The top student must be diligent.

Chapter 239 The perfect UO structure!

"Okay, students, today's class ends here."

In the lecture hall, Xiao Yi spoke to the many students present.

Although so much time has passed, the number of students who come for his fame has become quite small, but even so, the number of students who come for his good lectures is increasing. Therefore, the number of students who come to listen to his classes is still full.

"Of course, this is also the last class of the semester."

"After that you will have to face the final exam."

"Let me remind you here that this exam will be more difficult."

Xiao Yi said with a smile that he never expected that one day he would be able to discuss the difficulty of the exam with these students.

Think about when he was an undergraduate...

Well, he didn’t really experience anything like this back then. After all, he hadn’t been in college for very long, let alone exams and such.

When they heard what he said, a bunch of students in the audience exclaimed "Ah?"

Xiao Yi didn't know whether to laugh or cry, and said, "Those of you who came here to take the class for free, please don't do it. I'm not giving you any questions."

Those students all chuckled.

There were many of them who attended every class for free and for a moment they almost forgot that they were not students of Hua Luogeng's class.

Some of them even don't have a number theory class this semester, so there is no question of taking a number theory exam.

Of course, the students in Hua Luogeng's class all looked embarrassed.

Even Xiao Yi said it was difficult, so it must be really difficult, right?
At this time, a famous student asked: "Teacher Xiao, are you going to set the questions yourself again?"

Xiao Yi chuckled: "Of course it was me who came up with it. After all, I'm the only one teaching your number theory class now, so it must be me who came up with the questions."

"Huh?~"

As a result, the top mathematics students in Hua Luogeng's class all wailed.

They have not forgotten what happened in the junior high school entrance examination.

When they took the midterm exam, they were tortured to death, especially the questions in the midterm exam seemed very simple, but when they actually started to do them, they would find that there were many difficulties or details that could stump them, and they needed to use their thinking skills to find a solution.

It can be said that the sense of accomplishment in solving this kind of question is very strong, and it feels great to do it, but considering that this is a question that you will have to do in the exam, it is quite a headache.

After all, exams are time-limited.

This can also be considered a drawback of the exam, as some students cannot finish the questions within the exam time, but given enough time, they can get full marks on a paper, whereas some students can finish the questions within the exam time limit and get high enough marks, but cannot get full marks.

Which of these two types of students is better?
For exams, the latter is of course better, but for scientific research as a whole, the former is better.

After all, in real mathematical research, time is not important. Take Zhang Yitang for example, he spent his entire life researching and finally achieved results.

Life is only a hundred years long, and success in a short period of time does not mean much, especially in the study of mathematics.

However, right now, it is still very important for these young students to get high scores in the exams. Even Zhang Yitang was a top student who was able to be admitted to Shangjing University when he was young, so the test results still reflect his strength.

Looking at these howling students, Xiao Yi smiled.

"Then, teacher, can you tell us the key points of the exam?"

One of the students was unwilling to give up and asked again.

Xiao Yi spread his hands and said, "I didn't bring a book, so you don't have to think about marking the key points."

Ever since he didn't bring his books to the first class, he realized that it didn't matter whether he brought them or not, so he never brought any books throughout the semester.

Probably he won’t bring books to class anymore.

Hearing him say this, the students in Hua Luogeng's class once again showed helpless expressions.

D!
"Okay, you students in Hua Luogeng's class, don't think about marking the key points. If you want to develop in the field of number theory in the future, there will be no need to talk about any emphasis. You need to have a deep understanding of all aspects of number theory."

"If you don't want to go deep into number theory, I also think you should have a deep enough understanding of number theory as a whole. You should know that mathematics seems to have many details, but in fact all directions are also a whole. The broader your knowledge, the more beneficial it will be for your future research. That's why our mathematics major generally pays more attention to the Qiu Chengtong Mathematics Competition, because the Qiu Competition requires a higher level of knowledge."

"Speaking of the Qiu Competition, you can sign up next semester. Regardless of whether you can win a prize or not, it's good to give it a try."

Xiao Yi said.

Registration for the Qiu Competition begins in March every year, and the finals are held around October.

So generally speaking, freshmen have to wait until their sophomore year to participate in the finals.

When he was an undergraduate, he was invited by other classmates to participate in such competitions, but in the end he refused.

Fortunately, he did not agree. Otherwise, by the second semester when his classmates would have just started their sophomore year, he would have become a doctoral student. His classmates would have been confused.

After hearing his recommendation, most of the students present also began to be eager to try out for the Qiu Sai competition next semester.

At this time, the bell for the end of get out of class finally rang.

Xiao Yi waved his hand and said, "Okay, this semester's class is over. Thank you, students. Let's end the get out of class!"

There is no need for the monitor to shout "stand up", just rely on tacit understanding.

The students present all stood up, bowed and said, "Thank you for your hard work, teacher!"

Xiao Yi waved his hand and left the classroom.

The students who stayed in the classroom began to discuss what classes Xiao Yi would teach next semester.

Students in Hua Luogeng's class also want to know whether Xiao Yi will continue to teach them other courses next year.

……

However, these are not what Xiao Yi needs to consider. Anyway, he only teaches one class every semester and it will never change.

He returned to the office, looked at what his three graduate students were doing, and then returned to his office.

Just a moment after they sat down, their dean Tang Fucheng arrived.

"Professor Xiao, is the class over?"

"Dean Tang." Xiao Yi nodded: "Just finished class, what's up?"

Tang Fucheng smiled and said, "Good news, your professor level has been upgraded to level one."

"Oh! This matter."

Xiao Yi raised his eyebrows and asked, "Wasn't I level 4 before?"

Tang Fucheng said with a smile: "You still need to ask this question? To be honest, if you hadn't applied for it yourself, you would have been a first-class professor long ago."

"Then when we were reviewing you a while ago, we found that you were actually a Level 4 professor, so we reported it directly to the higher authorities, and now you have been promoted to a Level 1 professor."

College teachers are professional and technical positions, and their job levels are also divided into 13 levels. The professor level is 1-4.

Level 4 professors are those who have just been promoted to professors, while level 1 professors are the top level. Generally speaking, only academicians can be promoted to level 1 professors. There are very few level 1 professors who are not academicians.

However, for a scholar like Xiao Yi, only a first-level professor can match his status.

"Is that so?" Xiao Yi nodded in understanding: "I really forgot about this matter. Thank you, Dean Tang."

Tang Fucheng waved his hand: "It's okay, it's good for our college."

It is naturally good for the college to have one more first-level professor. Although they are all professors outside, the difference between them is of course very clear to these units.

"Also, I also want to ask you, next semester, we plan to let you teach the real variable function class for the sophomore Hua Luogeng class next semester. Is this okay with you? Real variable function is still a little difficult for those students, and you teach it well, so we'll let you take it."

Xiao Yi waved his hand: "No problem."

"That's good." Tang Fucheng smiled, but then asked, "Then...would you consider teaching one more class? That is, teaching number theory to students in the regular class?"

Xiao Yi curled the corner of his mouth. Waiting for him here?

He waved his hand and said, "Why don't we ask them to return the first-level professor? I'd rather be a fourth-level professor."

Tang Fucheng was helpless and quickly said, "Okay, okay, I won't say anything more. You can't resign from the professor level. Young man, be more motivated."

Xiao Yi spread his hands and said, "I'm already the chief designer now, and I'm very motivated."

Tang Fucheng curled his lips and said, "Okay, just pretend I didn't say anything."

But soon he became curious again: "But, speaking of which, what is the progress of your Super Dongfang Hyper Ring? Is there really a chance that nuclear fusion can be realized?"

Xiao Yi smiled and said, "If you think it can be realized, then it can be realized. If you think it cannot be realized, then it cannot be realized. No one can predict the future of nuclear fusion."

"Tsk, then I still hope it can be realized." Tang Fucheng said: "If this thing can be realized first in our country, it will be awesome!"

As he spoke, he left Xiao Yi's office shaking his head.

Xiao Yi smiled softly.

I don’t know whether it can be realized, but if it can be realized, it will definitely be realized in China first.

【Perfect Engineering】Start.

The huge UO structure fusion device appeared in his mind.

As the thought moved, the UO device in his mind began to operate.

The perfect project allows him to see with his own eyes what changes will occur inside the device after it is put into operation.

For example, the precision magnetic levitation fluid control furnace specially used to produce MHT-7 was also developed by him using perfect engineering.

Soon, electric current was passed into the simulated HTSC-1 superconducting circuit, forming a strong magnetic field, and after deuterium-tritium fuel was injected, heating began.

With the help of various heating devices, the fuel temperature is quickly heated to hundreds of millions of degrees.

Deuterium-tritium fusion reaction began to occur, and under the magnetic field strength of 25T, all the charged plasma was well controlled and would not touch the inner wall at all.

Only the continuously produced neutrons, because they are not controlled by the magnetic field, continue to collide with the first wall material.

However, the first wall material at this time is not just MHT-7. It can be seen that some small holes are specially carved on the MHT-7 wall material.

And in these small holes, some metal liquid is adsorbed.

These metal liquids are liquid lithium.

There is another key issue in achieving nuclear fusion on Earth, and that is tritium.

There is a large amount of deuterium in seawater, but not a large amount of tritium. Of course, perhaps with the discharge of nuclear wastewater from a certain country into the sea, the tritium content in seawater may increase a little.

However, the extraction of tritium is quite troublesome and costly, and much more complicated than that of deuterium.

Therefore, it is obviously not a good idea to keep using tritium extracted from outside to maintain nuclear fusion.

However, perhaps it is the ingenious design of the Creator that allows tritium to be generated when neutrons bombard lithium, thereby achieving tritium self-sustaining in the nuclear fusion reaction.

In the past, scientists of controlled nuclear fusion have been thinking about how to make a tritium-breeding lithium blanket and cover it on the surface of the inner wall of the nuclear fusion reactor to deal with neutrons. As for liquid lithium, it is also a good choice.

However, since liquid lithium may react with the inner wall material at high temperatures, some ordinary graphite materials or carbon fibers will react with lithium at high temperatures.

However, diamond-like carbon materials can inhibit this reaction.

For example, diamond-like carbon film can inhibit the reaction with liquid lithium. However, this material may still react with liquid lithium due to structural changes under extreme conditions such as high temperature and radiation.

However, MHT-7 does not have this problem. MHT-7 itself is a material similar to diamond in structure, and its internal structure brings more stable chemical properties. Therefore, it can be said that the diamond-like carbon film has been optimized to some extent, completely avoiding the reaction with liquid lithium in extreme environments.

For this reason, Xiao Yi can add liquid lithium into this new structure without any scruples.

The liquid lithium passes through internally designed channels and eventually enters the reactor. When high-energy neutrons hit the surface of the liquid lithium, a reaction occurs immediately, generating tritium, which in turn continues to join the nuclear fusion reaction, maintaining the fusion process.

By controlling the amount of liquid lithium injected, the self-sustaining rate of tritium can eventually be maintained at 1, allowing the nuclear fusion reaction to continue uninterruptedly.

This is also an optimization of the UO structure that Xiao Yi has made over this period of time.

Of course, it is not just that. In other aspects, the UO structure has basically reached perfection.

All the problems that existed before have now been solved.

Even under perfect engineering simulation, this UO structure is already able to generate electricity!

The final conversion efficiency reached 62%!

Not only did he achieve the efficiency he planned, he even exceeded it by two percentage points!
It can be said that if he was still hesitant about whether nuclear fusion could be achieved before, now he has only one thing to say: if it cannot be achieved, he will just eat it.

"After this New Year, we will officially start construction."

By that time, the truth will gradually become clear.

At least his UO structure will definitely show that his research on nuclear fusion has reached a very in-depth level, and it will probably attract a lot of attention.

Fortunately, Trump has just taken office in the United States and is unlikely to pay too much attention to this matter for a while.

Well, it's a good time for development.

"get off work!"

After drinking a cup of tea, I will take a good rest until the new year.

In addition, he also had to prepare a smaller UO structure in preparation for that time.

After all, not everyone would agree that he would build a new fusion device that is larger than the tokamak planned for ITER.
