Chapter 646

For the structural change, Xu does not even need to carry out any experiments. There are many useful data recorded in this research data, which can be completed by reasonable derivation based on the above data.

Of course... Xu mang won't miss this opportunity to learn. From the whole material, he probably knows the research process of metamaterials, which is quite different from the tradition.

The insulation layer,

the air tight layer...

Xu took a look at the original design structure, from the use of mutual focusing nano porous network structure, and filled with gas dispersion medium in the gap of a highly dispersed solid material, so it is very good control of the material heat conduction and gas convection heat transfer.

But... The atmosphere of Mars is less than one percent of the earth's, and the surface atmospheric pressure is only 500 to 700 Pa. this design, in fact, has become a burden.

according to Xu Mang's calculation, the adiabatic design of

's new aerogel not only provides ideal adiabatic effect under low pressure environment, but most importantly, it resists the impact force of sixty G when the launch phase and the surface of Mars arrive.

According to the general formula of Xuyang structure, a group of data are obtained. Xu mang has an ideal structure, which is honeycomb, but needs to be filled with some materials, and the material is a weak rib of Xu mang. What material does

fill in the honeycomb of aerogels? In order to protect both cold and hot ends?

At this time,

Xu mangcai realized that the real difficulty lies here!

is not enough for aerogels to obtain desired properties. It must be a composite aerogel, similar to the high dispersion solid material filled in aerogels in the metamaterial research laboratory.

"Lying trough!"

"What can I do with that?" Xu Mang looked at the 3D model he designed on the computer screen, and was in a fog for a long time. What does the aerogel of silicon dioxide need to fill?

however,

finally solved the problem perfectly by the intelligent synthesis software of the material database. At first, Xu ran just took a chance and assumed that he had obtained a theoretical aerogel. However, after analyzing and simulating, he found a material.

resin,

, is a special resin. If it is filled into the void of honeycomb aerogels, it will protect the gas from the perfect cold and hot ends.

couldn't help it.

Xu ran added graphite to aerogel, accounting for zero point four percent of the total.

"Solve it!"

"Below is the air tight!" Xu mang stretched himself for a long time. He didn't think of such a simple problem. He even spent an hour and a half picking up his mobile phone to take a look at the time. It was already 10:30, and it was time to order a takeout.

Since they lived together, Xu Mang and Xiaoman seldom eat takeout. They cook their own food as long as conditions permit. If they can't, they drive to the old father-in-law's house and rub a meal back. From the emotional and convenient level, Xu mang hopes to go all the time, because there is no need to wash the dishes.

After opening the app, Xu mang is forced by the dazzling shop and turns off the software silently. Sometimes the violent airport is right. The software of the takeaway platform should be more intelligent. According to the daily nutrition report and the records of the previous points, we can deduce what we should eat today.

After going out,

Xu mang went to the nearby supermarket, bought instant noodles, drinks and ham sausage, and then returned to boiling water. During this boring period, Xu gave Xiao man a call.

"Hello?"

"Xiaoman... Have you eaten yet?" "Do you want me to send it to you?" Xu asked? What do you think of scrambled eggs with tomato, fried broccoli with shrimps, and lettuce with delicious Wuchang rice, and then a bowl of shrimp skin and laver soup on the side

"Good, good!" Yang Xiaoman said happily: "husband... You are so kind to me. The food in the canteen is terrible recently. The price of pork has gone up, and many of them have gone up. I am hesitating to raise the company's food."

As a result,

Yang Xiaoman asked in a hurry: "when will my husband deliver it?"

"Haha..."

"I'm teasing you. I'm eating instant noodles. How can I cook for you? What do you think?" Xu mang said with a smile: "the water has been boiled... Don't say, how come my Pagani Fengshen sports car hasn't arrived in Hong Kong yet?"

"Get out of here!"

Bang!

Xu mang looks at his mobile phone with a confused face and doesn't understand why Xiaoman is so angry. However, when Xu mang starts to make noodles, he finds that he has been cheated. Instant noodles are Kang Shibo, soda is leibi, ham sausage is yuzhongyu. His feelings are all special. He is a fake product!

Dare not eat...

in case of eating problems, it would be a tragedy to send them to ICU.

At 12:00 p.m.

Xu mang came to the bottom of Xiaoman's company and touched the canteen. As soon as he arrived at the door, he was caught by someone else. It was Yang Xiaoman who had been blown up by gas."What are you looking at?"

"Don't you eat instant noodles?" Yang Xiaoman is still worried about the delivery of food. He said angrily, "how did you suddenly run to the canteen of our company?"

"Don't mention it!"

"It never rains but it pours. I bought three things in total and all of them were fake." Xu mang takes out his mobile phone and shows Xiaoman the photos he has taken, such as Kang Shibo, leibi and yuzhongyu. There is almost no violent airport to laugh at.

"You deserve it!"

"That's the price of deceiving me." Yang Xiaoman glared at Xu Mang, but it was his husband after all. They both had a meal and sat together for lunch.

This scene,

has been envied by many single women in the company.

"I think..."

"you should come to your company less in the future." Xu mang solemnly said: "you have too many single women here. My arrival will affect the stability and unity within your company, and will also affect your rule."

"..."

"idiot!" Yang Xiaoman said angrily, "can't you be so narcissistic? Didn't you go to school today

"Well!"

Xu mang nodded and said seriously: "Xiaoman... After the middle of October, I may go to work in Beijing for a period of time. What do you say?"

Hearing Xu Mang's words,

Yang Xiaoman suddenly stopped, looked at Xu Mang in surprise and asked, "how long have you been

"About a month."

"It won't be too long, but it won't be over in a day or two." Xu mang helplessly said: "originally wanted to tell you before leaving, I think I'd better tell you now, anyway you will know."

Yang Xiaoman Du mouth, slightly dissatisfied said: "then you in the capital to be good, don't mess around outside, if I know... Don't blame me for being rude!"

Xu mang shrunk his head: "don't worry, I've always been honest and friendly."

Originally thought it was like a storm of tears, but nothing happened, so Xu mang breathed a sigh of relief. He couldn't see a woman's tears most. Once he shed tears, he might feel a soft heart and stop going.

after dinner,

bid farewell to Xiaoman. Xu ran back to his home and continued to open the aerogel trip, at most two hours.

...

Beijing,

metamaterials research laboratory,

Professor Lu Jianping has just finished the work, and then received a call from the China Space Administration.

"Professor Lu?"

"How about the material progress of the pneumatic reducer?" The other side asked curiously, "I heard that... You seem to have encountered some trouble, which has led to the stagnation of the progress. If so, please increase the strength. The pneumatic reducer is very important in the whole process."

"Secretary Tian."

"It's a lot of trouble, but we've been working hard to break it." Professor Lu complained with a bitter smile: "if it is a common aerogel, it is not what pressure is. Now many private enterprises are developing and selling aerogels, but aerogels in aerospace field are controlled by the European and American authorities."

"It can be said that... We are completely blocked." "A lot of them start from scratch," Professor Lu said

"I know your difficulties... But this pneumatic reducer is an indispensable part of the Mars program. You are the only organization in China that can study it. They can only..." the other party pauses and then says, "turn the pressure into power. Say... Is there no progress now?"

"Almost."

"But... We found someone else to solve the problem." Professor Lu said.

What?

Other people?

What's the situation?

"Professor Lu?"

"You didn't tell me about the space program, did you?" Asked the other in horror.

"No!"

"We just sent our research data, don't worry... He didn't know." Professor Lu said seriously: "and this person is trustworthy, he is Xu Mang, Professor of theoretical physics at Fuda University."

Xu mang?

He even knows this field?

Xu mang... Too well understood, the cooperation between NASA and NASA on the exploration of the back of the moon is based on Xu Mang, and the space agency's Mars program will invite Xu mang to participate in this project one day.

After all,

Xu mang is an authority in the field of astrophysics, and he needs to solve many problems.

"Professor Xu..."

"he... He can even do this?" Asked the other party curiously.

"I don't know..." Professor Lu said with a wry smile, "but I'm sure that the result will be known tomorrow. According to Professor Xu mang at that time, if it can be solved, it will only take one day, if it can't be solved... It won't work for ten days.""..."

"one day?"

"Professor Tian, if Professor Xu really solves the problem, please make sure you experiment carefully." The other side said solemnly, "if you solve this problem so quickly, there will be more problems. Then... You should be careful and careful."

It's not that Secretary Tian is cautious and distrustful of Xu Mang, but that he has solved the problems that metamaterials research laboratory has been unable to solve in just one day. It is conceivable that there will be many problems in it.

"Don't worry."

"Secretary Tian... We will be very careful." "But... Don't take Professor Xu's words seriously. I guess he may be joking. If it can be solved, it will take at least a week."
