Xia Yangjie didn't know what he was smashing, and it took a four-year cold bench, which actually impulsive.

I just listened to a few teachers who have just reached the next time, and Xia Yangjie chased his notebook.

Xia Yangjie is divided into Pu Chi University, graduated from the domestic famous university four years ago.

He is not just learning high molecular chemicals, but learning mathematics.

He went to the chemical system, it was ridiculous, it was because the female teacher who was originally teaching mathematics in the chemical industry, two months could not go to class, the leaders of the chemical system require a math teacher to come. Top her lack, so, Xia Yangjie who just graduated was allocated.

Xia Yangjie is not a nerd, but it is really lacking talent in the lectures.

In his view, jump from a formula to another formula is a simple matter, do not need to list the detailed derivation process at all.

But when he used this way to lectone, his student hangs a large piece of large.

The leader is looking for a few times, and personally go to the classroom to listen to his lectures, and finally determine that this person is not a material that teaches mathematics.

Fortunately, the female teacher who came to have a child had returned to the maternity leave. Xia Yangjie took a deep regret and intake, glorious off.

Of course, the chemical system cannot be borne. After research, Xia Yangjie is adjusted from the public class teaching ceremony to the polymer teaching and research room, which has undertaken the work of fiber winding model research.

The fiber entangle is a composite production technology in the 1940s. Briefly, the fiber soaked in the resin is wound into a core mold according to a certain lap, after drying, after drying, take off the core mode, A fiber resin product can be obtained.

The principle of the fiber resin is a bit like the reinforced concrete we can see, the resin is equivalent to cement, which is equivalent to a steel bar, which can enhance the strength of material strength.

The most common fiber resin is FRP.

This is a plastic product reinforced with glass fibers.

The fibers used in the fiber wrapped products are except for glass fibers, as well as aramid fibers, carbon fibers, and the like.

Fiber wound technologies can be used to make pipes, pressure vessels, solid rocket engine housings, etc., is a new technology for materials.

My country has begun research on fiber wrap technology at the end of the 1950s. At that time, it was mainly serving the cutting-edge defense technology needs of two bombing a star.

Seventy-eighti years.

my country has introduced several fiber winding equipment from West Germany, Italy, Japan, and the United States, and has carried out localized work.

The method of the fiber wound is a bit like the process of wrap the cotton gauze into the yarn ingot, and the wound core mold is rotated at a certain speed, and the fibers move along the axial direction, thereby forming a circle of winding lines.

Xia Yangjie's task in the polymer teaching room is to help do this research in this regard to calculate the speed of the core model running speed and the filament of the fiber spun, to ensure that the wrapped structure meets the design requirements.

Teachers in the Polymer Technologies are all learning chemistry, and the idea of ​​mathematics is not good, so there is some obstacles to such models.

But I said that Summer Jie, who has mathematical talent.

This model is simply like a few different geometric questions, and he solves these problems in three and five in addition.

No one thought, it is these exercises, let Xia Yangjie have in this area, and it cannot be cleaned.

The density, angle, fiber overlap of the fibers, and the like.

There is a significant impact on the performance of fiber wrapped products, which affects the mechanism, and it is said to be a chemical problem. It is better to say a very charming mathematical problem.

Furthermore, conventional fiber wrap products are mainly convex symmetric rotary bodies, for asymmetric products, or so-called double concave rotating bodies.

How to achieve winding processes, is also a topic that requires a lot of space operations.

All of these topics make Xia Yangjie feel fun.

After completing the tasks handed over the teaching and research, Xia Yangjie began to conduct his own research.

He introduced a large number of mathematical concepts into polymer studies, proposed a multi-freedom fiber winding and spreading model, as well as gradient projection methods based on an elegant matrix, based on SVD decomposition, the weighted least squares method, inverse sports Learn the loop solution method, etc.

It's too easy to play.

In any field, the leader is a genius, and people who lead the lead in the lead is a madman.

Xia Yangjie's research on the theory of fiber wraps, and he took the lead than his peers, and its result is that there is a tall and widow, no one to ask.

Throughout the polymer teaching and research room.

No one knows what Xia Yangjie is doing, the differential geometry of him written out, in addition to him, no one can understand, and I don't know what this thing is.

Xia Yangjie couldn't find a colleague who was discussing with himself in the teaching and research room. I wrote the article to contribute. Editing the Editorial Department did not know that he wrote to the end.

For four years, he did not even publish a papers.

So in the eyes of leaders and colleagues, he became an unpredictable, and he would only take some mathematical formulas.

This time, Qin Hai and Lu Xiaolin went to the chemical system to open the seminar, and the academic secretary also notified Xia Yangjie to participate, but Xia Yangjie has already been cold in this meeting, he does not think that the bureaucrat from the government department can I can understand his theory.

Besides, he is not very recruited, why bother to make this lively? So, when he was a meeting, he stayed in the teaching and research section, and the formulas that only understand only himself.

The teachers of the teaching and research have fallen by the Qin Hai, and one is ash, and there is no words.

After returning to the teaching and research room, everyone stated that the setbacks of today were indignant, and some people touched the conscience to say that Qin Hai's knowledge is indeed. Some research directions he raised, and there is a few points to himself.

During this time, there was a teacher who had been able to take a daily relationship with Xia Yangjie and knocked on the table of the Taxi, and said to him: "Xiaoxia, you have not been able to go today.

If you go, you will give the localization to the town.

"What do you mean?"

Xia Yangjie pushed myopia glasses on the nose and asked.

"Today's domestic office has come to a young young young, giving us everyone.

I ponder, what you usually do, we all don't understand, if you say that you are young, you can say it, at least, we will not cover the whole army.

The teacher said half joke.

In fact, in his heart thinks about another thing, he is hoping that Xia Yangjie can also participate in this meeting, and is also in the Qinhai, so his psychology is balanced.

The ancients said, and good things must be exclusive. When you are unlucky, you have to pull someone else, this teacher has always been very favored by such ancient training.

Xia Yangjie didn't think so much. He just asked strangely: "What kind of young, can put our entire teaching and research room, he said?"

The teacher picked important content, introduced a few words to Xia Yangjie, said: "Yes, Xiaoxia, are you do not get wrap around? I see the topic of them, there is also a free-shape fiber winding process , Don't you try? "

"Free shape fiber winding process?"

Xia Yangjie eyes bright, "Are they really say?"

The teacher threw the information issued by the venue to Xia Yangjie, said: "You look at it yourself, I don't understand this field, I don't know what they said.

Xia Yangjie opened the information. When he saw the question mentioned by the teacher, he wrote the instructions of the problem at a veteran, and he only felt that he was hot, and he stood up.

"Mr. Hu, where are they?"

Xia Yangjie asked.

Mr. Hu is finger, saying: "Mr. Qian sent them out, this will still be far away.

How, Xiaoxia, do you really want to find them? "

"me……"

Xia Yangjie has two sounds, I don't know how to say it.

He smiled sorry to Mr. Hu, and then touched a notebook from the drawer, hugging in his arms and rushed out of the teaching and research room.

"Old Hu, how come Xiaoxia?"

Some people noticed that Xia Yangjie's is the same, and he went back to Mr. Hu Xi.

Mr. Hu laughed: "I just said that I have two sentences in Xiaoxia, Xiaoxia is probably the young young people who chase the two localization office.

"Haha, I see Xiaoxia and they are tall and don't climb.

A teacher commented on sour.

"If you can't say this, people are called tall and widow, you don't appreciate the level, you can't hear the Yadi.

Another teacher said with the same weird tone.

"Oh, it is indeed a tall and widow.

However, I am still a good thing in my Lower, and the sun is white, we can't get it.

The teacher said long.

These old generation of intellectuals are very good, although it is a part of the chemistry, it is not stranger.

Xia Yangjie didn't know how others talked about him, even if he knew, he would not care, because in the past few years, this kind of comments heard in his mutant have been a lot.

He ran out of office, came to outdoors, looked up to the direction of the school gate, seeing two young people who have different young people with different school teachers and students, walking away, and quickly chasing the past.

At this time, Qin Haibei and Lu Xiaolin heard the footsteps behind him, stopped back and looked back, Xia Yangjie asked: "Do you have two in the Purnsan Domestic Office?"

"Yes, we are domestically produced, what is it ..."

Qin Hai did not move as asked.

"My name is Xia Yangjie. It is the chemical system of high molecular teaching and research, I study the theory of fiber wrap, but it is very embarrassed, there is no building tree.

I would like to ask, do you really want to do free shape fiber winding process? "

Xia Yangjie replied four places.

PS: This chapter calculates eight o'clock in the morning, I didn't expect to write so difficult ... The fiber wrap is a very complicated and complicated issue. Look at the thesis will look silly.

I hope that the concept in the article is not written. As for the precision, then it is free.

Finally ... ask for a monthly ticket.
