Chapter 199

Xu Heng fled and even gave up the sign-in reward, which was enough to see his decision.

It doesn't matter if Zhu Tiesen catches up or not!

Even if he catches up, Xu Heng will not go back.

This Professor Zhu, make trouble!

I, Xu Heng, am not such a casual person!

If you ask me to do some things, do you need to ask for my consent first?

Even if I am willing, it is impossible for you to force me to do it in public so suddenly!

Xu Heng didn't like to see Zhu Tiesen like this.

Zhu Tiesen chased after him.

"Student Xu Heng! Student Xu Heng! Wait a minute!"

Zhu Tiesen also realized the problem.

He originally thought that Xu Heng was embarrassed and needed a step, so that if he gave a lecture on stage, everyone would get used to it, and Xu Heng would not be burdened.

But he was wrong!

Xu Heng refused from the bottom of his heart!

He doesn't want this!

Therefore, Zhu Tiesen, who has come to his senses, must catch up with Xu Heng and explain this matter clearly, so as not to leave any pimples because of it.

In case it made Xu Heng unhappy, he wouldn't even participate in the Mathematical Olympiad?

This is not worth the loss!

Xu Heng heard Zhu Tiesen calling himself, but he didn't stop.

He goes his own way.

Turn ahead!

Go downstairs!

Turn again!

Anyway, it was staggered with Zhu Tiesen.

Taking out his mobile phone, Xu Heng was just about to call Han Honghu.

A girl with a sweet smile appeared in front of her, "Teacher! Hello!"

Xu Heng was stunned for a moment.

And behind this girl, there are two other girls, both of whom look good.

Xu Heng, "Uh...you, how are you? Are you...?"

"I'm your fan! Teacher Xu!"

Xu Heng, "???"

He looked at Xu Heng with a blank face.

The two girls behind pulled her aside.

"What's the matter with you? Didn't you say that you know each other?"

"Why did he look blank just now, as if he didn't know you at all?"

The girl was anxious, "You have to believe me, we really know each other, and he told me that question!"

"In the library!"

"If you don't believe me, ask him!"

The girl returned to Xu Heng, "Mr. Xu, it's me! That day in the library..."

Only then did Xu Heng remember.

It was her!

"Hi, I'm Ling Yurou, these two are my roommates!"

"Nice to meet you, Teacher Xu Heng!"

Xu Heng, "Uh..."

It feels weird!

Being called a teacher by the senior sister of Tsinghua University...

Cough!

And you're dressed a little cooler!

JK skirt...

It will be misunderstood!

"By the way, aren't you cold in your clothes like this?"

"Forehead……"

Ling Yurou was embarrassed, "I didn't expect to be complained about..."

In fact, she dressed like this mainly because of Xu Heng!

Xu Heng is her idol!

When you meet an idol, do you need to dress up carefully?

Moreover, Xu Heng is a high school student, and she mustered up the courage to dress up like this mainly to cater to Xu Heng.

Unexpectedly, Xu Heng complained about it.

"%#￥￥..."

The other two girls smiled and exposed, "Ms. Xu, Yurou is your fan, and she cherishes your classical Chinese essay like a treasure! I don't know how many times I recited it in the dormitory."

Xu Heng, "If I remember correctly...you should be studying physics, right?"

Ling Yurou and the three nodded.

"Yes! But it doesn't affect my love of writing!"

"Of course, without delaying your studies."

"That... Mr. Xu, are you free now? Can I ask you to go to the library?"

Xu Heng, "?"

Ling Yurou, "At Senior Zhou's suggestion, I checked you out. It doesn't matter, it just overturned my three views! I asked Senior Zhou again, and it is said that you still have a fan base."

"After I joined the group, I got to know it again!"

"So you are so powerful...!"

Xu Heng interrupted Ling Yurou, "Wait! So... what?"

Stop blowing it all the time!

Get to the point!

Ling Yurou, "I would like to ask you to give us a little tutoring in physics, can you? It's just a morning, and I invite you to have dinner and milk tea at noon!"

Xu Heng raised his eyebrows, okay!

If he knew how to courtyard, Zhu Tiesen would also look for him.

Might as well disappear for a few hours.

"Let's do it~!"

Ling Yurou, "Long live!"

"Let me tell you, Teacher Xu is very powerful! You will see it later!"

Xu Heng, "Can you stop calling me Teacher Xu... I'm not very old, senior sister."

Ling Yurou, "You can teach us, you are the teacher! Hello teacher!"

Xu Heng, "%￥#￥%￥#..."

Enter the library study room.

Three girls, and the appearance is not bad.

Surrounded by Xu Heng.

This made many students in the self-study room look at each other with admiration.

"???"

There was more or less envy in their eyes.

Die of thirst, die of thirst, die of waterlogging, die of waterlogging!

And these three women are really here to learn.

They belong to Tsinghua University!

Senior sister of Tsinghua University!

Of course, learning is the most important thing.

Ling Yurou, "Teacher Xu...this question..."

topic:

A spring vibrator performs simple harmonic vibration, and its vibration curve is shown in the figure.What is its period?What is the initial phase when described by the cosine function?

Xu Heng, "The research is on the representation of the simple harmonic vibration image, and attention should be paid to the meaning of each point and the representation of the ordinate and abscissa."

Ling Yurou, "Thank you teacher."

Xu Heng, "Stop calling me teacher!"

Ling Yurou, "Good teacher! Follow the teacher!"

Xu Heng, "%￥#@￥..."

……

"This question, teacher."

Topic: It is known that the relationship between the thermoelectric electromotive force ε of the thermocouple and the temperature difference t is ε=αt, and the measured values ​​of ε and t are as follows.Try the difference-by-difference method to find the thermocouple thermoelectric coefficient. (no need to calculate error)

t (°C): , 40.0, 60.0, 80.0...160.0

ε（mV）：0.90、1.71、2.55、3.36……6.71

Xu Heng said directly, "Use the difference-by-difference method. It is estimated that you don't need to use the difference-by-difference method for this question. Even if you give the answer, you will get zero points."

"Don't you know this question? It's very simple...Sister, did you do it on purpose?"

Ling Yurou and the two girls were embarrassed and looked at each other.

Xu Heng, "???"

Afterwards, they asked Xu Heng less questions.

Unless it is really encountered no...

Ling Yurou, "Teacher...teacher..."

Xu Heng looked over.
