Chapter 157: A Simple Test

Kim Jong-hee and Lien Hak-wen guessed correctly, and there is indeed room for improvement in these new materials.

However, there is one thing they guessed completely wrong, the reason why Liu Feng released these papers was not because the research was in a bottleneck, but because he was willing to publish it if he liked it, how could these people think so much.

Even if he no longer needs to prove himself by sending papers, there are always people who think that he is exhausted, and it is good to slap these people in the face if he sends some papers every once in a while.

Although many people who get the journal will think that none of Liu Feng's papers can reach the realm of large-scale promotion and use, so they regard these papers as pioneers, but for Liu Feng, this is not just a pioneer, because the process optimization of porous carbon fiber microcrystalline graphite oxide composites is in full swing, maybe it will be successful in ten days and a half months。

It's like fighting a landlord, how can there be a king who blew up from the beginning!

As for whether it will inspire people and improve the progress of other people's research, Liu Feng doesn't care at all.

If someone can really innovate on his basis and make something at that time, he will not feel any discomfort at all, but will feel very honored.

After all, on the road of water treatment reverse osmosis membrane materials, he has sunrise in the east and I am the only invincible, and once the porous carbon fiber microcrystalline graphite oxide composite material comes out, I am afraid that it will be lonely and defeated, at that time, it is really not even a worthy opponent anymore, he will be very lonely on this road alone, it is really unbearable!

This is one of the reasons why he published those new material papers, of course, this guy is not without the evil idea of using these things to trick others.

In short, the good and the bad are half and half, and Liu Feng's mind is also very entangled.

Time really flies. .

A week passed like this, and after Academician Wang went to a meeting somewhere, as soon as he returned to the institute, he asked Liu Feng to go to the office.

As soon as Liu Feng entered the door, Boss Wang looked over and said with a smile.

"Boy Feng, first of all, I have to congratulate you for publishing so many high-level papers in the journals Nature, Science, and The Lancet!"

"Boss, I didn't expect you to know. ”

Liu Feng touched his head with a smile, and said a little embarrassed.

"It's just that you probably think I'm young and vigorous and can't hold my breath!"

After all, he has seen a lot of this kind of argument on the Internet recently:

Under the guise of caring about him, many 'experts and professors' accused him of being young and vigorous, unable to hold his breath, and publishing these things completely to make wedding dresses for others. After all, it's just a matter of releasing a few of the good phased results, why don't you release them all and keep them for yourself to continue researching?

Silly, huh!

Professor Wang smiled schemingly: "This is something that Academician Duan Xue should be anxious about." You still have a long time with me, and there are still many opportunities to be trained, so what do I have to worry about? Besides, Scholar Duan is not in a hurry, I think I should have a lot of confidence in you kid, why should I be this bad guy!"

Yes, you're really a good person!

"Actually, I have already told Boss Duan in advance, I already have a draft of the rest of the things, and I have basically completed most of them, and I have handed over some irrelevant things to Professor Wu Qingquan to do, so you don't have to worry about ...... at all."

"Hehe, what am I worried about? Really, even if you really can't study the things in the back, I'm afraid it's a good thing for me, just to stop your kid from doing chemistry again!"

Academician Wang joked.

Liu Feng: ......

I really didn't expect you to be such a 'narrow-minded' boss!

Seeing that Liu Feng stopped talking, Academician Wang smiled and decisively ended the topic.

"Let's not talk about it, let's talk about us! What do you think of the information I gave you?"

"Almost. ”

Liu Feng thought for a while.

Wang Yifang originally just asked casually, but she didn't expect this guy to think that he had seen it all, and suddenly said in surprise: "It's almost? It's only been a few days? According to my estimate, your kid will have to spend more than half a month!"

Liu Feng also smiled: "Maybe it's because our memory is better! Otherwise, boss, you can test me now, we also want to turn around in advance or something, but I hope your old subordinates will be merciful." ”

Academician Wang looked at Liu Feng carefully for a while, perhaps thinking that this guy didn't look like he was lying, so he opened the drawer, took out a few pieces of A4 paper from it, and put them on the table.

"That's okay, I'll just test you two questions!"

As he spoke, he handed Liu Feng a pen.

I was prepared!

Liu Feng took the pen and paper and looked at it.

The first chapter of the A4 paper is about the rules of the laboratory and the like, which he has already read and memorized, so it is very simple.

"Boom"

Liu Feng picked up his pen and wrote, and after a few minutes, it was easily done.

And the next 2 A4 papers, Liu Feng only glanced at them, and his brows twitched fiercely.

The two questions that are said to be good, but there are four questions clearly written on the A4 paper, and the last two questions are not easy to look at.

"What, I don't understand?"

Academician Wang asked with a smile.

"How so!"

Liu Feng smiled and turned his gaze to the topic, with a thoughtful expression on his face.

"It just doesn't seem easy. ”

Academician Wang smiled and didn't speak, Erlang's legs were high, just waiting to see him write.

Not so easy?

You kid know it's not easy?!

After reading the information given by Lao Tzu in a few days, if you don't give you a dismount, you kid won't be able to go to heaven?

How to say that he is also an academician, and these topics were originally used to test the professional knowledge level of those interviewers when he recruited graduate students.

If you can answer two questions correctly, then you are basically qualified, if you can make three, then it can be said to be excellent, if you can do four, then you are a genius!

Speaking of which, several doctoral students he has brought with him are all able to make three questions, but he has not yet met one who can complete four questions, even if these students are not the same questions, the difficulty of the questions is about the same.

Just when Academician Wang was waiting for Liu Feng to start writing, Liu Feng had already gone through all four questions, although he couldn't say that he had a plan, but he also had some ideas.

The first question, fill in the blanks, examines the concept of neutron flow, which is completely a scoring question in Liu Feng's view.

Neutron flow is one of the objects of high-energy physics research, assuming that the high-speed neutron flow is controlled by a cylindrical particle flow, its cross-sectional area is S, the energy of each neutron is e, and the velocity of the neutron flow is u____________.

According to the title, the volume of the neutron flow passing through the unit time is V=Su, and the energy per unit volume is Q=SuA, so the number of neutrons passing through the neutron flow section per unit time n=Qe=SuAe, and the energy passing through the unit area per unit time along the direction of motion is Q′=QS=uA, so the answer is: SuAe;Au.

Liu Feng guessed that Boss Wang must have taken many exams before, and the reason why he came up with this kind of question was probably to give those people a comfort. Because, the first question is so easy that high school students can answer it!

So, the second question: the wave function of a three-dimensional isotropic harmonic oscillator can be written as Ynlm, and l=N-2n, then what is the degree of degeneracy at a definite energy (N+3/2)hY?

The second question may be a little difficult for undergraduates, but for a genius like Liu Feng who is above the master's level, it is as simple as drinking water, and Liu Feng wrote down the answer: (N+1)(N+2)/2.

Seeing Liu Feng's speed of doing the questions, Academician Wang nodded with satisfaction.

The first two questions are very simple for him, and some powerful undergraduates may be able to answer all of them correctly!

If he couldn't even do these two questions, then he would definitely wonder how these people he took the exam were admitted to graduate school!

And Liu Feng can do it so quickly, which basically meets his requirements.

Nodding his head, he continued reading.

Question 3.

This difficulty is not comparable to the previous two questions, this question can be said to be on the basis of the second question, directly increased by an exponential power!

Whether this kid can answer it or not, it's really not certain!

Staring at Liu Feng's answer sheet carefully, Wang Yifang waited eagerly.
