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

"Beep beep beep!!!"

Early in the morning, Zhou Yang was awakened again by the piercing whistle of the village going to work.

Reluctantly pulling his arms out of his wife's arms, he began to put on his clothes lightly.

Today the research institute is going to conduct an extension power-on test. He has to go there early to check the preparations to avoid accidents.

Hearing the rustling sound of getting dressed, Li Youwei also opened her eyes, and said a little tiredly, "It's so early again?"

"Go to bed first, I'll heat the rice into the pot later, just wake up and eat!"

"Ok!"

After answering, Li Youwei turned around and fell asleep again, she was really tired.

The child is still young now, and she has to breastfeed twice a night, and she has to wake up every time she feeds.

In addition to peeing, pooping, and occasional frightened crying, in short, Li Youwei would wake up at least two or three times a night, and sometimes four or five times.

In this case, even the hardest hitter can't stand it!

In just over three months, Li Youwei's plump body, which was originally plump due to pregnancy, lost weight at a speed visible to the naked eye.

This made Zhou Yang very distressed, so he went home every morning and evening, and tried to help Li Youwei with housework as much as possible.

After getting dressed, Zhou Yang first lifted the urine bucket outside and poured it out.

After a simple wash, he started to get busy in the kitchen.

After breakfast was ready, he, Liu Yunlong and Xiao Wenhui ate first, and put Li Youwei and Bao'er's share in the pot to warm.

After eating, Zhou Yang and Liu Yunlong left home and rushed to the research institute.

After leaving home, Zhou Yang saw many educated youths rushing to the brigade headquarters in small groups, and occasionally heard their chatting and laughing.

Due to the late planting this year, some of the crops that should have been hoeed by the end of July have not been hoeed yet.

Therefore, whether it is Wang Ping, Zhang Genwang, the production team cadres, or the ordinary educated youths, they are very anxious right now.

After all, whether this year's harvest is good or not depends on these crops.

What's more, there haven't been many rains in the past two months since the beginning of summer this year.

Although it is not as severe as last year's drought, it is also not very good.

Therefore, the crops that have been hoeed in advance also need to be irrigated, which requires a lot of manpower.

Because of this, the time to start work in the village was much earlier during this period.

Even in order to hoe all these crops as soon as possible, the feed mill and bone meal factory were also shut down, and everyone was transferred to hoe the fields.

On the one hand, of course, it is because of insufficient manpower!

On the other hand, the feed mill had to shut down because there were no raw materials.

After the autumn harvest last year, the village relied on the production team's spare emergency food to exchange more than 700 million catties of crop straw, feeding hundreds of pigs and nearly [-] cattle, sheep, mules and horses.

Now those crop stalks are all consumed, and new stalks will not come down for a while, so the feed factory can only stop working.

The situation at the bone meal factory is similar!

The meat joint factory has also built its own pig farm, and it is also producing feed itself, and consumes a lot of bone meal.

So since the beginning of this year, the bone meal sold to Babaoliang Village has been reduced by about half.

In this way, the bone meal factory does not have work every day.

In short, this year's crop growth is not very good as Zhou Yang expected at the beginning of the year.

Almost everyone knows that production reduction is almost a certainty, but they don't know how much to reduce.

When the two came to the research institute, they saw that Mr. Nie, Mr. Guo, Zheng Aiguo and others had already got up, and then rushed to the cafeteria one after another.

It can be seen that everyone is very excited today, but they don't know if Mr. Guo and Professor Yang are suffering from insomnia again.

Zhou Yang didn't go to his office, but went to the testing room first, he had to see how the preparations were going.

When he came to the testing room, he saw that Professor Chen Shanhe had brought seven or eight young people inside.

Seeing Zhou Yang approaching, everyone immediately got up to say hello.

Zhou Yang was also polite, and came to Chen Shanhe and asked, "Professor Chen, how are you preparing?"

"Antennas, transmitters, receivers, and displays are installed and ready for testing!"

Then Chen Shanhe said again: "But just to be on the safe side, I will take my comrades to check the circuit again, so as to avoid accidents!"

"Row!"

Then Zhou Yang turned to Liu Yunlong and said, "Go ahead, the first joint test will officially start in one hour, and the relevant extension team must send people to participate!"

Although the test is only divided into several groups and does not require everyone to participate, the relevant German researchers must be present.

They must know whether their extension is normal on the whole machine. If there is a problem, the extension group can know the phenomenon at the first time, which is easy to deal with.

"Yes!"

.......

At eight o'clock in the morning, the sky was already bright.

The testing room of the research institute was already full of staff members. As Nie Nansun, Niu Weitong, Guo Yamin, Zheng Aiguo, Yang Hongguang, Chen Shanhe and others arrived one after another, the atmosphere at the scene gradually became tense.

Looking at the watch, it was almost time. Zhou Yang immediately came to Nie Nansun and asked for instructions: "Old Nie, shall we start?"

"Let's get started!" Old Nie said with a serious face.

Afterwards, Zhou Yang immediately took a step forward, and ordered to the comrades in the test group: "The joint test of pulse Doppler radar extension is officially started!"

After receiving the order, Zheng Aiguo, the person in charge of the test team, immediately said: "The search test for the target signal source begins, start the radar!"

"Activate the radar!"

As the radar staff turned on the power and started the radar, the antenna arranged at the front of the iron frame began to rotate.

Soon the search engine responded, and obviously the search function was fine.

The staff in charge of the test immediately reported loudly: "Report, the radar search function is good!"

Hearing this, everyone present clenched their fists excitedly.

Zheng Aiguo forced himself to calm down and said loudly: "Receive the signal source!"

"Report, the target signal source is receiving smoothly!"

Everyone was even more excited. The search function of the radar was fine, and the signal from the target signal source could be received. This was a good start for the test of this radar!

Under the leadership of Mr. Nie, the whole test room burst into warm applause.

The applause subsided slightly, and Zheng Aiguo came over to ask for instructions: "Mr. Nie and Comrade Zhou Yang, there is no problem with the radar search and signal transmission and reception. Do you want to conduct a three-channel test?"

Although the initial test works well, this is only a basic function, and passing the test itself is expected.

So everyone knows that the test has just begun and the real difficulties are yet to come.

Especially the receiver amplitude, phase consistency, etc., which are prone to problems.

Even if these have passed the test, high temperature and low temperature tests must be carried out. Only when all the requirements are met can it be considered as a real pass.

Nie Nansun looked at Zhou Yang, and said, "You decide, whether to try the basic functions a few more times, or go directly to the third channel!"

"Go to the third channel!" Zhou Yang said decisively.

After receiving the instructions, Zheng Aiguo immediately ordered the staff of the test team: "The three-channel test starts, first test the receiver amplitude..."

Testing continues as the crew restarts the radar!

"Report: Normal Amplitude Coherence, Normal Phase Coherence!"

"Report: Amplitude-phase consistency measured within the dynamic range of automatic gain is normal."

"Report..."

As the staff of the test team reported the test results one by one to everyone at the scene, everyone including Nie Nansun was shocked by the test results.

Although they are only testing whether the radar function is normal and have not reported detailed data, such a smooth test is rare in their lives.

The normal operation of the function does not mean that it is advanced, but it can show that the design idea is mature and there are few defects!

If the parameters can still meet the requirements, it is perfect!

It can be said that up to now, all the performances of the radar designed by Zhou Yang and others have far exceeded their expectations.

If they can really pass the whole machine test, Nie Nansun feels that it is necessary to seriously consider Jiang Lao's proposal a few days ago!
