My 1979

Li He and Mu Yan came back happily. When they passed by the corridor, the door of Meng Jianguo's dormitory was open. Meng Jianguo was crawling on the bed with his trousers rolled up and his butt exposed.

Li He was curious, so he went in and saw that Meng Jianguo's butt was covered in bruises and bruises.

Mu Yan looked carefully, stared at his butt, and then asked with a smile, "Why do you have so many needle holes and a bulge?"

Meng Jianguo threw away the book in his hand, leaned forward and said to the two people, "It's really unlucky. I went to the hospital to get an injection when I caught a cold. The little nurse was inexperienced and didn't dare to get the injection as soon as the blood returned. I am a scholar after all, so I didn’t lose my temper with her and told her not to be afraid and keep coming. But her mother, she took seven injections in a row, and the blood returned from each injection!"

Li He laughed like crazy, and then said, "This is what happens to bad people."

I have to give out extra injections, and I have to encourage the nurses not to be nervous if everything is fine, because in the worst case, I will get another injection.

"Your ass is so thick that it can even pierce blood vessels. This nurse is also blind." Mu Yan looked at it carefully and said, "Hey, no, you have more than seven needles. You have so many needle holes. Bleeding."

Meng Jianguo said, "So it's unlucky. An older nurse came later. I thought I should feel relieved now, but I didn't expect that it took eight injections before I went in, and I almost broke the needle."

Li He smiled and said, "Have you recovered from your cold? Do you want to get you some food?"

Meng Jianguo said, "I'm sweating all over. Is it okay to have a cold? See if there is porridge in the cafeteria and bring some for me. By the way, I can also eat some steamed buns. Bring more."

Li He said, "Okay, since you have met him, you should contribute to the training of national medical personnel."

The last class in the afternoon was his physics class. He always felt that the order of classes was wrong, but he told the Academic Affairs Office many times to no avail.

"Any physicist must be a decent mathematician. The simplest ones include quantum mechanics, advanced quantum mechanics, linear algebra in mathematics, ordinary differential equations, partial differential equations, and stochastic processes that we will cover later. Knowledge that must be mastered. When it comes to quantum field theory, it is a bit more complicated. Topology, functional analysis, and complex variable functions cannot be learned less. Therefore, for many mathematical things, we still have to study by ourselves after class. , relying on time accumulation."

After class, Guo Dong and Qi Gongxun came again.

"Teacher Li, your classes are getting more and more exciting. We listened outside the door for a while and learned a lot."

Li He was disdainful in his heart. They were both nerds and couldn't praise others. In fact, his class basically didn't teach much, mainly some physics expansion skills.

"You two are not busy lately. Come and see me when you have time?"

Guo Dong said, "Teacher Li, let's find a place to talk."

Li He said, "Go to my office."

Usually, people in the office leave after the last class, either going home or going to the laboratory.

After entering the office, he poured a cup of tea for each of the two people and said, "Drink some water."

"Good tea, it smells very good," Guo Dong said with a smile.

"Just average." This tea is indeed good tea. Li He brought it from Zhou Qing.

Qi Gongxun took out an envelope from his bag, handed it to Li He and said, "Teacher Li, we serialized your paper twice, and this is to pay you the royalties."

In order to satisfy the two people's expectations, Li He opened the envelope in person and exclaimed in surprise, "Oh, so much, it's still US dollars, this is too much."

What I was thinking in my mind was that even if you make tens of millions of dollars, you still have the nerve to give me $1,000. This effort is not directly proportional to the income.

Li He's attitude was as expected. Guo Dong smiled and said, "Teacher Li, don't be polite. You deserve this money."

"I'm not afraid of your jokes. I've always wanted to buy a washing machine, but I just need these foreign exchange coupons. Now that I have US dollars, I don't have to worry about anything. I really don't know how to thank you." Li He showed the little white rabbit The same pure smile.

Qi Gongxun put a piece of material on the table and said, "Teacher Li, take a look at this."

Li He just glanced at the cover and said with a smile, "This is my graduate thesis."

Guo Dong smiled and said, "Sorry, I just took a sneak peek without your permission."

Li He thought to himself, when did you get my permission?

He still smiled and said, "It's okay, it's okay, isn't the paper just for people to read? It's up to you two to correct me."

"Teacher Li, you said in your paper that monolithic intrinsic silicon is one of the materials for making visible and near-infrared focal planes. What is the basis for this?" Qi Gongxun asked politely.

"Do you know about the symposium on monolithic intrinsic silicon physics and chemistry held in San Diego, USA, in March this year?"

The two of them were obviously confused, but they both knew that Li He was a living reference document, and what he said must be correct, so they had to write it down in a hurry and go back to find the information.

"At least more than 30 laboratories in the United States are currently doing this research. This material has broad application prospects in satellite observation, target imaging and missile tracking."

"My paper is mainly focused on sensor technology. One of the main topics is how to improve the quality of mercury cadmium telluride materials for making infrared focal plane arrays. This array is located on top of the electronic device and consists of a large number of detection elements; the entire array The array device can produce high-resolution images. Because the spectral response range of HgCdTe is exactly in the infrared band and its operating temperature is relatively moderate, it is the best material to choose for making a better focal plane."

The two people couldn't write down the paper as fast as Li He could speak.

Li He talked eloquently for more than an hour, without giving the two of them a chance to interrupt.

"The formation of the CdTe deposition layer is a continuation of the reduction of tellurite. Its electrocrystallization nucleation mechanism changes from three-dimensional instantaneous nucleation controlled by HTeO diffusion to two-dimensional instantaneous nucleation due to changes in potential step value, deposition temperature and solution pH value. Nuclear mechanism, for HgCdTe, the kinetic steps of the electrodeposition process can be imagined as...".

After Li He finished speaking, the two of them shook their arms uncomfortably.

The two of them just wanted to ask some questions, but they didn't know how to ask, because they couldn't understand a lot of content involving polymer chemistry, physical chemistry, and analysis. How could they ask if they didn't understand?

The two of them were embarrassed.

Li He saw that the polymer formulas were written wrong in their notebooks. He took the notebooks, smiled slightly, and helped to correct them in an understanding way.

The two men lowered their heads, ashamed.

The cry in my heart can only be heard by myself. I am a top student studying in Suzhou!

When Li He saw the two of them leaving in a hurry, he smiled proudly. He didn't want to show off how powerful he was. He didn't know how many eyes Lord Ma had. Every time he came to see him, he would ask this and that, which made him a little annoyed.

I'm also a little proud, senior brother can only help you so far!

I hope this paper can help improve domestic research on intrinsic silicon in the past five or six years.
