Chapter 699: The Base Where People Are Restless

Light and shadow interweave, and time flies by.

In the blink of an eye, time passes by in the painting of time.

Suddenly.

Leaves fall, and the cold autumn bids farewell to the stage of the four seasons.

Instead, the winter snow covers the earth, and the snowflakes flutter, as if the whole world is silent.

But this is just an appearance.

In the vast land of China, there are still people who are working hard to break the ice after winter in the face of wind, snow and stars.

"Consultant Xu, you have worked hard today."

221 Base.

Second Branch.

Outside a small building that looks ordinary.

A middle-aged man in his forties was smiling and holding Xu Yun's hand, and enthusiastically said to him and Lao Guo beside him:

"Consultant Xu, you have solved another difficult problem for us."

"This time, thanks to you, if it weren't for you, our project team would probably be stuck for a while."

Xu Yun hurriedly shook his head and lowered his posture:

"Professor Li, you are too kind, I just did some insignificant work."

"I am younger than everyone else, and my thinking is more jumpy, so I was just lucky to think of some ideas that everyone didn't notice. I'm afraid you will dislike me for not being stable enough."

"It is the comrades in the project team who really verified the feasibility of the ideas and put them into application technology. I dare not take the credit."

The middle-aged man smiled and said nothing.

If Xu Yun can only solve the problems of various project teams once or twice occasionally, then it may be related to his active thinking.

But as far as he knows,

Xu Yun has solved more than dozens of problems for various project teams, with a success rate of nearly 80%. This cannot be explained by "jumping thinking".

Now, because Xu Yun's image of sitting in a wheelchair is somewhat similar to Zhuge Kongming, and he spends most of his time lying in bed every day, the nickname "Mr. Lying Donkey" has begun to spread in the base.

And opposite the middle-aged man.

Looking at the middle-aged man's expression of "I'm a fool to believe you", Xu Yun couldn't help shaking his head in his heart.

He is really fake.

Yes, so far he has given reasonable and appropriate answers to the problems encountered by many project teams, but these answers are basically irrelevant to Xu Yun's own professional knowledge-after all, he is not engaged in nuclear engineering.

These answers of his are either based on some intersections in related fields, or directly applied to the future achievements of some big guys in the project team.

In short, he is a ctrl+c and ctrl+v.

For example, the matter of the middle-aged man's project team today.

This middle-aged man is called Li Hengde. He graduated from the University of Pennsylvania across the sea. He is now a professor at Shuimu University, a future academician of the Chinese Academy of Engineering, and a top nuclear material expert.

Li Hengde's team is a new member transferred to the base after the [Sanqing] project, and arrived in the same batch as Lou Zhicen, Tu Luming and others.

At present, there are 9 project team members in the 221 base (excluding production workers), mainly responsible for the research and development of zirconium alloy cladding tubes.

Zirconium alloy cladding tubes are an important structure of nuclear reactors. They don't play a big role in atomic bombs, but they are quite special in the detonation process of hydrogen bombs.

The reason why it is special is mainly because zirconium alloy cladding tubes belong to a relatively mediocre structure, and the definition is somewhat vague.

That is, it must be there, but the technology does not need to be advanced.

It is roughly similar to the power supply in later computer accessories.

Haiyun Zhenhua's head power supply is good, but if you really want to compress the configuration, you can make do with anything like Xianma and Jinhetian.

But on the other hand,

You can keep reducing the brand and price of the power supply, but no matter how you cut the budget, you can't do without power supply.

So the task of Li Hengde's team is to at least make a beggar version of zirconium alloy cladding tube.

Li Hengde started working the next day after arriving at the base, but soon they found a problem in the research and development process:

Zirconium has comprehensive excellent properties such as small thermal neutron absorption cross section, good mechanical properties, high temperature resistance, and good corrosion resistance, but it is easy to cause brittle fracture due to hydroxide orientation.

Because in nuclear reactions.

Zirconium alloys will be bombarded by fast neutron flux, which will cause radiation damage to zirconium alloys.

The radiation damage of alloys is mainly due to the elastic interaction between fast neutrons and alloy atoms, which makes alloy atoms leave their lattice positions and produce point defects without changing the target atoms.

At the same time, zirconium alloys have a great affinity with hydrogen and are easy to form hydrides, especially at high temperatures, hydrogen is more likely to diffuse into zirconium alloys, which affects the mechanical properties of zirconium alloys.

After reaching a certain situation, zirconium alloys will suffer brittle fracture.

For those who cannot understand this sentence, imagine that when you are hard to a certain extent, it suddenly breaks into two pieces.

This problem troubled Li Hengde and his team for a whole week. After they determined that they could not solve it within the group, they sent a request for assistance to the advisory group.

This is why Xu Yun was here today.

It was a coincidence.

Although Xu Yun had no professional connection with reactors, he did know something about zirconium alloy cladding tubes.

Because this material involves the radiation effect of charged particle beams, it belongs to the category related to particle physics - but what Xu Yun was exposed to at that time was no longer zirconium, but other materials that he didn't know if he could talk about, so he didn't talk about it.

However, zirconium alloy cladding pipes are still used in the field of nuclear reactors, and Xu Yun has more or less come into contact with its structural information.

So he told Li Hengde what he understood:

Starting from the Q value of rolling processing, that is, the ratio of wall reduction to diameter reduction, the annealing system and secondary annealing are introduced. At the same time, based on density functional theory, the hydrogen atoms are located in the crystals of α, β-Zr and Zr-M intermediate metals. grid position to obtain the specific dissolution enthalpy.

After calculation by Li Hengde's team, this idea finally solved the problem successfully.

What's even more coincidental is that.

The person who will solve the problem of brittle fracture caused by the hydroxide orientation of zirconium alloy cladding pipes in the future is actually Li Hengde in front of Xu Yun

So in the face of Li Hengde's praise, Xu Yun was really a little embarrassed - it was equivalent to you traveling back ten years and publishing "The Lord of Best Friends" based on your memory, and then one day you found Cuttlefish praising the book in the comment area. I even gave you a reward

Then Xu Yun scratched his hair shyly and said to Li Hengde:

"Professor Li, please stop being polite. We are all doing our best for the country."

"If the project team encounters any problems in the future, they are welcome to come to the workers' hospital to see me. As long as I don't go to places like Lop Nur or Qinghai Lake, I guarantee that I will arrive within an hour!"

Xu Yun's promise to Li Hengde only included time, and did not say anything about "I promise to solve this problem".

It's the same truth as before. After all, Xu Yun is not a practitioner of nuclear engineering.

Although his success rate in solving problems during the past period was close to 80%, in other words, he still had about 20% of the problems that he could not solve.

Later, these problems were either solved by other experts, or they were still stuck there and were slowly pushed forward by the responsible comrades.

This is a situation that cannot be solved by human power. It is like an ordinary person being reborn into the past. You may have the future economic and political situation at your fingertips, but asking you to develop chip architecture and so on is obviously a bit difficult.

Then Xu Yun looked at the time and felt that it was almost time, so he was about to turn around and say goodbye to Lao Guo.

But before he spoke, a weak voice sounded next to Li Hengde:

"Consultant Xu, can I ask you a question?"

Xu Yun was stunned for a moment and turned to look at the speaker.

The person who spoke was a young man in his early twenties, with average looks, but a very high hairline—probably enough to compete with future generations of Penguin T3 programmers.

Xu Yun remembered that the other party was called Wang Aimin, a very common name in this era.

Wang Aimin is a mathematics student with strong writing skills. He left a pretty good impression on Xu Yun in the past two days.

When Xu Yun saw this, he smiled at him and temporarily gave up the idea of ​​leaving:

"Comrade Aimin, if you have anything to say, just say it."

Wang Aimin glanced at Li Hengde after hearing this, and asked after getting Li Hengde's permission:

"Consultant Xu, if I remember correctly, it will be New Year's Eve in about ten days, right?"

A surprise suddenly appeared in Xu Yun's eyes.

He thought Wang Aimin wanted to ask some technical questions, but he didn't expect that what he cared about was the time of the Spring Festival?

All classmates who are Chinese in this life should know this.

As the first of the four traditional Chinese festivals, the Spring Festival means far more to the Chinese nation than all other festivals.

The origin of the Spring Festival can be traced back to more than 2,000 years ago.

At that time, the ancients combined the time concept of the heavenly stems and earthly branches and determined the sixty-year cycle, and the first month of the year was the first month.

The first day of the first lunar month is called the beginning of the year, which is the beginning of the year. It is also called "Sui" at that time.

In ancient times, the word "Nian" was placed in Hebu. "Shuowen, Hebu" records: "Nian means that the grain is ripe."

It indicates that the weather will be smooth, the seedlings will be strong, and the grain will be abundant.

Since grains generally ripen once a year, "Nian" was extended to the name of the year.

Of course.

The word "Spring Festival" has different specific meanings in different historical periods.

For example, in the Xia Dynasty, the Spring Festival was set on the first day of the first lunar month, while in the Shang Dynasty, it was called "Si" and was set on the first day of the twelfth lunar month.

In the Zhou Dynasty, it was the first day of November, and in the Qin Dynasty, it was the first day of October.

During the Han Dynasty, people also called the first of the twenty-four solar terms the Spring Festival as the Spring Festival.

After the founding of New China.

The first plenary session passed the Gregorian Calendar Law, which designated January 1 of the Gregorian calendar as New Year's Day and the first month of the first lunar month as the Spring Festival.

That's right.

The Spring Festival that everyone is celebrating now - here refers to the specific definition of time rather than the concept of the festival, was only born more than 70 years ago.

The long history of Chinese civilization has also brought many "fan stories" to the Spring Festival.

For example, there are happy Nian beasts, peach charms, firecrackers, etc.

There are also sad things like not having a holiday on New Year’s Eve, online writers coding on New Year’s Eve for three consecutive years, etc.

But overall.

No matter how much the appointment criticizes the new year as having lost its flavor, in the era when Xu Yun traveled back in time, the Spring Festival was still a festival that held a special place in the hearts of Chinese people.

But in this period, especially in the 221 base, the Spring Festival is not so exciting and exciting.

no way.

The country is poor.

On a special day like New Year's Eve, you can only nibble on the steamed buns and drink a few sips of oily soup. The north wind is blowing and the snow is flying outside, which will only make everyone more sentimental.

Xu Yun has experienced this before.

In 20 years, his grandparents were both hospitalized during the Spring Festival. Xu Yun's father also caught a cold. Xu Yun's cousin was unwilling to return to his hometown because he lost his job, so Xu Yun's uncle stopped coming to celebrate the Spring Festival.

On New Year's Day, Xu Yun's mother cooked some porridge, and then had a New Year's Eve dinner with pickled mustard and spicy wings bought from the KFC downstairs that was still open.

Although several things were successfully resolved in the end, Xu Yun will never forget the emotion he felt while eating that meal.

This will still be the case in future generations, let alone this period.

Could it be that the winter wheat incident made Wang Aimin want to have a full meal?

But soon.

Xu Yun understood why Wang Aimin was so excited - because Wang Aimin spoke again:

"Consultant Xu, I heard that our base will be making beef and mutton dumplings during the Spring Festival this year. Can everyone make them?"

Xu Yun raised his eyebrows subconsciously when he heard this, turned to look at Lao Guo beside him, and whispered to him:

"Guo Gong, how did this news get out?"

To know.

The making of dumplings during the Chinese New Year is only known to the base management, and it has not been made public for the time being.

Unexpectedly, Wang Aimin, an ordinary base researcher, would speak out about this matter - and judging from Li Hengde's expression, he probably knew about it.

Lao Guo shrugged at him and said in a helpless tone:

"It's so new. There are so many people in the base. Unless it's a political mission, what can't be spread?"

"For example, the placement of cattle and sheep requires the cooperation of the transportation team and the sideline team. During the transportation, there are other employees commuting to and from work. Why don't you ask a few questions when you see so many cattle?"

"Also, for example, the leaders of the base all have wives, right? If a young couple mentions this non-confidential matter after a night out, someone's wife might reveal it at work the next day - oh, I forgot, You don’t have a wife and you don’t have a nightlife.”

Xu Yun:

"????"

No personal attacks, boss!

But even though Xu Yun felt a little nauseous in his heart, after hearing what Lao Guo said, he figured out the cause and effect.

really.

Unlike other political missions, the fact that so many cows came to the base cannot be suppressed.

As soon as the employees spread the word, the news naturally spread.

Originally, the base employees had some expectations for the Spring Festival because of the winter wheat available in the base. Now, stimulated by the news of beef and sheep dumplings, the entire base has become completely agitated.

Unlimited beef and sheep dumplings

Even in the capital city outside the base, it is something that cannot be believed.

At this time, probably only a few state-owned agricultural machinery factories with particularly good business and over a thousand employees would kill a few cows during the Chinese New Year to give everyone a good year.

Then Xu Yun glanced at Wang Aimin, whose eyes were shining, thought for a moment, and nodded slightly:

"That's right, we are eating dumplings during the Chinese New Year this year. They are so exciting!"

"Of course, the prerequisite for eating this dumpling is that everyone does not affect the research tasks at hand."

"In addition, I can also promise you that not to mention this year, every year from now on, we can eat dumplings until you vomit!"

Note:

I have surgery tomorrow, and there will be a three-day high-risk observation period after the operation. I will automatically update the saved manuscript. If there are any typos, it will probably take a few days to correct them.

Also, please give me some monthly tickets. I am still a bit nervous about having a thoracotomy.
