Chapter 177

Xu Heng asked a question?

Dean Nie and the three professors answering the question?

This, this, this! ! !

What is this routine?

He Xuezhang was dumbfounded, he thought he heard it wrong.

But Fang Zhonggui emphasized it again, "Yes! Don't worry about questioning the question you asked, first look at the answer we gave."

Xu Heng smiled awkwardly, "Let me think about it! You just watched me pose the question, and I haven't had time to prepare the answer myself! Give me a few minutes, and I'll sort it out!"

It only takes a few minutes!

Between the lines of Xu Heng's words, it is so domineering!

Dean Nie and Professor Fang Zhonggui trembled in their hearts.

The four of them worked together to solve this problem within ten minutes!

Xu Heng only needs a few minutes?

???

These four people have been shocked too much today!

"I'm a little numb! But...!"

"But it still feels weird, doesn't it?"

"Ok!"

"If he hadn't seen it with his own eyes, who would have believed that Xu Heng could come up with a test question that we would have to revise for four or five days before we could come up with it in just a few minutes!"

Xu Heng looked at the problem-solving ideas and answers of Dean Nie and the four, and nodded slightly.

But soon, he was also writing and drawing on straw paper.

It really only took a few minutes.

He raised his head slowly, "After looking at you and me, I calculated with myself. The answer is the same. The only difference is that my thinking is a little different from yours."

Think differently!

!!!

Xu Heng actually had a different idea on this question?

The four of them froze for a moment.

They looked at each other!

This is the simplest way they can think of to reach a consensus.

"this……! "

"You... this, this, the four of us worked together for almost 20 minutes to complete the topic, but you, unexpectedly, only took a few minutes!"

"My God!"

At this time, the four people who were serious, completely ignored that the door of the office hadn't been closed yet.

In front of the door, there is also He Xuezhang.

And He Xuezhang himself didn't dare to stay any longer after hearing this.

He quietly closed the door and left silently.

He was completely shocked!

From head to toe, it felt like an electric shock, and the whole person began to doubt life.

"He is really posing questions to the dean and professors, not only posing questions, but also having a different way of solving problems from the professors!"

"What's worse, he spent less time than those four!"

"!!!"

"No wonder he didn't say what he was up to in the group! It turned out that he said it, and no one would believe it!"

"Damn! This low-key classmate Xu Heng!"

At this time, He Xuezhang's cell phone was ringing non-stop.

Because he said in the group before that he was going to find Dean Nie, to give Dean Nie the key, and see what Xu Heng and Dean Nie were doing!

But now, if he sent it, he would know what they were doing!

But he can't say it!

Click on the group, there are a lot of news.

But most of them are @own.

Wang Hanshan, "@He Xuezhang, senior, how's it going?"

The group leader, "@He Xuezhang, yes! Senior He, how is it going? What are they doing?"

Many people are asking.

At this moment, He Xuezhang was caught in a dilemma.

If it is said in the group!

What is the face of Peking University School of Physics?

This matter is so important, he can't say it, absolutely can't say it.

He can only choose to lie.

Just about to send a message...

"Senior He, you are here! I can't wait, I came to see you! How is it? Is Xu Heng in the office?"

"He is with Dean Nie?"

"Did you give the key to Dean Nie? So, have you seen Xu Heng? What are they doing inside!"

It was Wang Hanshan.

He Xuezhang immediately deleted the edited lie.

"Ahem! See you, they are chatting inside, and Professor Fang."

"Chat... Hey! Xu Heng is too bold! While chatting with Dean Nie and Professor Fang, he even chatted with us!"

"Is it too boring?"

He Xuezhang had black lines on his face.

"Don't ask, let's go! Don't make trouble!"

"Xu Heng also said in the group that he will contact us when he finishes his work."

"Let's go!"

He Xuezhang dragged Wang Hanshan away.

And in the office.

Xu Hengzheng and Dean Nie shared their thinking on solving the problem.

"Assuming that the number of moles of gas in container A is n1 after the valve is closed again, and the number of moles of gas in container B is n2, then the total number of moles of gas is n=n1+n2."

"Consider the gas in the two containers as a whole, assume that the temperature of the gas in container A is T1' after the valve is closed again, and the temperature of the gas in B is T2. After the valve is closed again and before the valve is opened, the internal energy of the gas..."

"..."

"Because there is no heat exchange between the gas entering vessel B and the gas remaining in vessel A, the portion of the gas remaining in vessel A from the opening of the valve to its reclosing undergoes an adiabatic process..."

"..."

"So get..."

Xu Heng wrote down the ratio of the total mass.

Molecule: 2-α[(R/c+R) power]-α[C/(c+R) power]

Denominator: 2-α-α[(c+R) power]

This result is the same as that of Dean Nie and the others.

But the way of thinking is quite different.

Dean Nie and Fang Zhonggui, the three professors, dared to look directly at Xu Heng after a very struggling inner struggle.

"Student Xu Heng, can I ask you a question?"

Fang Zhonggui spoke with sincerity.

Xu Heng, "Professor, tell me."

Fang Zhonggui took a deep breath, "Hiss... What I want to ask is, can you... solve all the questions we gave you in 10 minutes?"

Xu Heng immediately shook his head, "No, no, no! It's not what you think! Guys, I just encountered a topic that I'm good at, so I'm so fast! I'm not good at it..."

amount……

If you just want to say that you are not good at it, you will be slower.

But after thinking about it, ten minutes is not too slow!

Before I knew it, I was in Versailles.

Xu Heng was slightly embarrassed.

Dean Nie and Fang Zhonggui no longer knew how to express their inner feelings.

"I think, even if I see UFOs and aliens next, I will calm down!"

"Student Xu Heng, you, this, you... you you you... are you still human? You can't be an alien!"

Xu Heng, "Professors, believe in science!"

Pfft!

believe in science?

But you can solve a problem in a few minutes, how can we believe it!

Fang Zhonggui picked up the question, "This is mine! Everyone! You can't compete with me!"

The other two professors panicked, "Student Xu Heng! Give us one each!"

"It will save us another week of racking our brains!"

Dean Nie patted his forehead!

Got it!

You professors have found a knack for opportunism!

Did you still think that Xu Heng was not up to the task?

Also said that this is a postgraduate topic?

Why are you all vying to be babies now?

Seeing Dean Nie's helpless expression, Fang Zhonggui said sincerely, "Dean Nie, I admit that I underestimated Xu Heng's ability!"

"You are very clear about the level of knowledge you need to know to write questions for graduate students."

"Sometimes, you know a lot and know a lot, but when it comes to asking questions, the nature is completely different!"
