Chapter 1343

It's not just Professor Stanley that's been shocked.

When director Li returned to Shangjing with the sample and helped Lu Zhou to register the patent ownership through the express channel, he sent it to the aviation science and technology group.

And almost the next morning when the samples were sent to the aviation science and technology group, Academician Yuan Huanmin rushed to the science and Engineering Bureau and found director Li's office.

"That SF-1 super fiber! Which unit did it come from? "

Staring at Academician Yuan standing at the door, chief Li's face was full of surprises no less than his.

If he remembers correctly.

The bag of samples should have been sent to the old academician yesterday afternoon

"Cough, first of all, have a drink of saliva and calm down," said director Li, looking at the Secretary standing in the office with the same surprised face and opening up, "Xiao Li, go and pour Academician Yuan a cup of tea."

"OK, OK."

Mu Mu nodded. Xiao Li, the Secretary, walked quickly to the cabinet with the electric kettle on the side, and soon put two cups of tea on the coffee table in the office.

Standing up from his desk, director Li took Academician Yuan to sit down on the sofa in front of the coffee table and explained.

"Some time ago, you asked me to ask academician Lu if you could get this thing out? I asked casually when I went to Jinling this time, and then he gave it to me. "

It's OK to hear the front part, but when hearing the back part, Academician Yuan Huanmin, who was drinking tea, almost didn't spray out the water he had just drunk.

"And then he gave it to you?" After swallowing a mouthful of tea, Academician Yuan's old face turned red, and his excited voice was filled with ignorance and disbelief, "what is it?"

Looking at his face, director Li could probably feel his mood, so he smiled bitterly.

"I know you are surprised, in fact I am more surprised than you. It's not five minutes since I asked him if he was sure to get it out, until he threw the finished product in front of me. You can imagine the expression on my face at that time It's probably more exaggerated than you are now. "

Leng Leng ground looks at the director Li that sits opposite, Academician Yuan nodded first, then shook head again.

If it was true, he could imagine director Li's surprise at that time, but what he couldn't imagine was how the land boat got this thing out in five minutes?!

"But how he is --"

"I know what you want to ask, but I don't know. I just heard that it's the method of computational materials to build models, and then the laboratory quickly verifies what Don't worry about it. Tell me first. Is it easy to use? "

"Just easy to use?" On the eager eyes, Academician Yuan shook his head with a smile and said with a slight sigh, "have you seen nylon rope?"

"Of course I have. What's the matter?"

"Replace the polyamide fiber twisted into nylon rope with the super fiber you gave me yesterday," said Academician Yuan in a serious tone when looking at director Li. "The tensile strength can be turned up at least a thousand times."

"A thousand times?!"

Frightened by the number, director Li's face could not help but slightly moved and asked.

"Yes, is there such an exaggeration?"

Looking at the moving look on the face of chief Li, Academician Yuan Huanmin shook his head.

"No exaggeration at all."

The young's modulus of nylon rope is about 1.4gpa, and the unit of the young's modulus of SF-1 super fiber has changed from GPa to TPA. Even considering the possible deviation caused by a series of factors such as technology, this statement is not exaggerated at all.

"It's no exaggeration to say that using this thing to make cloth or clothes is bulletproof clothing without ceramic lining. Use this thing as a rope, that's the anti pulling force of the aircraft carrier barrier rope level. We haven't tested other physical properties, but I can't imagine a stronger material in terms of tensile strength! "

"So awesome..."

"It's more than that," Yuan said with a sigh. "It's only our imagination that limits its use. I'm not sure..."

"Not sure?"

After indulging in his imagination for a while, he seemed to think that his idea was too exaggerated. Academician Yuan soon shook his head and denied his idea.

"No, that It's still a little too much. "

Being tickled by this guy's Guan Zi, director Li was in a hurry and asked.

"What's the exaggeration, you mean?"

Speaking in half, is this what people do?

It seems that his practice is a bit unethical. Academician Yuan Huanmin hesitated for a moment and finally said.

"What I want to say is, maybe even the space elevator..."

"It's possible, too!"……

As the saying goes, the more you know, the less imagination you have.

After all, scholars like Dyson are a few. With the increase of knowledge reserve and the increasing understanding of science, most people will gradually lose those seemingly unrealistic illusions about science.

It is quite strange for director Li to hear the word "space elevator" from yuan Huanmin, an old academician who has studied the space field for decades.

However, compared with the space station at Lagrange point and the scientific research station on Mars, this thing is a little beyond his imagination.

And no matter how surprised he is at the moment.

When Academician Yuan found his office, the whole material circle was shocked by a paper!

Water wood forum.

"Have you read that paper? It's the one that Lu Shen recently uploaded to arXiv! "

"No attention. We are engaged in material engineering. The research direction is not mathematics and physics. We are concerned about what his paper is for."

"What he sent was a paper on materials!"

"Lying trough?! Really? How long hasn't he studied the material? Didn't he go to study physics later? "

"Some time ago, he resigned as imcrc President Don't talk about it. Go and have a look. When our professor saw the paper just now, his jaw couldn't close in surprise! "

The title of the paper is so short that it can be read in two seconds.

However, the amount of information is not generally large!

Since the birth of computational materials, the theoretical calculation of complex systems has faced two challenges. One is how to transform the accurate theoretical treatment of micro level into the direct description of mesoscopic and macro level phenomena. The other is how to further improve the accuracy of density functional method, which is the basis of existing large-scale calculation.

However, the limitations of implicit functional density in describing van der Waals forces, metal bonds and other issues have always been a headache for researchers in computational materials.

But now this problem is actually solved by a paper on arXiv, so easily?

Everyone was shocked by the unexpected news.

And it's not just that!

What's more surprising is that the name on this paper is actually land boat!

From the last achievement to now, he has not been engaged in the research of material science for a long time, and many people can not remember clearly.

No one expected that he resigned from imcrc Council to pave the way for the return to materials science.

What's more, he just came back and did such an amazing thing

It's horrible!
