The ups and downs of life in the Siheyuan

Li Yuan has always kept a low profile in school and his life is relatively monotonous.

Every day is in the classroom, laboratory, home, and occasionally goes to the library to read the latest journals.

So whether in class or at school, he only heard his name but never saw him.

It's a pity that the action this time was too big and shocking. Of course, there was also Director Li’s deliberate push.

Li Yuan once again became popular in school.

In one and a half years, I studied all professional courses by myself and got excellent results in all of them.

Such a man of God is what every student wants to be like.

Following the heated discussion, his identity as an artist was revealed again, and suddenly, there was another burst of wailing on the campus.

Everyone sighs, if there is brightness, why should there be beauty?

Of course, there are also many fans and fans, and many people are inspired to become the next Li Yuan.

This resulted in many students burning the midnight oil and working late at night, which invisibly improved the learning atmosphere of the entire school.

The school is also happy to see the results.

Some leaders wanted to publicize Li Yuan's deeds in the school, and it became an issue at the meeting.

After discussion, he was finally suppressed by the principal.

After counting Li Yuan's achievements in this year and a half, everyone was shocked.

Participating in the development of parallel four-cylinder diesel engines seems to have played a significant role.

Participated in the research and development of 911 computers. Due to a proposal, the design indicator was directly increased to times per second.

The independent research and development of brushless DC motors has become a confidential project of the military and cannot be used in civilian products for the time being.

Independently researched piezoelectric ceramics and designed a dynamic balancing instrument, which has also become a national confidential project.

There is also a northwest mission, but of course these cannot be discussed yet.

According to the report of the teacher who came back, this kid is also a martial arts master.

Even the notorious prairie wolves were killed by him alone.

Not to mention the value of force, as far as the scientific research results are concerned, any professor can be honored for a lifetime, but he is only a sophomore student.

Such a coquettish student can be properly promoted, but full exposure will probably have the opposite effect.

Now the Piezoelectric Ceramics Laboratory has become the main laboratory of the Department of Motivation, with staff expanded to 3 professors and more than 20 resident students.

The Department of Radio Engineering and the Department of Precision Instruments both wanted to be included in this laboratory, and they also lobbied leaders at all levels.

Director Li defended to the death and refused.

He said he was anxious and asked the school to return Li Yuan. They now lack a leader in the gas turbine laboratory.

The leaders had no choice but to maintain the status quo.

Li Yuan took advantage of the situation and gave Li Yuan the title of technical expert.

This allowed other departments in the school to find no fault. Instead of occupying the school's job title, he created a technical virtual position of his own.

In this way, there is no qualification for employment.

The school also acquiesces to this, so as a student, Li Yuan now has another identity: a technical expert in the piezoelectric ceramics laboratory.

In order to protect Li Yuan, the school treats him as a mere participant to the outside world. Even for piezoelectric ceramics, he is only a deputy team leader.

On this day, Li Yuan had just walked out of the piezoelectric ceramics experiment and was about to go home when he met Director Li.

"Xiao Li, come and sit in my office." Director Li smiled like a flower.

Li Yuan smiled and nodded.

Director Li's office.

"Come and try some of the new tea that my old man got. I like it a little bit."

Li Yuan followed Mr. Xu's example, first smelling the fragrance, then tasting the alcohol. He closed his eyes and pretended to be 13, and exhaled, "Good tea!"

After one operation, Director Li looked even happier.

"There are about two taels here, and I don't know much about tea. I'll lend you flowers as a gift to Buddha."

Li Yuan was not pretentious and accepted it happily.

Otherwise, Director Li might have other ideas.

After chatting for a while, Director Li turned to the main topic, "You are rarely here at this stage. I will inform you about some laboratory conditions."

"Hey, Director Li, I don't dare to say that. No matter when, I will be your student."

Director Li was so happy that he smiled from ear to ear after hearing what Li Yuan said.

"Actually, everyone knows that you are the academic leader of this laboratory. At this stage, the laboratory has also made some small achievements based on your work.

It’s up to you to decide how to develop next.”

Director Li has always kept his attitude very low. Li Yuan clearly knows why, but he still feels very satisfied in his heart.

"In the application of piezoelectric ceramics, the theoretical research and prototype production of pressure sensors have been completed, and the indicators are on par with currently used testing tools.

Especially in low voltage applications, our piezoelectric ceramics have more advantages.

The only problem now is that the yield rate of piezoelectric ceramics is too low and the shape of the sensor is too large, which limits the application scenarios.

The military wants us to more than double the size. Let's see if there is a good way."

"The main reason for the low yield rate is the need for a dust-free workshop. In addition, I have to think of a solution from the preparation process.

As for reducing the volume, this is easy, just reduce the area of ​​the ceramics as much as possible."

These are all explained in the skill book, but the investment is slightly larger at the beginning, which is not conducive to development.

Now that all parties have seen its value, it is understandable to invest appropriately.

“We also thought of this method, but the ceramic area becomes smaller, it is easier to be damaged during cutting, and the yield is lower.

Moreover, the difficulty of later polishing and electrodeposition also increases accordingly.”

Director Li took out two Hongta Mountains, handed one to Li Yuan, and gave one to himself. Li Yuan picked up a match and lit it for both parties.

"There is still a way. I will lead the team to tackle the problem tomorrow," Li Yuan exhaled smoke and said firmly.

What was waiting for was Li Yuan's promise, and Director Li felt relieved.

He was very worried that Li Yuan went to the Department of Radio Engineering regardless of the work here.

Although it can be said that it can still come up with some tricks, the lack of Li Yuan's laboratory means that it lacks a kind of temperament.

When Li Yuan was here, both teachers and students in the laboratory were very confident.

Li Yuan had only been away for less than a month, and the laboratory seemed to have dropped to a different level.

He also reflected on the fact that it is not that these teachers do not work hard or are not smart.

On the contrary, these people are extremely smart.

But they lack some of Lee Won's unique confidence, vision and flash of inspiration.

These cannot be obtained through hard work.

That's why Director Li was determined to tie Li Yuan to the laboratory.

No, as soon as the question was raised today, Li Yuan thought of a solution.

Although he did not elaborate, from his confident expression, Director Li believed that it would be possible.

Back home, Li Yuan began to think about how to optimize the process.

Many techniques in the skill book cannot be directly copied. The biggest problem is that the corresponding technology and equipment are not yet available in China.

He has to design a manufacturing process that is in line with the current technology implementation capabilities based on the actual situation.

A breakthrough in one technology can lead to the advancement of other technologies.

This process of technology stacking BUFF has long been proven by the history of Western technology development.

His reimagined piezoelectric ceramics are divided into four main steps: raw material preparation, molding, sintering and post-processing.

Of course, the prerequisite is to establish a dust-free workshop.

These all required him to conceive and design step by step. With a rough idea, Li Yuan could sleep peacefully.
