Chapter 320 11 Major Events in Mathematics (33)

After finishing dinner in the cafeteria, Chen Zhou took Yang Yiyi for a walk by the nameless lake.

When I returned to the library, a lot of places in the self-study area had been taken up.

But their old positions were vacant.

I don't know when, Chen Zhou and Yang Yiyi's position in the library has been tacitly accepted.

Perhaps this phenomenon will not change until the two leave Yanda.

It's just that when the two of them graduated from Yanda and left, the old positions they were familiar with were the positions that everyone tacitly reserved when they were together.

All of a sudden, it became the object of contention.

Even before the opening of Yanda's library, there was a long queue.

Especially when the exam season was approaching, the queue was even longer.

Many people wanted to grab the seat that Chen Zhou had sat in, and get a taste of this boss' aura of dominance.

Turn on the computer, open the wrong question collection, take out the draft paper, and replace the pen refill.

Chen Zhou devoted himself to selfless work again.

The intense pulse energy effect is the basis for the surface treatment and modification of metal materials by intense pulsed ion beams.

Accompanied by the energy deposition and dissipation process with ions as the carrier, it is the thermodynamic process of the ion beam interacting with the metal target.

However, purely through data calculation, it is necessary to ignore the part of radiation loss, and simply consider that all ion energy is converted into heat energy, and becomes a heat source acting on the target surface.

This corresponds to the pulse energy deposition distribution with energy spectrum and time structure.

After Chen Zhou completed the basic calculations, he needed to perform calculations on the computer through the TRIM program.

After sorting out his ideas, Chen Zhou began to write on the draft paper: "The study of mechanical processes can be divided into three categories according to the energy flux deposited on the target surface and the corresponding irradiated surface state."

"Low-intensity energy flow (≤1J/cm) keeps the surface solid; medium-intensity (1-5J/cm) can melt the surface; high-intensity (>5J/cm) can evaporate and ablate the surface."

"Refer to the experimental data of this material surface modification to study the thermodynamic process..."

After Chen Zhou finished writing the entire draft paper, he put the draft paper on the computer keyboard and started calculations on the new draft paper.

"One-dimensional temperature field coupled fluid dynamics equations that need to consider dissipation effects such as heat conduction..."

After calculating part of the data, Chen Zhou thought that the calculation of this thing seems to have to use C++ language to compile the corresponding calculation program.

Frowning slightly, he habitually took a pen and tapped on the draft paper.

"Do you want Senior Lafang to join the gang?"

After thinking about it, Chen Zhou finally decided to come by himself. It shouldn't be difficult to learn, and it should be regarded as laying the foundation for informatics in applied science.

More importantly, this subject is the subject of Dean Yang, and the current data is mainly derived from existing experiments, and it is not possible to ask outsiders for help.

Unlike the previous project at the 43rd Institute, most of the data are known documents, which are publicly available documents.

Quietly turning his head to look at Yang Yiyi who was immersed in his own world, Chen Zhou slowly removed the scratch paper covering the computer keyboard, quietly opened the literature search engine, began to search for C++ language content, and searched for courses in the Department of Computer Science with Baisou teaching materials.

Looking at the searched content, Chen Zhou sorted it out briefly, and began to download documents.

As for the course materials, he only memorized the names of the materials.

Afterwards, you can ask Fang Jieming to borrow textbooks, or go to Shuimu University for a stroll.

After all, the Yao class of Shuimu University is known as the existence of "half of the country's elites gather in Shuimu, and Mizuki's half-heroes are in Yao class".

Now Chen Zhou, only mathematics and physics have been systematically taught by himself. As for other subjects, he has the idea of ​​learning them after using them.

Of course, this method has obvious disadvantages.

But for Chen Zhou who was short on time, it was the best solution.

After reading the literature for a while, Chen Zhou rubbed his eyes, thinking that if he had time in the future, he would systematically study the knowledge of chemistry, biology, and informatics.

Time soon came to the closing time of the library.

Chen Zhou and Yang Yiyi stretched at the same time, and they smiled at each other.

This feeling of fulfillment, as well as the results on the table, all prove the harvest of time.

After sending Yang Yiyi back to the dormitory, Chen Zhou sent Fang Jieming a message about borrowing textbooks.

Fang Jieming replied quickly.

Not only said there was no problem, but also made a list of books for Chen Zhou.

Some of them he has seen, some of which he is looking at.

There are others that he is going to watch.

The point is, Fang Jieming specifically stated that this is the book list of the Yao class at Shuimu University.

Looking at the reply message, Chen Zhou said repeatedly in his heart, this senior is really good, and they deserved to win the UPC gold medal together, which is very interesting!
With the book list, the rest is easy.

Back in the dormitory, Chen Zhou quickly turned on the computer, ready to check the purchase of books in the book list online.

After all, he is now a millionaire anyway, rich!
What Chen Zhou didn't notice was that when he turned on the computer, the three of Zhao Qiqi were watching him.

All three of them had admiration in their eyes.

When Chen Zhou was about to ask which websites are better for buying books, he noticed the radiant eyes of the three of them.

Chen Zhou was taken aback, and said loudly: "Fuck, why are you looking at me like this?"

Zhao Qiqi got up immediately, walked behind Chen Zhou, squeezed his shoulders and beat his back again.

Zhu Mingli quickly took out the big bag of snacks, put them in front of Chen Zhou, and poured another glass of water by the way.

Li Li turned his head and typed quickly on the computer.

Chen Zhou was even more confused, what kind of trouble is this?
The last time I did this, it seemed like I was asking for an introduction, but now how can I have a female classmate to introduce?

The ones in Yiyi's dormitory, the ones in the dormitory next door, and the ones in the dormitory next door, have you introduced them all?

When Chen Zhou was puzzled, Li Li stopped typing on the keyboard, pulled down the mouse, unplugged the power cord, and walked towards Chen Zhou holding the computer.

"Boss, please look!"

Zhao Qiqi and Zhu Mingli also gave way at the right time, and said at the same time: "Big brother is awesome!"

At this moment, Chen Zhou suddenly thought of something, and quickly glanced at the content on the computer.

"No wonder so many students look at me when I go to the cafeteria to eat!" Chen Zhou thought to himself.

The computer is about the 2015 major events in the mathematics world in 11 selected by the American Mathematical Society, which is AMS.

In the United States, it has already been widely publicized by some mainstream media.

And here, there is Chen Zhou's name.

The selection of AMS is based on the timeline, so Chen Zhou's name and his deeds are ranked last.

However, at the end of 2015, he was able to get rid of the people and things in the previous half a year and successfully entered the list.

It is enough to show Chen Zhou's strength!
