"I thought what was going on... It turned out to be this thing. ”

"I won't allow you to do this in the future!"

Xu Mang said with a smile: "Of course I will help my dad get it, don't worry... In fact, ion implanters are not a big problem, and now I am not the same as I used to be, and many restricted technologies are not a problem at all. ”

Xiao Man heard Xu Mang personally say that he wanted to help solve it, and the original nervous emotions disappeared in an instant, and he said with a happy face: "Really?"

"Of course!"

"You're a third of my life. Xu Mang said with a smile: "Don't ask me where the remaining two-thirds went, it was taken away by your son and daughter, be fair... No one is more, no one is less. ”

“...”

"A quarter. Yang Xiaoman said with a smile: "Because in two years... A new member of our family may come, and when the time comes, they will have to share a little love from me and Yang Yang and Manman. ”

"No, you don't!"

"At that time, I was the father of three children, what else do I need you to do as a yellow-faced woman?" Xu Mang said with a smile: "You can go, the delivery person, let me live with the child, believe me... Yes, there are no problems at all, even if it doesn't... I'm looking for a long-legged stepmom for the kids. ”

Yang Xiaoman: (* ̄〈 ̄)

Damn it!

Is this bastard born with an aversion to the atmosphere?

It was such a warm moment, but it turned out to be disturbed by this big pig's trotters, damn it... Sure enough, I would rather believe that there are ghosts in this world than believe in the stinky mouth of men.

"Humph!"

"Boom... Come home and see what you do!" Yang Xiaoman said angrily: "Idiot... Shoot you!"

Xu Mang doesn't care about Xiao Man's threat at all now, he has used his life to test Xiao Man's bottom line, this woman is very stubborn in her mouth, but when it really comes to this point, her strength is still quite light, think about it... It seems that when I first met her, Xiao Man was the heaviest attacker.

That's really... Fight to the death, almost to the extent of flesh, but at that time, his ability to resist beating was also great, if Xiao Man is the same now as he was six years ago, he may not live tomorrow.

"Huh?"

"Do you like football more or basketball more?" Yang Xiaoman asked curiously: "Shall I accompany you to watch a ball game?"

"Of course it's football!" Xu Mang said seriously: "But just watch the ball... I can't go to some of the more chaotic occasions, so I'd better look at it at home... Prepare some beer, some fried chicken, and call three or five friends, that's good. ”

Speaking of friends,

Yang Xiaoman sighed: "Anyway, our high school reunion has not been held... It's a pity that everyone has entered the work and forgotten the past with each other? It's a pity, in fact, even if everyone enters the society, they still have to connect. ”

Xu Mang pursed his lips, he didn't know what to say for a while, in fact... There is a cruel fact, I'm afraid Xiao Man doesn't know that the high school reunion is held every year, and everyone is called, but he and Xiao Man are not called.

This can also understand why, no one can withstand such pressure, one is a world-famous scientist, and the other is a big capitalist, not to mention former classmates... Even if you are a person who is high in the eyes of others, in the eyes of yourself and Xiaoman... That's it.

"Actually..."

"There are high school reunions every year. Xu Mang smiled bitterly: "It's just that we didn't ask the couple to go, this is understandable, we put too much pressure on others, the class reunion should be happy, recalling the memories of the past, if the two of us are present, how can we recall?"

"But..."

"It seems that there are fewer and fewer people attending the class reunion, and it is almost impossible to hold it. Xu Mang restarted the car and said indifferently: "It is estimated that in a few years... Everyone forgot. ”

Words fall,

Xu Mang continued: "People will definitely be estranged from each other, everyone will meet 9 million people at this voice, 40,000 people will greet them, they will be familiar with 4,000 of them, get close to 300 people, and then finally forget in the sea of people." ”

"No way..."

"The world is too big, and our youth is limited, everyone has chosen to run to the distance, once with you and you side by side, after all, to say goodbye to you at a certain intersection. Xu Mang said, "But... It's not entirely about people, either. ”

"Now the development of science and technology has made an invisible gap between each other, you see... A mobile phone can keep us close at hand, everyone appears in the circle of friends, but disappears without a trace in life. ”

Yang Xiaoman especially agrees with her husband's point of view, in fact, the sense of distance between people is not entirely because of age, the progress of the times is also the culprit, technology makes everyone lost in the virtual, forgetting what real life is like.

...

Following

Professor Yuan Fei and his three colleagues had already left the magic capital, and Xu Mang was still asleep at that time, and when he knew about it, others had already boarded the plane, and finally he silently returned to bed and slept for a while.

But...

Once a person is awake, it is difficult to fall asleep, Xu Mang is holding his mobile phone and swiping a small video.

Then

Xiao Man walked in with his daughter in his arms, first ripped off the quilt, then opened the curtains, and the dazzling sunlight shone in, almost blinding the dog's eyes.

"Get up!"

"It's almost ten o'clock!" Yang Xiaoman kicked Xu Mang's ass hard, and said angrily: "Hurry up... Have you forgotten what I said last night?"

"Oh..."

Xu Mang hurriedly put on his clothes and pants, and then washed up briefly, he was going home today... I went back to Ning City to see my parents, I haven't been home for almost two or three months, I should go back for a few days, and if I don't go back, my parents will be killed.

After lunch,

The family of four went to Ning City, and this time they stayed for about five days.

meanwhile

Yuan Fei and three colleagues have arrived at HKUST, and they are greeted by the whole team. They heard that the solution they had received was beyond their imagination and could allow HKUST to lead the world in this field for 20 years.

Many people are a little skeptical about this, not questioning Xu Mang's strength, but feeling that there is a little exaggeration in this matter, how can it be twenty years... What is the concept of 20 years? At least two generations apart!

soon

In a conference room,

Professor Yuan Fei began to show the document in his hand, because there are too many contents, only part of the content can be displayed, such as the most concerned about reducing the bit error rate, according to the previous method, with HKUST's own optimization method, the error rate can be reduced by about double.

"The approach you see below may change your perception of this field. Professor Yuan Fei said seriously: "Academician Xu proposed a solution to the error rate, mainly in the satellite-ground synchronization technology to make breakthroughs. ”

Academician Xu called this technology adaptive optics technology ground rail communication. Professor Yuan Fei said seriously: "This technology uses a deformable mirror to correct the distortion of the wavefront of the light wave caused by atmospheric jitter, thereby improving the performance of the optical system. ”

"Through this technology, we can not only solve the problem of error rate, but also solve the problems of high-precision correction of atmospheric dynamic wavefront, coupling with high-efficiency spatial light to single-mode fiber, and wavefront interference of atmospheric backscattering under the same frequency transmission and reception. Professor Yuan Fei used projection equipment to show the content to everyone.

original

Many people still have a trace of doubt, but after seeing the content, that doubt has disappeared, and the only thing left is admiration, and Academician Xu can think of this kind of plan, using adaptive technology to solve the problem of bit error rate, and also solve the problem of reliability, and even solve the problem of duration afterward.

As per the previous optimization scheme, there is a big problem with its duration, because it is unstable... Now there's no need to think about it, adaptive technology works almost all the time.

That's awesome!

Why can't I think of such a solution?

"Wait!"

"The data above is perfect, and the tracking accuracy is better than the submicroarc metric... With efficient coupling, the average efficiency is more than 30 percent, but...", an expert at the scene frowned and said, "What about the equipment?"

"We don't have the technology to make such a high-end beam transmitter and the corresponding receiver. The expert said.

Hearing this question,

Everyone looked at Yuan Fei in unison, hoping that he would be able to explain this problem next.

At this time,

The two deans of the School of Astronomy and Space Science and the School of Physical Science of HKUST also quietly came to the conference room, and the two wanted to hear about the solution given by Academician Xu on the problem of thousand-kilometer quantum key distribution.

At the same time, I want to know,

How far is the gap between HKUST and the world's most powerful research institutes?

"Ahem!"

"The question... Academician Xu gave the answer. Professor Yuan Fei took out another document and said seriously: "This is about the equipment solution conceived by Academician Xu, in fact, it is not as complicated as you think, Academician Xu has carried out a transformation on our equipment..."

"But..."

"There's a whole new level of technical difficulty. Professor Yuan Fei said: "Academician Xu also solved it. ”

“？？？”

“？？？”

“？？？”

What's the situation?

This... Is this all solved?

Don't have any questions?

He... Why did he do this? These skills are enough to win a lot of honors, but he chose to give selflessly...

But...

Academician Xu no longer needs these honors to highlight his success, Academician Xu is more like the Dinghai Shenshen Needle of Huaguo, as long as he is in... The possibilities are endless.

"Isn't it shocking?"

Professor Yuan Fei showed a hint of a smile and said seriously, "I can tell you very complicated now... Academician Xu's greatness is beyond your imagination!"

Next

What Yuan Fei wants to show is the core content of this document.
