Chapter 699

Today seems unusual,

director Guo found that although Xu mang was still one and a half hours late, he unexpectedly did not come to lunch. He asked the guard and was told that he did not see Xu mang leave. This shows that he has been staying in his office.

What's the situation?

Working? Too busy to eat lunch?

As for this assumption, director Guo only exists it in his fantasy, which is impossible...

at 4:30 in the afternoon,

director Guo sat in his office to deal with his business affairs. He glanced at his watch, sighed and said to himself, "it's almost... Xiao Xu is going to leave again. It's really a headache... I can't care, I can't say, You can't go back. "

Bang, bang, bang,

suddenly, there was a knock outside the door. After a call to come in, Xu mang came in with his bag on his back and a smile on his face.

"Hey, hey, hey."

"Director Guo?" Xu mang said with a smile, "are you busy?"

"..."

"is it Xiaoxu After seeing Xu Mang, director Guo couldn't help but breathe a sigh of relief and said: "I'm not busy. I haven't left yet? Don't you usually leave at four in the afternoon? It's been more than half an hour. "

"Cough!"

"Director Guo... Maybe you don't know about it yet." Xu mang sat on the opposite side, his expression was quite serious: "I go back so early, just to go to work earlier tomorrow. What do you think of this truth?"

Director Guo gave a bitter smile and said helplessly, "OK... I believe everything you say."

"How's the research going?" Director Guo asked curiously, "I remember yesterday that you said it could be solved in two days. It has been one day. How is the progress? I still know nothing about it. "

"Alas..."

Xu sighed, and his face was full of "sad urge". He said, "director Guo... I failed to live up to your expectations for me, and I also failed to live up to the expectations of the whole laboratory researchers, and even more than that of the whole country. In a word..."

hearing this, director Guo basically understood what he was going to say, and the big probability was research The tragedy of the project... He couldn't figure it out.

"I see."

"Let you study the material part of the missile engine by yourself. It's a bit... Overwhelming." Director Guo said seriously: "but Xiaoxu... There is one point I still want to say. Since you can't study it out, you should also say that... Don't use action to express your situation."

"Ah?"

"What did I say?" "Director Guo... I think there may be a misunderstanding between us, or the channel is not connected. We are not in the same frequency."

Director Guo Leng for a while, he also fell into confusion, said: "you are not research out, so abandon yourself, late all day, leave early?"

"No!"

"I did it one day before I was careful." Xu mang showed a smile, took out a stack of bound white paper from his bag, handed it to Director Guo, and said with a smile, "look, director Guo, this is the research result that I failed to live up to your expectations two days ago and finished one day ahead of schedule."

What?

He...

did he finish it ahead of time?

Director Guo took it to his hand in a panic, and quickly looked through the contents, not to mention... He flipped through it. It was not Xu Mang's graffiti. The handwriting was clear and concise, and contained a lot of calculation process.

Did he really study it?

As an expert in this field, director Guo is determined and intends to examine it carefully from the first page. Now there is still an hour to go before going off duty, which should be about one hour.

"Xiao Xu?"

"Or... You go back first?" "I'll give you a reply tomorrow," said Guo

"Ha ha."

"No hurry." Xu shook his head blankly and said indifferently, "you see, what problems do you have? We can solve them face to face."

"No problem!"

"I'll have to work hard for you." Director Guo nodded and began to review the research report. But only five minutes later, director Guo's eyes changed and his expression distorted.

All of a sudden,

director Guo raised his head and glared at Xu mang with horror on his face. He tried to speak, but he didn't know what to say. In short, there was no words to describe his inner emotions at this moment.

I have to say,

just what I just saw in five minutes has completely subverted my understanding of the whole world.

He...

How did he do it?

I didn't see him working hard. One day, he came to the door with a complete research report and said it was finished.What is this...

What's going on?

Suddenly,

director Guo thought of his old friend, Xu Mang's uncle, what he said to himself. Xiao Xu had such a working attitude. You don't need to pay attention to him and let him live and die on his own...

after reviewing this sentence again, he found that all the things he said fit Xu Mang's behavior perfectly. Is he such a lazy man Lazy work attitude? Doesn't it make sense for him to be late all day and leave early?

"Xu..."

"Xu mang?"

"Did you do it alone?" Director Guo asked solemnly. He changed his address to Xu Mang and called his name directly.

"Yes

"I spent a whole morning today, alas... I didn't even have lunch, so I was starving to death..." Xu said miserably, "I spent almost three and a half hours on these 70 pieces of content, and my hand almost didn't break."

"..."

director Guo didn't say anything. He didn't believe that this research report was completed today, and it only took three and a half hours. However, he didn't want to go into too much research. When he finished, he was finished. He could do whatever he wanted. The more questions he asked, the more doubts he would have.

When director Guo continued to go deep into this research report, he gradually found that he could not keep up with the contents. As an expert in this field, he had already felt confused about some contents.

Carbon fiber reinforced silicon carbide composites?

According to Xu Mang's research results, carbon fiber reinforced silicon carbide composite has the advantages of low density, high strength specific modulus, large damage limit, extreme high temperature resistance, good oxidation resistance and strong corrosion resistance.

As he continued to read,

director Guo saw the research on active cooling structure, and then he realized that this research report was really not simple!

Carbon fiber reinforced silicon carbide composites can only be used once, and the time is very short, only half an hour. If you want to have a longer time, or even reuse, it must be combined with active cooling structure.

This aspect has been put forward by the laboratory, but it is too difficult. In addition, the laboratory has not finished the material, so it directly gives up the idea of combining material and cooling structure.

But...

I didn't expect that Xu mang raised it again today.

Wait a minute...

something's wrong!

There was no active cooling structure in the information given to him. How did he know?

"Xiao Xu?"

"You... You tell me the truth... How do you know about active cooling structures?" Director Guo asked, "did someone tell you?"

"No!"

"I thought of it myself." Xu mang said with a smile: "under my calculation, the service limit of carbon fiber reinforced silicon carbide composite is half an hour. If it exceeds half an hour, various conditions will appear. After all, the material also has a life span."

"In this case, I'm thinking... How to increase the service life in other ways without improving the performance of the material?" "I thought about the cooling method of carbon fiber reinforced silicon carbide composite and metal combination," Xu said

Genius!

What a genius!

Director Guo looks at Xu mang seriously. He doesn't know the young man in front of him. Do you think he is lazy? That's really lazy... Late to leave early, casual, you say he is diligent? It was really hard work, and all of a sudden he finished the project.

When his eyes returned to the research report, director Guo found that Xu mang actually provided two kinds of structures. The first was the combination of materials and metals, and the second was the cooling structure of all composite materials. Both of them had their own advantages.

saw here, director

Guo closed up the binding Research Report, and said seriously: "Xiao Xu, I will give you an answer tomorrow. Such a big thing is not my has the final say, we are only responsible for the study of the scramjet engine, and we should discuss with his department."

"Oh..."

after thinking for a moment, Xu mang said cautiously, "can I leave the laboratory first? Call me if you have any questions... I didn't mean to escape, because NASA still needs me. You should know what I'm going to do. "

Xu pointed to the tip of his finger.

"Mars!" Xu said.

Director Guo looked at Xu mang with a full face of shock, which lasted for a minute, and then asked incredulously, "Xiao Xu... How many research projects have you received?"

"Two."

"One is the material and thermal balance of the scramjet here, and the other is NASA's Mars program." Xu mang spread out his hands and said innocently, "I'm going to receive the prize in December. You know... Get the Nobel Prize in physics.""..."

"hard work for you." Director Guo returned to his senses and said with a wry smile: "the greater the ability, the greater the responsibility. Xu Mang, don't come tomorrow. I'll call you and tell you the result of the discussion. Then, I'll talk about the specific things to be modified."

"Oh..."

Xu mang nodded and was ready to get up and go home. As soon as he came to the door, he suddenly stopped and said to Director Guo who was reading his research report: "by the way, director Guo, I have a gift for you."

Gifts?

What gift?

Director Guo looked at Xu mang curiously.

"Here you are

"This is the gift." Xu mang took out another stack of bound white paper from his satchel, put it on the table, and then said, "I'm leaving..."

the words fell, and

left the office directly, leaving director Guo alone confused.

Director Guo took the so-called "gift" and fell into a state of panic the next second.

This is...

this is too advanced?!
