"Beep beep beep!!!"

Early in the morning, Zhou Yang was woken up again by the harsh work whistle in the village.

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

Today, the institute will conduct an extension power-on test, so he has to go there early to check the preparations to avoid any accidents.

Hearing the rustling sound of dressing, Li Youwei also opened her eyes and said with a hint of exhaustion: "So early again?"

"You go to sleep first. I will heat the rice in the pot later. Just wake up and eat it!"

"Um!"

After responding, Li Youwei turned around and fell asleep again. She was really too tired.

Now that the child is still young, she needs to be fed twice every night, and she has to wake up every time to feed.

Coupled with peeing, pooping, and the occasional frightened crying, Li Youwei would have to wake up at least two or three times at night, and sometimes four or five times.

Even hard-core people can’t stand this situation!

In just over three months, Li Youwei's originally plump body due to pregnancy has 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 as much housework as possible.

After getting dressed, Zhou Yang first took the urine bucket outside and emptied it.

After washing up briefly, I got busy in the kitchen.

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

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

After coming out of home, Zhou Yang saw many members of the educated youth rushing to the brigade headquarters in groups of three or five, and occasionally he could hear their chatting and laughter.

Since the planting was relatively late this year, some of the crops that should have been hoeed by the end of July are still not finished.

Therefore, both production team cadres such as Wang Ping and Zhang Genwang and ordinary members of the educated youth are very anxious now.

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

Also, since the beginning of summer this year, it hasn’t rained very much in the past two months.

Although it's not as severe as last year's drought, it's still not good.

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

Because of this, the start of work in the village has been advanced a lot during this period.

In order to finish hoeing all the crops as quickly as possible, the feed mill and bone meal factory were also stopped, and everyone was transferred to hoeing the fields.

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

On the other hand, the feed mill had to stop operations because there was no raw material.

After last year's autumn harvest, the village relied on the production team's backup emergency grain to exchange for more than 7 million kilograms of crop straw, feeding hundreds of pigs and nearly 2,000 cattle, sheep, mules and horses.

Now that all the crop straw has been consumed, new straw will not be available for a while, so the feed mill has no choice but to stop work.

The situation at the bone meal factory is similar!

The meat processing plant has also built its own pig farm and is 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.

As a result, people in the bone meal factory don't have work to do every day.

In short, this year's crop growth is not as 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.

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

It can be seen that everyone is very excited today, but I wonder if Mr. Guo, Professor Yang and others have suffered from insomnia again.

Zhou Yang did not go to his office, but went to the testing room first. He wanted to see how the preparations were going.

When he arrived at the testing room, he saw Professor Chen Shanhe and seven or eight young people already inside.

Seeing Zhou Yang coming, everyone immediately stood up to say hello.

Zhou Yang was not polite and came to Chen Shanhe and asked: "Professor Chen, how are the preparations going?"

"The antenna, transmitter, receiver, and display have been 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 to avoid any accidents!"

"OK!"

Then Zhou Yang turned to Liu Yunlong and said: "Please inform me, the first power joint test will officially start in an hour, and the relevant branch unit must send people to participate!"

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

They must know whether their extension is functioning normally on the entire machine. If there is a problem, the extension team can learn about the phenomenon as soon as possible so that it can be easily dealt with.

"yes!"

.......

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

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

Looking at the watch, it was almost time. Zhou Yang immediately came to Nie Nansun and asked for instructions: "Mr. Nie, why don't we start?"

"Let's start!" Mr. Nie said with a serious face.

Afterwards, Zhou Yang immediately took a step forward and ordered to the comrades in the test team: "The pulse Doppler radar extension unit is powered on and the joint test has officially begun!"

After receiving the order, Zheng Aiguo, the leader of the test team, immediately said: "The target signal source search test has begun, start the radar!"

"Activate 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.

The searcher responded soon, and it was clear that the search function was fine.

The staff member responsible for the test immediately reported loudly: "Report, the radar search function is good!"

Hearing this, everyone present clenched their fists in excitement.

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 also be received. This was a good start for the test of this radar!

Under the leadership of Mr. Nie, the entire testing room burst into warm applause.

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

Although the initial test results are good, 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 all pass the test, high temperature and low temperature tests must be carried out. Only when the requirements are met can it be considered truly passed.

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

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

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

As crews restarted the radar, testing continued!

"Report: Amplitude consistency is normal, phase consistency is normal!"

"Report: The measured amplitude and phase consistency within the automatic gain dynamic range is normal."

"Report..."

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

Although it was just testing whether the radar function was normal and no detailed data was reported, such a smooth test was rare in their lives.

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

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

It can be said that so far, all the performances of the radar designed by Zhou Yang and others have far exceeded their expectations.
Chapter completed!
