I Don’t Want to Win Lying Down

Xu Mang had only a look at a loss for Yang Xiaoman's magical operation. Would he die if he said that he bought the flowers? You must be mysterious, and you will be happy if you deliberately get angry. In other words... I seem to be this kind of person.

"..."

"I remember you wanted me to buy a car for you?" Xu Mang pretended to say indifferently: "When I make money, I will buy it for you."

"cut!"

"You stingy guy." Yang Xiaoman lay on Xu Mang and said disapprovingly: "Always use some reasons to fool me. Besides, the car I want to buy is quite expensive, and the money you earn from your paper may not be enough. ."

"Hey!"

Xu Mang suddenly hugged Xiaoman and said with a grin: "I am studying a material that can sell a lot of money."

Yang Xiaoman gave a blank look and said calmly: "I believe you a ghost, you **** is very bad."

"Really!"

"I am responsible for the research and development of a component material used in nuclear fusion energy reactors, and then they purchase." Xu Mang said proudly, "Am I awesome?"

Yang Xiaoman frowned and ruthlessly broke Xu Mang’s illusion: "Are you a theoretical physics, do you know what materials are? Many of your things are calculated by pure theory, but what you are facing now is the need. The product of the experiment, do you big fool know?"

Xu Mang shook his head: "I use the quantum database I just developed to calculate the possibility from a theoretical point of view. As for the experiment... others will do it."

"Humph!"

"Then what...can you teach me quantum mechanics?" Yang Xiaoman shrank into Xu Mang's arms and said squeaky: "I'm not recommended to graduate school, but I want to graduate soon. I'm currently Write a paper that uses quantum economics as the cornerstone to study the future of fission economy and fusion economy."

what?

What the hell?

Has economics started to involve quantum mechanics?

Xu Mang looked at Xiaoman in his arms with a confused look. He didn't even understand what quantum economics was, and the fission economy and fusion economy behind it were unheard of.

"What is quantum economy?" Xu Mang asked.

"Stupid!"

"This is the stock market option pricing model established by Scholes and won the Nobel Prize in Economics. Later, game theory experts launched the quantum economic model based on quantum economics." Yang Xiaoman explained: "This is the current The most avant-garde model."

Xu Mang still didn't understand, and asked curiously, "I still don't understand."

"It's normal for you to study and explore the laws of the quantity change of economic things." Yang Xiaoman raised his head and said silently: "From now on, set aside an hour every night to help me complete the thesis together. You are responsible for the quantum mechanics part."

"Oh..."

The next day,

Xu Mang got up at six o’clock in the morning, released Xiaoman’s grip, bought a little breakfast after putting on his underwear, and started his own work, establishing a systematic framework from the performance requirements, and proceeding according to this framework. Relative research.

According to the performance requirements, Xu Mang can infer that this part may not be a single material, and it needs a combination of multiple materials. A part composed of a connection process generally requires three materials, which meet the requirements of metal materials, composite insulating materials and external Insulation reinforcement materials, among which composite insulation materials must have relative mechanical performance requirements.

Immediately after,

Xu Mang made a table of performance parameters of metal materials and composite insulation materials, considering the comprehensive performance indicators from four perspectives: elastic modulus, shear modulus, shrinkage rate and Poisson's ratio.

"Ugh?"

"Why are you so early?" Yang Xiaoman glanced at Xu Mang and said with a slight dissatisfaction: "Don't make any noise, I don't have class today... Remember to order takeaway at noon."

"Ok."

Xu Mang responded casually, and continued his work.

With the performance parameters, the following is to plan the design standards of metal materials and composite insulation materials. According to the requirements of the documents, Xu Mang must first calculate the strength, yield stress, allowable stress, and layer thickness direction compression of the two materials. Strength, shear force...

but...

Xu Mang found himself stunned. Even though he has the ability to integrate the system, it already involves engineering knowledge. How to calculate the allowable stress?

Sorry...I don't even know the formula.

"It's over..."

"You must have a professional material science student who can help me calculate." Xu Mang thought for a moment. This student must have been in school for two and a half years, and he must know what to do, right, the minimum standard must be A member of the Fuda basketball team.

Walk to the balcony,

Xu Mang made a life-saving call to Liu Zhuo, a member of the former research team.

"Liu Zhuo?"

"Professor Xu...It's just past six o'clock?" Liu Zhuo's tone was full of helplessness when he received Xu Mang's call, and said, "Is there anything you want to do with me?"

"I remember you have been in school for two and a half years, right?" Xu Mang said with a smile: "I still remember that you formed the RAP band during your freshman year. You were the lead singer of the band and a member of the basketball school team?"

Liu Zhuo said, "Yes."

"do not talk!"

"Professor Xu needs you!" Xu Mang said seriously: "Come or not!"

Liu Zhuo smiled bitterly: "Professor Xu...I'm really busy these days."

"What are you up to?" Xu Mang asked.

"Busy in class." Liu Zhuo said, "I may not have enough credits."

"Don't panic!"

"The director of your department, Liu Guofang, director Liu, I have an old friendship with me." Xu Mang said with a smile, "As long as I speak, he won't let go, uh... I'll go to Liu later. The director asks you to come over and get some benefits from him by the way."

Liu Zhuo suddenly became interested, and hurriedly said: "Fuck, is Professor Xu really?"

"Remove the word "?", and the rest is true." Xu Mang said, "Do you know the formula for allowable stress?"

"know!"

...

Nine o'clock,

Xu Mang took the documents to the director's office in the materials department building.

"Hehe."

"Director Liu?" Xu Mang smiled and approached Director Liu. The professional smirk betrayed Xu Mang's purpose at the moment and said, "Is Director Liu busy?"

"..."

There is a legend circulating in Fuda, Xu Mang smiled, no good thing.

Director Liu looked at Xu Mang's professional smirk and was speechless for a while, and asked, "Very busy."

"Oh..."

"Director Liu, can you lend me someone?" Xu Mang asked.

"Who?"

"Liu Zhuo."

"Liu Zhuo?" Director Liu thought for a while, nodded and said, "Yeah."

Originally thought it would be a tug-of-war, but Director Liu just thought for a moment and agreed without asking. Xu Mang felt that there was only one reason to explain why. It is estimated that Director Liu did not know who Liu Zhuo was.

"Then what... Liu Zhuo doesn't have enough credits, can he be exempted this semester?" Xu Mang asked.

"Xu Mang?"

"You are too much!" Director Liu said with a black line on his face: "There is no such requirement as you."

Xu Mang expected that something like this would happen, so he took out a document and said to Director Liu: "Director Liu...This is a research project handed over to me by the International Nuclear Energy Agency. You must agree to it, otherwise you It will delay the happiness of all mankind."

I...

This...

Director Liu glanced at the cover of the document and didn't know what to say for a while.

"How did you get on line with this organization?" Director Liu asked.

"When I was in Nanda." Xu Mang said, "In short, I can only show you the cover. Some of the contents are confidential. I signed the contract. Director Liu...this exemption...how do you say? "

Director Liu reluctantly said: "It is impossible to exempt from the exam, but under reasonable conditions, you can make appropriate adjustments. You know what I mean?"

"understand!"

"Hey..."

After solving Liu Zhuo's problem, he called Liu Zhuo and told him the good news. Of course, in Xu Mang's narration, it was naturally an artistic rendering.

"Fuck!"

"Professor Xu... you are so awesome!" Liu Zhuo said excitedly after knowing that he had obtained the permission: "Are we really members of the International Nuclear Energy Agency?"

"Can this be fake?"

"I'm waiting for you in the old laboratory. This is the personal laboratory I applied for." Xu Mang said, "Hurry up, we have limited time!"

"Ok!"

moment,

Liu Zhuo came to the laboratory.

Xu Mang did not talk nonsense, and directly handed all the calculation problems to Liu Zhuo, and repeatedly emphasized confidentiality and accuracy, especially the accuracy, which was only 100% correct and no mistakes could be made.

"Professor Xu...This can't be wronged a bit too much." Liu Zhuo said with a worried expression: "I'm afraid that my ability is limited."

"There is no room for negotiation." Xu Mang said solemnly: "In short, you must make no mistakes. It is related to nuclear fission, so there is only success and no failure."

finally,

Liu Zhuo could only unconditionally agree to Xu Mang's request and began to calculate metal materials and composite insulation materials. Under Xu Mang's framework, Liu Zhuo had to calculate the six strengths of the two materials.

"Uh?"

"A formula?" Xu Mang stood by and watched for a long time, and found that Liu Zhuo was doing formulas. He said with a black face, "It's so simple?"

"Ok!"

"Not bad." Liu Zhuo said: "For example, the maximum equivalent and allowable stress of metal materials are determined according to the formula Sm=Min (2/3Sy, 1/3Su), where Sy and Su are the maximum yield stress and Maximum intensity."

"According to the performance index you gave, the maximum strength of the metal material at a temperature of 4.5K is 1440MPa, the yield stress is 450MPa, and the allowable stress is 300MPa..." Liu Zhuo continued: "At a temperature of 300K, the maximum strength is 500MPa , The yield stress is 170MPa..."

Paused,

Liu Zhuo said: "According to my understanding of materials, this metal material is generally nitrided 316 stainless steel."

"What about composite insulating materials?" Xu Mang asked.

"In the case of composite insulating materials... according to my calculations, it is probably a fiber reinforced composite material. This material is characterized by non-conductivity, high mechanical strength, and corrosion resistance." Liu Zhuo said: "There are many types of fiber reinforced composite materials. , But I prefer GFRP materials."

Xu Mang: 囧

Damn it!

Isn't this FRP?

People look for him thousands of Baidu. U U Reading www.uukanshu.com

Suddenly looking back, the person was there, dimly lit.

"Does it need to be modified?" Xu Mang asked: "It seems that the performance indicators of FRP do not meet the requirements?"

"correct!"

"It is not only the modification of FRP, but also the nitriding of 316 stainless steel. Otherwise, it is impossible to meet your performance index requirements based on the performance of raw materials." Liu Zhuo said seriously: "Professor Xu, your The performance index requirements still lack an important piece of information, as if you did not give a specific direction."

"For example, this elastic modulus lacks the thickness direction, axial direction and winding direction." Liu Zhuo said.

Xu Mang nodded: "Wait a minute, I will revise it again. Today Wednesday...this weekend, we two will research the materials. You will complete the modification. Are there any requirements for the software?"

"Have!"

"I hope that the quantum analysis software can have the function of fluid dynamics analysis." Liu Zhuo said embarrassedly: "Professor Xu...I know this requirement is a bit excessive, but one of your requirements is low temperature stress load. Air tightness..."

Xu Mang thought for a while, and calmly said: "This requirement is not excessive at all, this function will be available in the software tomorrow!"

Liu Zhuo:? ? ?

This...

determine?

Are you kidding me?
