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

But can Shen Zhi answer?

Shen Zhi didn't study this major!

"Rocket engine..." Shen Zhi thought for a while, and then said,

The teacher listened carefully.

Although he doesn't understand rocket motor propellants.

But still nodded.

At this time, the classroom was very quiet.

Everyone listened quietly.

"I think there are pros and cons to both."

Although everyone can't understand.

But very interested.

At this time, outside the camera, Professor Zhou listened closely to the computer screen.

Waiting for Shen Zhi to say the reason.

Those who can put forward this point of view, most of them will then express their views and arguments that can support their views.

I saw Shen Zhi standing in the crowd with a tall and straight figure, with a calm expression.

The voice said in an unobtrusive manner, "First of all, liquid propellants are usually considered to be highly corrosive and dangerous, and generally need to be temporarily refilled before launch, otherwise it will be very troublesome to erect."

"Only the missile propellant tanks stored in the Soviet missile silos have a coating similar to glass bottles of injection medicine, which can be stored for a long time."

"As a result, he usually has too much preparation time and too many launch support systems."

Speaking of this, Shen Zhi knew that many people didn't understand, so he deliberately explained, "Because the propellant requires many tankers, pressurization equipment and so on, and there is a danger of leakage."

"Solids don't have these troubles. The volume is still small, and the density of solids is high, so the calorific value will be high."

Everyone understood in an instant.

Even students who don't know much about rocket engine propellant, after Shen Zhi's detailed explanation.

『_/ _source|source-group|.-』/-|_|『__/中_-transfer group--』/At this moment, I also understand.

According to what Shen Zhi said, it is better to be solid!

Why does Shen Zhi say that each has advantages and disadvantages?

All the students looked at Shen Zhi suspiciously.

Waiting for Shen Zhi to continue.

At this time, Shen Zhi changed the topic, and continued, "But, liquid has one advantage, that is, it can flexibly control the engine switch, which is beneficial to change the flight trajectory."

"Solid ones won't work. It is not easy to burn a grain many times. In addition, the solid propellant has a high technical content, so that the grain can burn evenly, and it is absolutely necessary to maintain the effective bonding between the grain and the engine casing." Difficulty."

Shen Zhi finished.

Even the students who didn't understand it suddenly realized it!

The teacher was slightly taken aback.

Not to mention whether what Shen Zhi said was right or not.

Such a large section of theory, as well as my own views.

Even if it is wrong, it is easy to convince everyone.

A message popped up on the teacher's phone.

He glanced down, and then asked, "??? Where are the solid propellants used?"

where?

A question that the teacher didn't say was asked in accordance with the professor's instructions.

Even he didn't understand many questions, so he could only repeat them verbatim.

The students were even more confused now.

These questions must be confusing for several non-major students.

Even for students who specialize in this major, it is a bit difficult.

Unless it is a scientific researcher!

Specialized in rocket engines!

Even the students can feel that the questions asked by the teacher standing on the stage are more detailed than each other!

(Got it) One is more difficult than the other!

The students all looked dumbfounded.

who am I?

where am I?

Is this an aircraft engine integration class?

Why are you asking these questions?

In fact, the teacher also thought about it, probably because he wanted to test Shen Zhi's knowledge reserve.

Then decide whether to believe what Shen Zhi said just now on the stage.

Although Shen Zhi didn't know why the teacher asked him a question that had nothing to do with this class.

But he didn't care.

For him, these questions are just basic knowledge about rocket engines.

"Solid propellant can be completely stored for a long time, and the preparation time required for launch is extremely short, so it is very suitable for the immediate response requirements of the military. Now it is actually mostly used by the military.

Unexpectedly!

Shen Zhi didn't just speak in detail.

I understand it very well! ?

Chapter 337 The whole classroom is boiling!

Although Shen Zhi stood in the crowd with a heroic spirit.

became the focus of the audience.

However, there is another problem!

That is, is Shen Zhi right?

When Shen Zhi's voice fell.

There was an uproar in the audience.

"Fuck..."

"Something!"

"It seems to make sense, but unfortunately I don't understand."

"Can anyone explain it?"

"Teacher, is Shen Zhi right?"

A classmate asked.

Suddenly, everyone turned their gazes to the teacher again in unison.

"This..." The teacher hesitated, and glanced down at the phone.

However, there was no news on the phone at this time.

"This..." the teacher faltered.

Attempt to procrastinate for a while.

But there was no news at all.

The dialogue with Professor Zhou still stuck on the previous question.

What's next?

Are you right?

But the teacher doesn't know either!

Continue to ask questions?

He doesn't even know!

The teacher even knows the most superficial level of rocket engine knowledge.

Where can I find questions and ask Shen Zhi to go!

After a while of entanglement in my heart.

The phone rang suddenly.

The teacher said happily, "Everyone, wait for me. I have a call. I want to answer it." After speaking, the teacher walked out of the classroom while answering the call.

"Professor Zhou, how about you calling me back?"

Professor Zhou's tone sounded very happy.

"Not bad! This young man is not bad! I think he may have more things hidden in his mind. These are just the tip of the iceberg. You see, when he faced these problems, he didn't even hesitate.

without hesitation,

Just a few seconds of thinking

The answer came out, it should be quite confident in myself. "

"The theory he said just now is really wonderful, many of which were not noticed by our researchers, and the advantages and disadvantages of solid and liquid states are also very complete. The more Professor Zhou talks later, the more excited his tone is.

Obviously he forgot that the other party taught aircraft engines, even though Professor Zhou was talking happily.

The teacher didn't understand either.

He could only nod repeatedly, and the professor echoed every word he said.

From the professor's reaction, he knew that Shen Zhi got the answer right!

Not only was the answer correct, but the answer originally conceived in the professor's mind was expanded to very detailed!

"I watched the live broadcast and the students seemed to be wondering whether what Shen Zhi said was right or not. Now you can go back to the classroom and tell the students that Shen Zhi is right."

"Okay, let's call if the professor has anything else to do, I'll hang up first..."

After the teacher finished speaking, he waited for the professor to finish his speech.

But unexpectedly, the professor immediately said, "Wait a minute, don't hang up, just keep on the call and enter the classroom."

"ah? "

The teacher was taken aback.

Obviously don't understand what this professor wants to do.

But still according to what he said, he walked into the classroom with the phone on hand.

I saw the blank expressions on the faces of the students.

Presumably everyone must still be puzzled by the question Shen Zhi answered just now, and they don't know whether it is right or not.

Thinking this way, the teacher followed the professor's instructions and said, "I know everyone is wondering whether what Shen Zhi said so much is correct."

When the teacher said this, he deliberately paused.

The students nodded firmly.

That's right, they don't know!

From the beginning to the end, the teacher did not say with certainty whether the questions Shen Zhi answered were right or wrong.
