The ups and downs of life in the Siheyuan

After the meal, everyone discussed some techniques and promised that he could help with dynamic balancing adjustment if they needed it.

Finally, when talking about the issue of manufacturing dynamic balancing instruments, Li Yuan raised the need for some special materials.

"Don't worry, Teacher Li, we will definitely prepare all these for you," military representative Tong Zhiyuan assured with a pat on his chest.

"Preparing piezoelectric ceramics requires a special environment, which requires maintaining a certain humidity, temperature, dust-free, and quiet environment."

They have seen similar requirements for these conditions in Western journals, and those laboratories all represent high technology.

Li Yuan just made these requests, which made everyone more confident.

"Don't worry, we will communicate with Huaqing University about laboratory matters," Tong Zhiyuan assured again.

Back at school, Li Yuan's time began to become regular again.

I went to class during the day and spent my free time in the 911 computer lab, where I participated in the modification of the mainframe.

When I go home at night, I either read books or magazines borrowed from the school library or carve national gifts.

For the national gift, he drew on the drawings provided by the Ministry of Foreign Affairs, and then made slight changes to the faucet to make it look more noble and grand.

Two days later, he was called to Vice President Dong's office.

"You guys are really good at making things. Tell me, you can really prepare piezoelectric ceramics. I know there is an institution that specializes in researching it.

It has been three or four years and there has been no results.”

"Principal Dong, I don't dare to guarantee it, but I will try my best."

"Where did you learn this?"

"There are Western preparation principles in the journals in the library, and I want to give them a try."

"Okay, I'll help you go to that research institute to get some information. Besides, you're not qualified to undertake the project independently.

You choose a professor to study with you, and of course, you have the final say on how to conduct it.

But externally, you can only be a participant."

"Okay, I have no objection."

"A good person will do his best, and you should choose the person in charge."

"Ah!" Li Yuan looked up at Vice Principal Dong in surprise.

"Can we do it, Director Li?"

Vice President Dong gave Li Yuan a meaningful look and said, "There is no problem! He will be the one to solve the problem in the laboratory."

After exchanging a few words, Li Yuan said goodbye and left.

The next day, as soon as Li Yuan left the classroom, he was blocked in the corridor by Director Li.

"Let's take you somewhere."

Director Li took Li Yuan to the farthest room on the top floor of the office building, which was about 50 square meters in area.

"How about it, can it be done here?"

"Very good, thank you, Director Li. This is the decoration plan, so I have to trouble Director Li."

He took a piece of paper with the decoration materials and decoration requirements written on it.

"Haha, it's not too demanding. Don't worry, the principal has spoken, and these are not problems.

In addition, thank you Li Yuan, I have no idea what piezoelectric ceramics are.

I know I can't help you. To put it bluntly, I'm just a cover.

Don’t worry, if you don’t call me in the future, I will definitely not come over.”

In order to win over Li Yuan, Director Li kept a low profile.

With the ability that Li Yuan has shown now, he will definitely have a bright future in the future.

As long as he stays in the Department of Mechanical and Electrical Engineering, the more achievements he will make in the future, the more honors he will receive as the head of the department.

Hearing Vice President Dong's instructions yesterday and knowing the importance of this project, he really wanted to laugh a few times.

Right from the beginning, Li Yuan brought such high-quality projects to him and the department.

Once successful, the honor goes to the Department of Mechanical and Electrical Engineering and to him as the head of the department.

Time soon entered August, and the transformation of the 8 computer was completed.

"Li Yuan, please check all the modules and wiring again," Director Jin said in front of everyone.

Since the last meeting with the school leaders, Director Jin has obviously paid more and more attention to Li Yuan.

Li Yuan also lived up to his expectations. He never missed a chance and performed well every time.

Hearing Director Jin's arrangements today, his heart was still very heavy.

This is both an opportunity for performance and a potential pitfall for making a fool of yourself.

Therefore, Li Yuan was extremely serious and even used all his mental power to scan continuously.

During the inspection, several flaws were indeed discovered. Although they are not serious at the moment, they are prone to failure after long-term operation.

Li Yuan re-welded and separated several groups of sensitive signals to avoid signal crosstalk.

There is no way, no one has the concept of EMC yet.

Even the most developed America doesn't know what EMC is.

The main reason is that the current signal speed is up to 100KHz. When the signal speed exceeds 1MHz in the future, EMC problems will arise.

Everyone watched the whole process quietly. Some people said nothing but felt very uncomfortable in their hearts.

Polite people would call him a "smiling tiger"; extreme people have classified Li Yuan as a villain who can only flatter others.

This change in mentality is normal and common, both now and in future generations.

Six months ago, Li Yuan was just a follower and assistant.

By leaving some dirty and tiring work to Li Yuan, they feel they have more time to do more important work.

At that time, Li Yuan only benefited them and did not threaten them.

Now Li Yuan has begun to occupy their position and has received the attention of the department head and school leaders.

This is hard for some people to accept.

Like a beggar, someone throws him a coin every day, with superior compassion in his heart.

A few years later, the beggar suddenly became prosperous, and he funded the business.

Someone will feel very unfair and feel that everything the beggar has right now should belong to him.

Moreover, this beggar actually pretended to be in front of him, exalting himself in front of Director Jin and putting others down.

Because the modified module is someone's responsibility.

Li Yuan checked it twice, and his serious attitude was still recognized by most people.

He turned back and nodded seriously to Director Jin.

Although Director Jin was nervous inside, he appeared very calm on the surface.

He pressed the power switch firmly.

There was no loud roar like in the past, and if there was no flashing indicator light, everyone would think that the computer had not started.

An old professor walked to the console and started operating.

The same operation results in a significant increase in output speed.

For teachers and students who deal with 911 every day, the contrast is too strong.

Half an hour later, a timing teacher took the timer and the result data output by the computer and showed it to everyone.

"Comrades, preliminary calculations indicate that this computer does indeed reach sub-second speeds."

Huge cheers suddenly came from the laboratory.

This is incredible. Now the 104 machine that the Computing Institute has concentrated the efforts of the whole country to imitate has a maximum computing speed of sub-seconds.

Moreover, the 104 computer has 22 cabinets, covering an area of ​​400 square meters. The entire machine shares 4200 electron tubes and 4000 diodes, and the operating speed reaches times per second.

After optimization, the 911 aircraft occupies less than 80 square meters, and its various indicators are far ahead of the 104 aircraft.

Everyone was making a fuss for a while, and Director Jin had to stand up and stop them.

"Please be patient, this is just the initial test, and we still need to see its long-term computing reliability."
