The ups and downs of life in the Siheyuan

Seeing that there was nothing left to do, Li Yuan withdrew his telekinesis and lay down again.

When I went out the next day, I saw a few old ladies gathering together in the front yard and muttering. I knew what they were doing without even thinking about it.

The sound of Li Yuan going out to push the cart startled them. They all turned their heads and saw that it was Li Yuan, and they all greeted him.

He responded politely and rushed to school with a strong smell of gossip behind him.

As soon as he entered the laboratory, he met Director Li. He had obviously arrived early and had been waiting for Li Yuan.

Now Director Li is planning to establish a new major in the Department of Motivation, which is special materials science.

Anyway, there is no such subject now, and the Department of Chemistry was discontinued in 1952.

Materials-related work in school mainly revolves around nuclear physics.

Taking advantage of the development of piezoelectric ceramics, he wanted to expand the scale of the motor system.

He often chats with Li Yuan and is very sure that the future of sensor technology will be extremely broad.

Piezoelectric ceramics can be used in all walks of life, so he has already had this idea.

The reason why we are so active now is because we want to embrace the military and expand the influence of the piezoelectric ceramics laboratory.

The two walked and chatted, and soon entered a small conference room.

Sitting inside were four old acquaintances, Professor Zheng Jun, Professor Huang, Xiao Jian and Wang Jingxiang, as well as several senior students.

As soon as the two entered the conference room, everyone inside stood up and greeted them politely.

Especially a few students, their eyes were full of fanaticism.

They knew this junior, he was a god. No matter what they asked, he would be able to give some advice.

There is no way, this is the generation difference. The information explosion in later generations makes it easy for people to obtain all kinds of information.

Especially a certain sound contains too much knowledge about astronomy, geography, history, science, literature, etc.

Director Li sat in the main seat, and Li Yuan naturally took the first seat on the left.

The sun was shining in from the window, and from the opposite perspective, Li Yuan seemed to be glowing with a halo.

Director Li knocked on the table.

"Okay, let's have a meeting.

The next step is to carry out research on sensor miniaturization. Comrade Li Yuan is the team leader, and Professor Zheng and I are the deputy team leaders.

The team leader Li Yuan is assigning tasks below."

Several professors and teachers present at the meeting were all surprised.

Li Yuan also looked at Director Li in surprise, with a searching look on his face.

“Everyone heard it right, Li Yuan is the team leader.

As you all know, Li Yuan has completed all courses and has essentially graduated from our motivation department.

Therefore, I think he is already qualified to serve as a team leader.

I have no control over other departments, but in our department, the capable ones will be promoted and the mediocre ones will be demoted.

In the field of piezoelectric ceramics, who dares to be number one except Comrade Li Yuan?"

Director Li strongly supported Li Yuan today. Li Yuan said he was not moved, but that was a lie.

Moreover, the title was changed to Comrade Li Yuan, which seemed more formal.

Several professors and teachers also nodded slightly.

The students below wanted to applaud, because Li Yuan was their pride and their goal.

Li Yuan glanced at Director Li gratefully and said, "Teachers, classmates, Director Li, good morning.

I have a preliminary plan here, let’s see if it’s feasible.

First of all, we must establish a dust-free workshop, which can effectively avoid dust pollution. The specific indicators and requirements are. . . ".

“Secondly, we need to reduce the area of ​​ceramics. To achieve this goal, we need to modify the preparation process.

They are: raw material preparation, molding, sintering and post-processing.

Raw material preparation requires grinders and mixers. . .

Molding requires a small laminator. . .

For sintering we need a high temperature furnace. . .

Post-processing is mainly divided into polishing, coating, cutting and electric polarization. . .

In order to improve processing efficiency and yield, we need to make a fuss about the mold, that is, slotting the entire ceramic to facilitate cutting. . . "

Li Yuan repeated what he had thought about yesterday in detail and answered everyone's questions.

Everyone started discussing Li Yuan's plan. In fact, it was more about learning and in-depth understanding.

This meeting lasted a whole day, and Li Yuan also explained it for a whole day.

"Okay, please ask Professor Zheng to be responsible for the construction of the dust-free workshop. Write the plan first, and I will figure out the funds and space.

Professor Huang, please contact the Department of Precision and ask them to help us manufacture a small molding machine.

. . . ,

Others organize what they have learned today, ask questions if they don’t understand, and go to the library to study.

If anyone can't keep up with everyone, I'm sorry, I have to ask you to quit."

Good guy, Director Li has already raised his killing stick in order to succeed.

Everyone was busy, but Li Yuan was free.

With nothing to do, he began to continue to improve the preparation process of COMS, but the prerequisite was to obtain high-purity single crystal silicon.

Driven by the 56-year national scientific development plan formulated in 12, semiconductor research began in 57 and 58.

In 1958, silicon and silicon device technology was still blank in China.

What is even more serious is that under the current situation, this technology (including raw materials) was strictly blocked by various technological powers in our country.

Under such difficult conditions, Huaqing University established the Department of Semiconductors in 1958.

In 1959, he invented the technology and equipment for extracting high-purity polysilicon.

Polycrystalline silicon is the primary raw material for pulling single crystal silicon.

The entire process flow was then transferred to the Kyoto Glass Factory for production, becoming the earliest batch of semiconductor raw material polysilicon products in China.

The factory later became one of the main bases for the production of silicon materials in my country.

Subsequently, the Department of Semiconductor produced the first 1-inch single crystal silicon and began to study the preparation process of transistors.

Although there are many firsts, unfortunately, the conditions for low-cost mass production are not yet available.

What Li Yuan is thinking about is how to realize large-scale industrial production of semiconductors, increase output, and reduce costs.

In "Intermediate Materials Chemistry" there is an introduction to the process and equipment of how to prepare high-precision single crystal silicon.

But, again, none of the current technologies can suffice.

So he still has to think about how to convert, optimize and localize.

Fortunately, he already knew the answer, and the derivation process was what Li Yuan was best at.

After all, his brain is now like a grocery store, capable of interdisciplinary technology splicing.

Time passed slowly like this, and soon, the school was on holiday, and Li Yuan also returned to the compound.

This winter vacation, he has more leisure time and does not need to work overtime in the laboratory.

He also wanted to take a good rest and relax his nerves.

Every morning, I finish my morning classes, eat breakfast, walk to the Bagua area, listen to a few words of Bagua, and then go out for a walk.

Sometimes I can wander to Panjiayuan.

I was preparing to go to Panjiayuan again today, but met an acquaintance, Chen Bing, early in the morning.

"What do you mean, you're not going to work today?" Li Yuan joked.

"Let's go into the house and talk."

Seeing him mysteriously, Li Yuan had to turn around and welcome him into the house.

"Make your own tea." After saying this, Li Yuan lay down on the recliner, and the old god watched Chen Bing busy.

After Chen Bing made two cups of tea, he sat next to Li Yuan. "You will still enjoy it, but this tea is not easy to get!"

Li Yuan picked up the tea and took a sip, smiling and ignoring him.

Chen Bing chatted a few more about family matters, but when Li Yuan didn't take the initiative to ask, he had to speak himself.

"The machinery factory is encountering difficulties now. Director Lu wants me to explore your background."
