Variety show: The school's male gods, and the days when they were classmates with female stars

Because the classroom is relatively quiet.

Only the teacher's loud voice.

But when the teacher's voice stopped, he heard chattering in the middle and back row.

That's right, the chirping sound came from Shen Zhi, Hu Ge and Cheng Xiao!

The teacher squinted at them.

o

It's fine if you don't attend class, but you still chat!

Originally, Tong Lexin answered a difficult question for them, which made the teacher very happy.But after hearing the chirping voices of the three of them.

The teacher's mood suddenly became bad!

Coupled with today's cloudy day, the teacher's mood at this time is even more fueled!

"Shen Zhi!"

"Hugo!"

"Cheng Xiao!"

"What are you three talking about?"

Because the stars have come to Peking University for several months.

So the teacher memorized the names of a few stars (got it).

When their names were called, the whole person felt a chill down their backs.

Stand up abruptly.

This is indeed what they did wrong.

Talking when the teacher is lecturing not only disturbs the progress of the teacher's lecture, but also disrupts the good learning atmosphere of the students.

Cheng Xiao rolled his eyes, wanting to defend himself.

After thinking for a long time, she stammered, "We...we are discussing about study."

"Huh? Study?" The teacher raised his eyebrows, "What are you discussing about study?"

Cheng Xiao's eyes quickly searched for Ren.

Looking at the words on the courseware, she had an idea and said, "Engine!"

"Engine, ok, can any of you tell me my next question?"

"In order to successfully launch a rocket, the engine is indispensable, so what is the most important thing for a rocket engine?

Chapter 332 I Think You Are Wrong

The students were stunned.

rocket engine? !

Their class is about the integration of aircraft engines. Why did the teacher ask about rocket engines? !They never learned about rocket engines!

The students looked at the teacher suspiciously.

Seeing that some students wanted to speak, the teacher immediately said, "Everyone, don't remind them."

The students were stunned again, and then realized that the teacher didn't intend to test their "rocket engine" O

Instead, I want to test whether they are paying attention to the class.

If a star said that this class is about aircraft engines, then the teacher would definitely let them sit down.

At this moment, Cheng Xiao bit his red lips lightly, and looked at Hu Ge and Shen Zhi who were standing beside him.

Hu Ge also showed embarrassment.

He looked up at the teacher, then at the courseware.

At some point, the teacher turned off the courseware.

It seems that they are afraid that they will find out what this class is about.

Hu Ge scratched his head, full of doubts in his heart.

He remembered that the teacher asked a classmate to get up and answer the question related to aircraft engines.

Why did you change from an airplane to a rocket after you didn't attend class for a few minutes?

Could it be that this is a university classroom? 120

Just like when you were in high math class,

oa

Obviously, there are some basic knowledge in the front, and after a few minutes of slipping away, there are a bunch of incomprehensible formulas listed on the blackboard.

Nope!

They didn't attend the class at all, and they didn't know what the teacher was talking about!

Hu Ge and Cheng Xiao turned to look at Shen Zhi as if asking for help.

But then turned around again.

They occasionally listen to lectures and don't know how to answer.

Shen Zhi hasn't attended the class since the beginning of class, and definitely won't.

The audience who were watching the live broadcast also cheered up at this time.

I have to say that the trick of the teacher suddenly calling the star up to answer the question is very effective.

Even the audience didn't feel sleepy anymore.

Barrage area:

"The teacher talked about rockets so quickly? Didn't I hear you talking about aircraft engines just now?"

"Yes, just now I heard that it is also an aircraft engine, why did it suddenly become a rocket engine?"

"This class is the integration of aircraft engines. The teacher must be testing whether the stars are paying attention to the class. The teacher knows that even if he asks about the knowledge related to aircraft engines, the stars must not know, so there is such a question. Want to (ceae) see if they can find out."

"It turns out to be like this, high! Really high!"

"Hopefully they find out."

"But looking at the tangled faces of each of them, why does it feel like they must have not found it?"

At this time, Cheng Xiao and Hu Ge stood there with blank expressions.

Bingbing, who was sitting on the other side, reminded in a low voice, "Just now what the teacher talked about was an aircraft engine, not a rocket engine."

It's a pity that Bingbing is far away from them, and his voice is very small.

So they didn't hear it.

Just when the students thought they couldn't answer.

The teacher also shook his head, and was about to say something.

But at this moment, Shen Zhi suddenly said, "The most important thing is the working fluid.

The students were stunned for a moment, and all of them cast their eyes on Shen Zhi.

The teacher opened his mouth slightly and adjusted his glasses, "What?"

Shen Zhi calmly repeated his answer just now.

"To successfully launch a rocket, the most important thing in the engine is the gas working fluid."

The students are all science students, so they still know what gas is.

But they don't know anything about rocket engines!

Not to mention that this class is about aircraft engines.

It is not for everyone to build aircraft engines, but to understand.

So what everyone learns is superficial knowledge.

Even if you ask them what is the most important thing in the engine to successfully get the plane off the ground.

I'm afraid it's hard for them to tell!

After all, they are freshmen.

A lot of deeper knowledge has not been learned yet.

The classmate sitting next to Tong Lexin quietly asked, "Lexin, is Shen Zhi right?"

Tong Lexin frowned slightly and shook her head slightly.

"This... I don't know either."

With that said, Zhang Lexin smiled wryly.

They didn't learn rocket engines at all, how could they know!

The surrounding students gasped.

Zhang Lexin is recognized as a top student in the class.

If it is said that the students of Peking University are all Xueba, then Zhang Lexin is the Xueba among Xueba!

Even the schoolmaster Zhang Lexin didn't know about it.

They don't even know it!

The teacher was slightly taken aback. He just wanted to test whether the stars had attended the class, so he casually asked about the most important thing in the rocket engine.

He is talking about airplanes in this class, not rockets!

The teacher frowned slightly, and asked bravely, "Why is it a gas working medium? Why not a material?"

Although the teacher only teaches about aircraft engines, he still has a little understanding of rocket engines.

After all, rocket engines and aircraft engines still have similar principles.

So according to the principle, the teacher can not only understand a thing or two, but also tell some knowledge.

Since Shen Zhi continued to talk about this question, let him also talk about it!

The most important thing is gas working fluid?

Of course he knows what the working fluid is.

After all, he is a science teacher, and gas working fluid is not only used in the field of rocket engines.

The intermediary substance that can realize mutual conversion of thermal energy and mechanical energy is called working medium, such as water vapor.

But the most important thing in a rocket engine is the working fluid?

He doesn't think so!

The teacher shook his head, "Although I didn't intend to ask you this question, but since you answered it, let me express my opinion. I think what you said is wrong."

"As we all know, a rocket, also known as an injector, is a vehicle that uses ejected matter to create a reaction force to move forward."

"Rocket propulsion is a precise structure, and its principles are mainly mechanics, thermodynamics, and the application of other related sciences, such as electricity."

"The main difference between rockets and ordinary airplanes is that airplanes can only fly in the atmosphere, but rockets can work in outer space, because they don't need to use external air to burn and propelle..."

"If you want to successfully launch a rocket, the most important thing is the rocket engine, and the material of the engine is the most important. For example..."

"A rocket engine is like an inflated balloon. The material of the balloon exerts force on the gas in the balloon to compress it, forming a relatively high-pressure environment inside."

"When there is a hole to leak air, the gas will be accelerated by the pressure difference. It is propelled by the same reaction force as a rocket engine..."

"So I think the material is the most important thing."

"If you have an opinion, say it.".

Chapter 333 This answer is beyond the outline!
