Chapter 646: Must be serious (two/three)

For structural changes, Xu Mang does not even need to conduct any experiments. There are a lot of useful data recorded in this research material, which can be completed by reasonable derivation based on some of the above data.
Of course... Xu Mang will not miss this opportunity to learn. He probably knows the research process of metamaterials from the entire data, which is indeed very different from the traditional ones.
Insulation,
Airtight layer...
Xu Mang glanced at the original design structure. From the use of a nanoporous network structure focused on each other, and a highly dispersed solid material filled with a gaseous dispersion medium in the gap, the heat conduction and heat transfer of the material are well controlled. Convection heat transfer in gaseous state.
But... the atmosphere of Mars is less than one percent of the earth, and the surface pressure is only 500 to 700 Pa. This design... to be honest, it becomes a burden.
According to Xu Mang’s calculations,
The thermal insulation design of the new structure of aerogel not only provides ideal thermal insulation in low-pressure environments, but most importantly, it resists the 60G impact force that the aircraft will withstand during the launch phase and when it descends on the surface of Mars.
According to the general formula of Xu Yang's structure, a set of data was obtained. Xu Mang roughly obtained an ideal structure. This structure is honeycomb, but it needs to be filled with some materials, which is a weakness of Xu Mang.
What material is filled in the honeycomb of aerogel? Can it protect the cold and hot ends?
at this time,
Xu Mang realized that the real difficulty lies here!
Relying on aerogel alone is not enough to obtain the desired performance. It must be a composite aerogel, just like in a metamaterials research laboratory where aerogel is filled with highly dispersed solid materials.
"Fuck!"
"What do you do with this special?" Xu Mang looked at the 3D model he designed on the computer screen, and fell into confusion for a while. What exactly needs to be filled with silica aerogel?
However this problem,
In the end, relying on the intelligent synthesis software of the material database, it was a perfect solution. At first, Xu Mang was just trying his luck. He assumed that he had obtained an aerogel in a theoretical state. However, after analysis and simulation, the results really found a Kind of material.
Resin,
A special resin, if it is filled into the air raid of the honeycomb aerogel, it will have a very perfect protective effect on the cold and hot ends, but it also involves new problems, and the support is lost.
no way,
Xu Mang added graphite to the aerogel, accounting for 0.4% of the total.
"solve!"
"The following is airtight!" Xu Mang stretched out. He couldn't think of such a simple question. He actually spent an hour and a half. He picked up the phone and looked at the time. It was half past ten. It was time to order a takeaway. .
Since living together, Xu Mang and Xiaoman seldom eat takeaway. They cook by themselves as long as the conditions permit. If it is impossible, they drove to the old husband’s house and returned after a meal. From the feeling and convenience, Xu Mang hopes to keep going. , Because there is no need to wash dishes.
After opening the app, Xu Mang was stunned by the dazzling shop, and silently turned off the software. Sometimes Violent Airport was right. Those takeaway platform software should be smarter. According to the daily nutrition report and The record of the previous order deduce what to eat today.
Go out,
Xu Mang went to the nearby supermarket to buy a side bar, drinks and ham, and then returned to start boiling water. During this boring time, Xu Mang called Xiaoman.
"Hey?"
"Xiaoman... have you eaten?" Xu Mang asked, "Would you like me to bring you here? Tomato scrambled eggs, shrimp fried broccoli, fried lettuce, served with delicious Wuchang rice. Put another bowl of shrimp skin seaweed soup, what do you think?"
"Okay, okay!" Yang Xiaoman said happily, "husband...you are so kind to me, the food in the cafeteria is unpalatable recently, and the price of pork has increased a lot...I am hesitating to get the company Mention up on the food."
spent,
Yang Xiaoman hurriedly asked: "Husband...when will it be delivered?"
"Hey..."
"I am teasing you, I'm eating instant noodles, how can I cook for you, what do you want!" Xu Mang said with a smile: "The water has boiled... Let's talk about my Pagani Fengshen Why hasn't the sports car arrived yet?"
"roll!!!"
Snapped!
Hung up directly,
Xu Mang looked at the phone with a confused face, not understanding why Xiaoman was so angry, but when Xu Mang started instant noodles, he found himself fooled. The instant noodles were Kang Shibo, the soda was Lei Bi, and the ham sausage was Jade in jade, all the emotions is a copycat!
I can not eat it...
If something goes wrong, it would be a tragedy to be sent to the ICU.
at noon,
Xu Mang came to the bottom of Xiaoman's company, and then touched the cafeteria. He was caught by others just as soon as he arrived at the door. It was not someone else who caught Xu Mang, but Yang Xiaoman, who had been exploded before.
"What to look at!"
"Aren't you eating instant noodles?" Yang Xiaoman was still worrying about the food delivery, and said angrily: "Why did you suddenly run into the cafeteria of my company?"
"Don't mention it!"
"Misfortune does not come singly. I bought three items in total, but they were all counterfeit." Xu Mang took out his mobile phone and showed Xiaoman the photos he took. There was almost no violence like Kang Shibo, Lei Bi and Yuzhongyu. The airport was amused.
"Deserve it!"
"This is the price to lie to me." Yang Xiaoman glared at Xu Mang, but after all, it was his husband. The two had a meal and sat together for lunch.
This scene,
Many single women in the company are envious.
"I think..."
"I will come to your company less in the future." Xu Mang said solemnly: "You have too many single women here. My arrival will affect the stability and unity of your company, and it will also affect your rule."
"..."
"Idiot!" Yang Xiaoman said angrily: "Can you stop being so narcissistic? Didn't you go to school today?"
"Ok!"
Xu Mang nodded and said seriously: "Xiaoman...After mid-October, I may go to Beijing to work for a while, you...what do you say?"
Hearing Xu Mang's words,
Yang Xiaoman stopped suddenly, looked at Xu Mang with a look of surprise, and asked, "How long have you... been going?"
"About a month."
"Anyway, it won't be too long, but it won't end in a day or two." Xu Mang said helplessly: "I wanted to tell you before I leave. I think I should tell you now, anyway you will know."
Yang Xiaoman pouted, and said with a slight dissatisfaction: "Then you have to be good in Beijing, don't mess around outside, if you are known by me... don't blame me for being polite!"
Xu Mang shrank his head: "Don't worry, I've always been honest with you!"
Originally thought it was stormy crying, but nothing happened. Xu Mang was relieved at that time. He didn't see a woman crying the most. Once he shed tears, his heart might feel soft and he would not go. .
After eating,
Saying goodbye to Xiaoman, Xu Mang returned home and continued his aerogel journey. According to his estimation, it would be at most two hours.
...
Capital,
Metamaterials Research Laboratory,
Lu Jianping, Professor Lu just finished processing things, and then received a call from the China Space Administration.
"Professor Lu?"
"How is the material progress of that pneumatic reducer?" The other party asked curiously: "I heard...you seem to have encountered some troubles that caused the progress to be stagnant. If this is the case, please add more Force, pneumatic reducer is very important in the whole process!"
"Secretary Tian."
"We have indeed encountered a lot of trouble, but we have worked very hard to overcome this problem." Professor Lu smiled bitterly: "If it is an ordinary aerogel, there is no pressure at all. Now many private enterprises are developing and selling. Aerogels, but aerogels in the aerospace field are controlled by Europe and the United States."
"It can be said that we are completely blocked." Professor Lu said, "Many of them started from scratch."
"I know your difficulties...but this pneumatic reducer is an indispensable part of the Mars project. You are the only organization in China that can be researched. You can only..." The other party paused, then said: "Turn the pressure into Motivation, by the way... is there no progress now?"
"almost."
"But... we found someone else to solve this problem." Professor Lu said.
what?
Its... other people?
What's happening here?
"Professor Lu?"
"You didn't tell me about the space program, did you?" the other party asked in horror.
"No!"
"Just posted our research data, don't worry... he decided not to know." Professor Lu said seriously: "And this person can be trusted, he is Xu Mang, professor of theoretical physics at Fuda."
Xu Mang?
He even knows this field?
The other party didn’t believe it, Xu Mang...too much. The cooperation between the space agency and NASA on the exploration of the far side of the moon is based on Xu Mang’s arrival, and the space agency’s Mars program will invite Xu Mang to participate together. To this project.
after all,
Xu Mang is an authority in the field of astrophysics, and there are many problems he needs to solve.
"Professor Xu..."
"He... he even knows this?" the other party asked curiously.
"I don't know..." Professor Lu smiled bitterly: "But I'm a little bit sure that the result will be known tomorrow~EbookFREE.me~ According to Professor Xu Mang at the time, if it can be resolved, it only takes one day. It can’t be resolved...no ten days."
"..."
"one day?"
"Professor Tian, ​​if Professor Xu really solves the problem, please be sure to experiment carefully." The other party said solemnly: "If this problem is solved so quickly, there will be many problems. Then... you guys. Be careful and then careful!"
It's not that Secretary Tian is careful and doesn't trust Xu Mang, but... only one day has solved the problem that the metamaterials research laboratory has been unable to solve. It is conceivable that there will be many problems in it.
"Do not worry!"
"Secretary Tian...We will be very careful when the time comes." Professor Tian said: "But...don't take Professor Xu Mang's words seriously. I guess he might be joking. If it can be solved, it will take at least a week. time."
