded, telling Zhou Yang not to be polite.

Only Guo Yamin said impatiently: "It's so critical, why don't you drink tea, quickly take out your materials and show us!"

Knowing that the old man was in a hurry, Zhou Yang smiled and took out the information from the satchel, and handed it to him.

Guo Yamin didn't care about whether there was any tea or not, so he directly pulled a wooden stool, took out his reading glasses, and leaned over Zhou Yang's simple desk to read.

And Zheng Aimin and Yang Hongguang were not far behind, and immediately surrounded them.

A few people are like children reading a comic book. The three of them gathered around a document and looked at it page by page with an extremely serious attitude.

After reading it for a few minutes, the three of them realized that the materials Zhou Yang presented were very unusual.

Not only is the expression simple, but it is also very clear and easy to understand.

In fact, they all know the working principle of pulse Doppler radar, and it is not much different from other radars.

That is, when the radar emits a pulse wave of a fixed frequency to scan the air, if it encounters a moving target, the frequency difference between the echo frequency and the frequency of the transmitted wave appears, which is called the Doppler frequency.

According to the size of the Doppler frequency, the radial relative motion speed of the target to the radar can be measured; according to the time difference between the transmitted pulse and the received time, the distance of the target can be measured.

At the same time, the frequency filtering method is used to detect the Doppler frequency spectral line of the target, and the spectral line of the interference clutter is filtered out, so that the radar can distinguish the target signal from the strong clutter.

Because of this, pulse Doppler radar has stronger ability to resist clutter interference than ordinary radar, and can detect moving targets hidden in the background.

But just knowing this, it is not possible to develop pulse Doppler radar, because it not only involves Doppler frequency shift, but also uses a large number of integrated circuits.

Because of this, pulse Doppler radar has become the most important cutting-edge technology in various countries today.

Guo Yamin and others were actually not very confident about the theoretical research materials mentioned by Zhou Yang at the beginning, but the more they looked at them, the more shocked they became, and they fell into it unconsciously.

After watching for about two hours, several people felt that their eyes were a little tired.

In addition, the theory itself is still very profound, and it is impossible to understand it all so quickly. Right now, everyone is somewhat puzzled.

Therefore, Guo Yamin stopped first, and then pushed the information to Zheng Aiguo who was next to him.

And he pulled Zhou Yang to ask for advice on the problems that arose when he read the materials just now!

Of course, Zhou Yang will not be stingy about this, no matter what questions Guo Yamin asks, he will answer them one by one.

Soon, Zheng Aiguo and Yang Hongguang also joined in.

Although Zhou Yang is not particularly proficient in integrated circuits, after all, he has studied radar for decades and knows some basic things, so he can say that he is pretty close.

During the consultation and discussion, Guo Yamin and others were surprised to find that Zhou Yang looked young, but his attainments in electromagnetism far exceeded their imagination.

Not only is it not weaker than any of them, it even surpasses them.

Especially in the research of pulse Doppler radar, it shocked them all.

At this time, they all understood that Nie Nansun would value this young man so much that he insisted on letting him host the project, and even agreed to so many seemingly outrageous questions from him.

It's not that Nie Nansun is confused, but this young man deserves it!

In this way, everyone discussed from three o'clock in the afternoon to six o'clock, until the sky completely darkened!

Seeing that the time is almost up, Zhou Yang suddenly said: "Old Guo, Mr. Zheng, Professor Yang, it's almost time now, why don't we just do this today?"

"Would you like to stop discussing for a while?" Guo Yamin said with some reluctance.

Zheng Aiguo echoed, "What time is it? It's not time to rest. Let's talk later!"

Zhou Yang smiled and said: "Theoretical research is not in a hurry, not to mention that I plan to invite a few of you to have a light meal in the evening. If there is anything else, we can talk about it during dinner!"

"Don't rush to eat..."

Zhou Yang said suddenly: "I specially boiled pig's head, yes, and sorghum wine!"

Hearing this, Yang Hongguang, who had been silent all this time, suddenly said, "How about we eat first?"

Guo Yamin thought for a while and said, "Okay, let's eat first!"

Zheng Aiguo: %￥#￥%...

Three to one, the result is clear at a glance.

Later, at Zhou Yang's invitation, the three old experts followed Zhou Yang back home.

.......

The Zhou family, Li Youwei and Bao'er just came back!

For a whole day, their mother and daughter were helping to look after the children in the old house.

After the two sisters-in-laws came back in the afternoon, the three sisters-in-laws started the daily routine again, and it was getting dark before they knew it.

Thinking that Zhou Yang might have already started dinner, he brought Bao'er back.

It's just that when I came back, I found that Zhou Yang and Fan Debiao were not there, and only Liu Yunlong was busy in the kitchen.

What shocked her even more was that there were three large enamel basins on the cupboard in the kitchen, and the basins were full of peeled pig's head and trotters.

At this time, Liu Yunlong was squatting by the stove and pulling the bellows, the fire in the stove was whistling, and he didn't know what was going on in the pot.

"Comrade Liu, what are you doing in the pot?"

Liu Yunlong immediately said: "Boil water and make tea. Comrade Zhou Yang told me to start making tea after five o'clock. He will invite people home for dinner in the evening!"

"Ah, there's another thing, I don't know yet!"

After speaking, Li Youwei immediately went back to the room to have a look, and found that although the inner room was not particularly messy, it was not very tidy either, so Dang even hurriedly tidied it up.

Just as Li Youwei cleaned up the house, voices sounded outside.

Soon, five or six people were seen pushing the door and coming in.

When Bao'er saw Zhou Yang walking in the front, he immediately shouted happily: "Dad!"

Zhou Yang chuckled, and immediately stepped forward to hug the little girl.

Afterwards, he said to Guo Yamin and the others: "Mr. Guo, Mr. Zheng, please sit in the room!"

Then, he pointed to Li Youwei and said, "This is my wife Li Youwei, a local!"

As soon as the words fell, Bao'er said in a childish voice: "There is also me, my name is Bao'er, and I am Dad's baby!"

Everyone couldn't help laughing when they heard the little girl's words.

Li Youwei has seen a lot of leaders with Zhou Yang and other leaders during this period, so she got used to it, and immediately said generously: "Everyone sits on the kang, the conditions are simple, don't be surprised!"

Guo Yamin and others didn't expect Zhou Yang to get married so early, and he married a local girl, so they were somewhat surprised.

But after all, this is their family business, and it is inconvenient for them to ask more questions.

Immediately, he greeted Li Youwei, and then went into the house and went to the kang.

But Zhou Yang put Bao'er down, and then made dinner.

Soon, the boiled pot of tea was served on the kang, and the sliced ​​pork head was served on a large plate.

In addition, there is a large plate of pork trotters.

Of course, there is also local Shaoguoliang liquor!

For the sake of simplicity, Zhou Yang prepares boiled dumplings for the staple food.

But it's not ready yet, Liu Yunlong is boiling water outside, and it will be done after a while.

After the food and wine were served, Zhou Yang immediately filled the wine for everyone, and the pig's head feast officially began!

ps: Try to update at a unified time in the future, but please click the reminder button after reading the book, that thing is still very important to the author, and the amount will be given the next day, which is an important basis.

After the endless coma, Shi Yu suddenly got up from the bed.

He took a big gulp of fresh air, his chest trembling.

Confused, puzzled, all kinds of emotions came to my mind.

where is this?

Afterwards, Shi Yu subconsciously observed his surroundings, and then became even more at a loss.

A single dormitory?

Even if he was successfully rescued, he should be in the ward now.

And my own body... How come there is no injury at all.

With doubts, Shi Yu quickly swept his gaze across the room, and finally settled on a mirror by the bedside.

The mirror reflected his current appearance, he was about seventeen or eighteen years old, and he was very handsome.

But the problem is, it's not him!

My previous self was a handsome young man in his 20s who had been working for a while.

But now, no matter how you look at it, this appearance is only the age of a high school student...

This change left Shi Yu in a daze for a long time.

Don't tell him that the operation was a success...

The body and appearance have changed. This is not a question of whether to have surgery or not, but a fairy art.

He turned into a completely different person!

Could it be... that he crossed over by himself?

In addition to the mirror on the bedside which was obviously placed in a bad feng shui position, Shi Yu also found three books beside it.

Shi Yu picked it up and took a look, the title made him silent for an instant.

"Necessary Beast Breeding Handbook for Novice Breeders"

"Postpartum Care of Pet Animals"

"Guidelines for Evaluation of Alien Beast Ear Girls"

Shi Yu:? ? ?

The titles of the first two books are quite normal, what's the matter with you in the last one?

"cough."

Shi Yu's eyes were serious, and he stretched out his hand, but soon his arm stiffened.

Just when he was about to open the third book to see what it was, his brain suddenly felt a sharp pain, and a large amount of memories flooded in like a flood.

Icefield City.

Pet breeding base.

Trainee pet keeper.To provide you with the rebirth of the great god Cangyue 1975: tearing up the order of returning to the city at the beginning
