For the change of structure, Xu Mang does not even need to carry out any experiments, and there are many useful data recorded in this research data, as long as reasonable deduction can be completed according to some of the above data.

Of course... Xu Mang will not miss this opportunity to learn, and from the entire material, he probably knows the research process of metamaterials, which is indeed very different from the tradition.

thermal insulation layer,

Inner liners...

Xu Mang glanced at the original design structure, from a highly dispersed solid material with a nanoporous network structure focused on each other and a gaseous dispersion medium filled with a gaseous dispersion medium in the void, which controlled the heat conduction and gaseous convective heat transfer of the material very well.

But... With an atmosphere less than one hundredth of Earth's and a surface atmospheric pressure of only 500 to 700 Pa, this design... To be honest, it has become a burden.

According to Xu Mang's calculations,

The adiabatic design of the newly structured aerogel not only provides ideal thermal insulation in a low-pressure environment, but most importantly, it can withstand the 60 gigabytes of impact during the launch phase and when it lands on the surface of Mars.

According to the general formula of Xu Yang structure, a set of data is obtained, and Xu Mang roughly obtains an ideal structure, which is honeycomb, but needs to be filled with some materials, and the material is a weakness of Xu Mang.

What kind of material should be filled in the honeycomb shape of aerogel to protect both the cold and hot ends?

At this point,

Xu Mang realized that in fact, the real difficulty is here!

Aerogel alone is not enough to achieve the desired properties, it must be a composite aerogel, similar to the metamaterials research laboratory, where aerogel is filled with highly dispersed solid materials.

"it!"

"What the hell should I do?" Xu Mang looked at the 3D model he had designed on the computer monitor, and was confused for a while, what does the aerogel of silica need to be filled?

However, this problem,

In the end, relying on the intelligent synthesis software of the material database, to solve the problem perfectly, at first Xu Mang was just trying his luck, assuming that he had obtained an aerogel in a theoretical state, but after analysis and simulation, the result was really a material.

resin

A special resin, if it is filled into the air raid of honeycomb aerogel, it is a very perfect protective effect at both the cold and hot ends, but because of this, it also involves new problems, and the support is gone.

No way

Xu Mang added graphite to the aerogel, accounting for 0.4 percent of the total.

"Solved!"

"Here's the airtightness!" Xu Mang stretched his waist, he couldn't think of such a simple question, he actually spent an hour and a half, picked up his mobile phone and glanced at the time, it was already half past ten, it was time to order a takeout.

Since living together, Xu Mang and Xiaoman rarely eat takeout, as long as the conditions allow, they will cook by themselves, but if they can't do it, they will drive to their father-in-law's house and come back with a meal.

Open the APP, Xu Mang was stunned by this dazzling store, and silently turned off the software, sometimes the violent airport is right, those takeaway platform software should be more intelligent, according to the daily nutrition report and the records of the previous order, deduce what to eat today.

Out

Xu Mang went to the nearby supermarket, bought noodles, drinks and ham sausages, and then returned to start boiling water, and during this boring time, Xu Mang made a phone call to Xiaoman.

"Hello?"

"Xiao Man... Have you eaten?" Xu Mang asked, "Do you want me to bring it to you?" scrambled eggs with tomatoes, fried broccoli with shrimp, stir-fried lettuce, with delicious Wuchang rice, and then a bowl of seaweed soup with shrimp skin on the side, what do you think?"

"Okay, okay!" Yang Xiaoman said happily: "Husband... You're so good to me, the food in the cafeteria has been unpalatable lately, and the price of pork has risen a lot... I'm hesitant to mention the company's food. ”

spent,

Yang Xiaoman hurriedly asked, "Husband... When will it be delivered?"

"Hey, hey..."

"I'm kidding 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... Besides, why hasn't my Pagani Fengshen sports car arrived in Hong Kong yet?"

"Roll !!"

Syllable!

Hung up directly,

Xu Mang looked at his phone with a confused face, not understanding why Xiao Man was so angry, but when Xu Mang started to make noodles, he found that he had been fooled, instant noodles were Kang Shibo, soda was Lei Bi, ham sausage was jade in jade, and all feelings were copycats!

Don't dare to eat...

If there is a problem with eating, it will be tragic to be sent to the ICU.

Twelve o'clock at noon,

Xu Mang came to Xiaoman's company, and then touched the canteen, and was caught by someone else just when he arrived at the door, and the key to catching Xu Mang was none other than Yang Xiaoman, who was blown up by gas before.

"Look at what, look!"

"Aren't you eating instant noodles?" Yang Xiaoman was still worried about the food delivery, and said angrily: "Why did you suddenly run to my company's canteen?"

"Don't mention it!"

"It's a disaster, I bought a total of three things, and all of them turned out to be fake. Xu Mang took out his mobile phone and showed Xiao Man the photos he took, what Kang Shibo, Lei Bi and Yu Zhongyu, almost laughed at the airport without violence.

"Well deserved!"

"That's the price to lie to me. Yang Xiaoman glared at Xu Mang, but after all, it was her husband, and the two of them both cooked and sat together for lunch.

This scene,

It makes many single women in the company envious.

"I think..."

"In the future, I will come to your company less. Xu Mang said solemnly: "You have too many single women here, and my arrival will affect the stability and unity within 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?"

"Hmm!"

Xu Mang nodded and said seriously: "Xiao Man... After mid-October, I may have to go to the capital to work for a while, you... What do you say?"

Hearing Xu Mang's words,

Yang Xiaoman suddenly stopped moving, looked at Xu Mang in surprise, and asked, "You... How long will it take?"

"About a month. ”

"It's not too long, but it's not over in a day or two. Xu Mang said helplessly: "I wanted to tell you before leaving, I think it's better to tell you now, you will know anyway." ”

Yang Xiaoman pouted, and said with a little dissatisfaction: "Then you have to be well-behaved in the capital, don't mess around outside, if I know... Don't blame me for being rude!"

Xu Mang shrank his head: "Don't worry, I've always been honest!"

I originally thought it was a stormy cry, but nothing happened, which made Xu Mang breathe a sigh of relief at that time, he couldn't see women crying the most, once he cried, he might be soft-hearted, and he wouldn't go.

After eating,

Saying goodbye to Xiao Man, Xu Mang returned home and continued to start the aerogel journey, according to his estimates, two hours at most.

...

Capital

Metamaterials Research Laboratory,

Professor Lu Jianping had just finished dealing with things when he received a call from the China Space Administration.

"Professor Lu?"

"How's the progress of the materials for that pneumatic reducer?" asked curiously, "I heard... You seem to be in some trouble that has caused the progress to stall, if that's the case, please work harder, the pneumatic reducer is very important in the whole process!"

"Secretary Tian. ”

"It's been a lot of trouble, but we've been working hard to overcome it. Professor Lu smiled bitterly: "If it is an ordinary aerogel, there is no pressure at all, and now many private enterprises are developing and selling aerogel, but aerogel in the aerospace field is controlled by Europe and the United States." ”

"It can be said that... We are completely locked down. "A lot of them are starting from scratch. ”

"I know your struggles... However, this pneumatic reducer is an indispensable part of the Mars program, and you are the only organization in China that can be studied, so you can't..." Isn't there any progress now?"

"Almost. ”

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

What the?

That... Others?

What's going on?

"Professor Lu?"

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

"Nope!"

"Just sent 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, a professor of theoretical physics at Fudan University." ”

Xu Mang?

He even knows how to do this?

The other party didn't believe it at all, Xu Mang... I know too well that the cooperation between the space agency and NASA on the exploration of the far side 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 there are many problems that he needs to solve.

"Professor Xu..."

"He... He even knows this?" asked the other party curiously.

"I don't know..."Professor Lu smiled bitterly: "But I am one thing sure, I will know the result tomorrow, according to Professor Xu Mang at that time, if it can be solved, it will only take a day, and it can't be solved... Not even for 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 definitely be a lot of problems, and when the time comes... You have to be careful and careful!"

It's not that Secretary Tian is cautious and doesn't trust Xu Mang, but... In just one day, the metamaterials research laboratory has been unable to solve the problem, and it is conceivable that there will be many problems in it.

"Don't worry!"

"Secretary Tian... We'll be careful when the time comes. Professor Tian said, "But... Don't take Professor Xu's words seriously, I guess he might be joking, if it can really be solved, it will take at least a week. ”
