Into Unscientific Chapter 699

Chapter 699 The restless base

Light and shadow are intertwined, and the years are rushing.

 In the blink of an eye, time flies by in the scroll of time.

 Suddenly.

The fallen leaves are flying, and the chilling autumn has unknowingly bid farewell to the stage of the four seasons.

Instead, the white winter snow covered the earth, and the snowflakes fluttered, as if the whole world was 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, despite the wind, snow and stars.

“Consultant Xu, thank you for your hard work today.”

  221 base.

  Second branch factory.

Outside a certain ordinary-looking small building.

A middle-aged man of about forty was holding Xu Yun's hand with a smile, and said enthusiastically to him and Lao Guo beside him:

“Consultant Xu, you have solved another problem for us.”

“Thanks to you this time, if you hadn't taken action, our project team would have been stuck again for a while.”

Hearing this, Xu Yun quickly shook his head and kept his posture very low:

“Professor Li, you are serious, I just did some trivial work.”

“I am younger than everyone else, and my thinking is more out-of-the-box, so I just got lucky and came up with some ideas that everyone didn't notice. I was afraid that you would dislike me for not being steady enough.”

“It is the comrades of the project team who really verify the feasibility of the idea and implement it into applied technology. I dare not take credit.”

 The middle-aged man smiled when he heard this but said nothing.

If Xu Yun is only able to solve the problems of various project teams once or twice occasionally, then maybe it is indeed related to his active thinking.

 But as far as he knew.

Xu Yun has solved more than dozens of problems for various project teams so far, with a success rate close to 80%. This cannot be explained by "thinking outside the box".

 Nowadays, because Xu Yun's image in a wheelchair is somewhat similar to that of 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.

 Across from 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 but shook his head in his heart.

 He is really vain.

 That's right, he has given reasonable and appropriate answers to many of the problems encountered by the project team so far, but these answers basically have nothing to do with Xu Yun's own professional knowledge—after all, he is not engaged in nuclear engineering.

His answers either rely on partial intersections in related fields, or they directly apply the future achievements of some big guys in the project team.

 In short, it's ctrl+c and ctrl+v.

 For example, what happened to the middle-aged 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 materials expert.

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

 At present, they have a total of 9 project team members in the 221 base (excluding production workers), who are mainly responsible for the research and development of zirconium alloy cladding pipes.

Zirconium alloy cladding tubes are an important structure of nuclear reactors. They do not play much role in atomic bombs, but they are quite special in the detonation process of hydrogen bombs.

 The reason why it is said to be special is mainly because zirconium alloy cladding pipes have a relatively moderate structure, and the definition is somewhat vague.

 That is to say, it must be available, but the technology does not need to be very advanced.

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

Hyun Zhenhua head power supplies are good, but if you really want to compress the configuration, anything from Xianma, Jinhetian, etc. can be used.

But on the other hand.

 You can keep reducing the brand and price of the power supply, but no matter how you reduce the budget, it will definitely not work without a power supply.

So the task of Li Hengde and his team is to at least come up with a beggar's version of zirconium alloy cladding pipes.

Li Hengde started working on the second day after arriving at the base, but soon they discovered a problem during the research and development process:

Zirconium alloy has comprehensive excellent properties such as small thermal neutron absorption cross-section, good mechanical properties, high temperature resistance, and good corrosion resistance, but it can easily cause brittle fracture due to the orientation of the hydroxide.

 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 causes the alloy atoms to leave their lattice positions and generate point defects without changing the target atoms.

At the same time, zirconium alloy has a high affinity with hydrogen and is easy to form hydride. Especially at high temperatures, hydrogen is more likely to diffuse into zirconium alloy, thus affecting the mechanical properties of zirconium alloy.

 After reaching a certain situation, zirconium alloy will undergo brittle fracture.

For those who can't understand this sentence, you can imagine that when you get hard enough, it suddenly breaks in half.

This problem troubled Li Hengde and his colleagues for a full week. After determining that it could not be solved within the group, they sent an application for assistance to the advisory group.

This is why Xu Yun is here today.

 It's a coincidence.

Although Xu Yun has nothing to do with reactors professionally, he does know something about zirconium alloy cladding pipes.

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

However, zirconium alloy cladding tubes are still used in the field of nuclear reactors, and Xu Yun has been exposed to its structural information to some extent.

 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, it is calculated that 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.

 This idea was finally solved successfully after calculation by Li Hengde's team.

 That's even more coincidental.

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's like you traveled back ten years and published a book "The Lord of Best Friends" based on your memory, and then one day you found Cuttlefish praising the book in the comment area. I rewarded you

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

“Professor Li, please don't be polite. We all contribute to the country.”

“If the project team encounters any problems in the future, they are welcome to come to the staff hospital to see me. As long as I have not gone 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 still the same 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.

These problems were later 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 in 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.

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

But before he opened his mouth, 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. His appearance was average, but his hairline was very high—probably enough to compete with future generations of Penguin T3 programmers.

Xu Yun remembered that the other person 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.

Seeing this, Xu Yun 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:

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

Xu Yun suddenly had a surprise in his eyes.

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

Schoolmates who are Chinese in this life should all know this.

As the first of the four traditional Chinese festivals, the Spring Festival is of far greater significance 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.

The first day of November in the Zhou Dynasty and the first day of October in the Qin Dynasty.

 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 - this 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 animals, 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 generally speaking.

No matter how much he criticized the New Year, in the era when Xu Yun traveled back in time, the Spring Festival was still a festival with a special status 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 eat steamed buns and drink two sips of oily soup. The north wind is blowing outside and the snow is flying, which will only make everyone more sentimental.

 Xu Yun has experienced this.

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 her hometown because she lost her job, so Xu Yun's uncle did not come 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's emotions while eating that meal will never be forgotten.

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

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

But very quickly.

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

“Advisor Xu, I heard that our base will make beef and mutton dumplings during the Spring Festival this year. Can everyone make the kind of dumplings they want?”

Hearing this, Xu Yun subconsciously raised his eyebrows, 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 for the Chinese New Year is only known to the base management, and it has not been made public for the time being.

In the end, I didn't expect that 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:

"How new is it? There are so many people in the base. Unless it is 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 transportation, there are other employees going to and from get off work along the way. When you see so many cows, why don't you ask a few questions?”

"Also, for example, the leaders of the base all have wives, right? If a young couple mentions this kind of non-confidential matter after a night out, maybe someone's wife will tell it at work the next day - oh, I forgot, you No wife, no 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.

  Different from 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 hope for the Spring Festival because the base had winter wheat. Now, stimulated by the news of increased holdings of beef and sheep dumplings, the entire base has become completely agitated.

Unlimited beef and sheep dumplings

Even in the capital Demon City outside the base, this is something that is unbelievable.

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 make everyone happy.

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

“That's right, we're going to eat dumplings during the Chinese New Year this year, so make them!”

“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, we can eat dumplings every year from now on until you vomit!”

Note:

 The surgery is 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. The thoracotomy surgery is still a bit nervous.
