Time flies faster and faster, and in the blink of an eye, it has reached June 23rd.

I've been waiting for a long time to finally wait for today, and I've dreamed for a long time and finally made my dream come true...... Andy's singing resounded on campus, heralding another season of defense.

And Liu Feng has been waiting for this day for a long time.

According to the regulations, the instructor should have avoided the defense, but because Liu Feng's situation is special, and because Duan Xue is an academician, the defense teachers were all invited by him, so naturally no one cares about this kind of trivial matter.

In addition to Duan Xue, the other two, one turned out to be President Tan, and the other was Academician Liu Yiqing from the Chinese Academy of Sciences.

Needless to say, President Tan is also an academician, but what makes Liu Feng puzzled is that he is an old man who has come to make a fuss, after all, he is engaged in biology, and Liu Feng is now going to defend chemistry.

Another academician Liu Yiqing, Liu Feng doesn't understand, anyway, the little friend invited by Duan Xue must be not small.

Standing on the podium, Liu Feng looked as usual.

This moment has been waiting for him for a long time, although there is not much time to prepare, but he is not stage frightened after a long time on the battlefield.

On the podium, there is a PPT.

After a brief self-introduction, Liu Feng began to describe his paper and report the main content and results of the paper.

In fact, it didn't take long to get to this process, and it was only six or seven minutes before and after, after all, the next questioning session was the most important part of the defense!

"On page 11, line 12 of the paper, it is mentioned that your thin film material mainly refers to the catalytic reaction of water and gas, and the ethylene generated by the propylene disproportionation reaction will pass through the film, so why did you not choose to synthesize the catalyst and the thin film together in the way of coupling for the propylene disproportionation reaction?

Unlike ordinary defense judges, Academician Liu Yiqing doesn't matter who you are, his questions go straight to the heart of the paper.

If he was just an ordinary undergraduate, he might have been stumped by this kind of question, but who was Liu Feng, who was he an ordinary undergraduate? He didn't even look at the paper, because he knew exactly what was written on page 11.

"Because the coupling method is more complex for the loading mode, it is not advisable in the first place in terms of cost, and secondly, a series of chemical reactions that occur in the coupling mode will have unpredictable chemical changes to the inorganic film......

Picking up the chalk, Liu Feng wrote on the blackboard while speaking.

Liu Yiqing looked at the blackboard, his eyes gradually narrowed as Liu Feng's handwriting gradually narrowed, and he nodded from time to time; the question he had just now completely exceeded the amount of knowledge he had at the undergraduate level, even if it was required by the standard of a doctoral student, this Liu Feng classmate also performed flawlessly, so he was very satisfied.

After Liu Yiqing asked, Principal Tan next to him also spoke: "I noticed that the experimental data in your paper is relatively small, according to the general subject research, there should be a lot of trial and error experiments, so why is there almost no trial and error data in your paper?"

This question made Liu Feng stunned for a moment.

Sure enough, there will always be people who pay attention to this aspect.

What's the reason, it's not because we opened it!

Liu Feng coughed lightly and said, "This problem can be explained by two reasons. On the one hand, it is because the selection of the route is more appropriate in the early experimental route demonstration, and on the other hand, because the later experiments are relatively successful, there are few trial-and-error experiments, and the reference of the data is not valuable, so this situation occurs. ”

"Xiao Liu, I'm going to criticize you here. Professor Tan shook his head and said in a serious tone, "What is the purpose of our experiments, except for the final results, we may not consider other things? This is not the mentality that a scholar should have, you know, you look at how many great discoveries of scientists are inadvertent, or even simply experimental mistakes." Therefore, Xiao Liu, we should still strive for perfection in learning in the future, even if the possibility of the other one is so small that there is almost nothing, but we still can't let it go. ”

Duan Xue on the other side also nodded: "Boy, you have to remember Professor Tan's golden and jade good words, in this regard, you should really pay more attention to this aspect, and don't jump to conclusions easily." ”

Professor Liu Yiqing suddenly smiled: "Old Duan, don't deliberately embarrass Liu Feng, sometimes it is luck to engage in scientific research, and other young men get results without much trial and error, this is people's luck, think about what you are doing when you are 18 or 9 years old, and you are still holding on to the content of the book and reading to death, right?"

"Eh, Lao Liu, I don't like to hear this sentence, what depends on luck, in this era, have you seen a few academics who rely on luck? If you don't have a down-to-earth research foundation, you will hurt Zhongyong one day. Duan Xue shook her head, "Boy, remember, don't be so impetuous in the future......"

The three of them are all academicians, and Liu Feng stood on the stage, and could only humbly accept the opinions and criticisms of a few people like a puppet, and he couldn't insert a word at all.

Finally, when the three of them finished arguing, they saw Duan Xue look up at the clock hanging on the wall: "There is still a little time, do you have anything else to ask?"

"You guys!" Academician Liu Yiqing shook his head, where Duan Xue and Tan Tianwei were nitpicking about Liu Feng before, it was a completely different kind of love.

"What else do you ask, even if we let a few of us do it, it may not be possible to do a good job with Liu Feng! ”

So, Liu Yiqing directly filled in the score on the form, then stood up with a smile, looked at Liu Feng, and nodded with satisfaction.

I heard that Lao Duan accepted a very talented apprentice, and this contact is worthy of its name: "Young man, you are very talented in chemical experiments, and at your age, the basic professional knowledge is also relatively solid, I hope you will make persistent efforts in the future, work hard to specialize, don't live up to the expectations of the teachers, and don't waste your own precious talent, come on!"

"Thank you, teacher. Liu Feng bowed sincerely, and the stone in his heart finally fell, at this moment, is he about to graduate?

"No thanks, the defense is over, you go out first, and the result will be notified to you later. Professor Liu Yiqing waved his hand. Then Liu Feng walked out of the classroom.

Looking at Duan Xue, Professor Liu smiled and said jokingly: "Old Duan, where did you find this young man? I have never accepted such a young child in these years, and I see that the person is also old and is about to retire, or, you see that we will discuss and let me try young people too?"

Duan Xue directly rolled her eyes and looked at this old friend: "Don't even think about it! Your Chinese Academy of Sciences has snatched a lot of good seedlings from all over the country, and there is even a juvenile class, and you still say that there are no young people? Seeing that we have finally produced a talent, you want to make trouble, dream!"

Tan Tianwei on the side also helped: "Yes, Lao Liu, you are so unkind, wherever there is a disturbance, you have to run over and pick up a hair!"

Liu Yiqing shook his head and sighed: "You guys, you're still so stingy!"

In fact, he didn't really want to snatch Liu Feng or something, after all, they Huake Academy of Sciences didn't know how much better than Huada, who he hadn't seen? This time, on the one hand, it was to meet the request of an old friend, and on the other hand, it was also to satisfy his curiosity.

Duan Xue always bragged to him, saying that he had accepted a new apprentice, this apprentice was highly talented, and he couldn't say that he would be able to produce a Nobel Prize or something in a few decades, as soon as he heard this, he really didn't believe it, Nobel Prize, who to bluff? But when he saw it today, he also had to sigh, this classmate Liu Feng really had the strength to win the award!

After sighing, Professor Liu couldn't help but bless his old friend in his heart: to receive such an excellent heir to inherit the mantle, there is no regret in this life!
