Back in the studio, the iron teapot on the stove was already making a harsh sound, and the lid of the teapot was rattling with steam.
Zhou Yang first took down the teapot, covered the stove lid, and immediately poured a bowl of tea for Guo Yamin and others.
"The conditions here are difficult and there is only brick tea. Let the three of you make do with it!"
Zheng Aiguo and Yang Hongguang both nodded and told Zhou Yang not to be polite.
Only Guo Yamin said impatiently: "It's too late at this point, why are you still drinking tea? Hurry up and take out your information and show it to us!"
Zhou Yang knew that the old man was anxious, so he smiled, took out the information from his bag, and handed it to his hand.
Guo Yamin didn't care about whether there was tea or not. He pulled up a wooden stool, took out his reading glasses, and leaned on Zhou Yang's simple desk to read.
Zheng Aimin and Yang Hongguang were not willing to lag behind and immediately surrounded them.
The three of them were like children reading a book. The three of them gathered around a piece of information and read page after page with extremely serious attitudes.
After just a few minutes of reading, the three of them realized that the information Zhou Yang took out was 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 actually 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, there will be a frequency difference between the frequency of the echo and the frequency of the transmitted wave, which is called the Doppler frequency.
According to the Doppler frequency, the radial relative motion speed of the target to the radar can be measured; according to the time difference between transmitting the pulse and receiving it, the distance of the target can be measured.
At the same time, the frequency filtering method is used to detect the Doppler frequency spectral lines of the target and filter out the spectral lines of interfering clutter, so that the radar can distinguish the target signal from strong clutter.
Because of this, pulse Doppler radar is more resistant to clutter interference than ordinary radar and can detect moving targets hidden in the background.
But just knowing these cannot develop pulse Doppler radar, because this 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 not very confident in the theoretical research data mentioned by Zhou Yang at first, but the more they looked at it, the more shocked they became, and they fell into it unknowingly.
After watching it for more than two hours, several people felt 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. At the moment, everyone is somewhat confused.
So, Guo Yamin took the lead to stop, and then pushed the information to Zheng Aiguo next to him.
And he pulled Zhou Yang to ask for advice on the questions that arose while reading the information 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, he has studied radar for decades and understands some basic things, so he can talk about it very well.
During the consultation and discussion, Guo Yamin and others were surprised to find that Zhou Yang looked young, but his attainments in electromagnetics far exceeded their imagination.
Not only is he not weaker than any of them, he even surpasses them.
Especially the research on pulse Doppler radar 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 this project, and even agreed to so many of his seemingly outrageous questions.
It's not that Nie Nansun is confused, but that this young man deserves it!
In this way, everyone continued discussing from three o'clock to six o'clock in the afternoon, until the sky completely darkened!
Seeing that it was almost time, Zhou Yang suddenly said: "Mr. Guo, Mr. Zheng, Professor Yang, it's almost time, how about we just do this today?"
"Would you like to stop discussing it for a while?" Guo Yamin said with some reluctance.
Zheng Aiguo echoed: "It's only what time it is, and it's not time to take a break. Let's talk for a while!"
Zhou Yang smiled and said: "Theoretical research is not in a hurry. What's more, I plan to invite a few of them to have a casual dinner in the evening. If anything happens, we can talk about it during the meal!"
"Don't be in a hurry to eat..."
Zhou Yang suddenly said: "I specially cooked the pig's head, and by the way, there is also sorghum wine!"
Hearing this, Yang Hongguang, who had been silent until now, 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 directly.
.......
The Zhou family, Li Youwei and Baoer just came back!
Throughout the whole day, mother and daughter stayed at the old house to help look after the children.
After the two sisters-in-law came back in the afternoon, the three of them started doing household chores again, and it got dark before they knew it.
Thinking that Zhou Yang might have already started cooking dinner, he came back with Bao'er.
But 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 placed on the kitchen cupboard. The basins were all filled with peeled pig head and pig trotters.
At this time, Liu Yunlong was squatting next to the stove and pulling the bellows. The fire in the stove was blowing loudly, and he didn't know what was going on in the pot.
"Comrade Liu, what's going on in the pot?"
Liu Yunlong immediately said: "Boil water to 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!"
"Yeah, there's this thing, I don't know about it yet!"
After saying that, Li Youwei immediately went back to the house and took a look. She found that although the back room was not particularly messy, it was not very tidy either, so she immediately started cleaning it up.
Just when Li Youwei had tidied up the house, voices rang outside.
Soon, I saw five or six people pushing open the door and walking in.
When Baoer saw Zhou Yang walking in the front, he immediately shouted happily: "Dad!"
Zhou Yang chuckled and immediately stepped forward to hug the little girl.
Then, he said to Guo Yamin and others: "Mr. Guo, Mr. Zheng, please sit in the room!"
Then, he pointed at Li Youwei and said, "This is my wife Li Youwei, a local!"
As soon as he finished speaking, he heard Bao'er's milky voice saying, "And me, my name is Bao'er, and I am daddy's baby!"
Everyone couldn't help laughing when they heard the little girl's words.
Li Youwei had seen a lot of Zhou Yang's leaders during this period, so she got used to it. She immediately said calmly and generously: "Let's sit on the kang. The conditions are simple. Don't be surprised!"
Guo Yamin and others did not expect Zhou Yang to get married so early, and to a local girl, so they were somewhat surprised.
But this is a family matter after all, and it is not convenient for them to ask more questions.
Then he said hello to Li Youwei, and then went into the house to get on the kang.
Zhou Yang put Bao'er down and then started preparing dinner.
Soon, the boiled pot of tea was put on the kang, and the sliced pork head was also served on a large plate.
In addition, there is a large plate of pork trotters.
Of course, there is also local Shaoguo sorghum wine!
For the staple food, Zhou Yang prepared boiled dumplings for simplicity.
But it's not ready yet. Liu Yunlong is boiling water outside and will wait until it's ready.
After the food and wine were served, Zhou Yang immediately poured wine for everyone, and the pig head feast officially began!
