Some people may think that Factory One deserves the title.
Because it is responsible for the development and testing of nuclear device systems, nuclear warheads, etc., it is the lifeblood of the base.
Some people may think that the second factory is the soul.
The development, production testing and overall assembly of high-energy explosives it is responsible for provide the most basic power for the atomic bomb and are the absolute mainstay.
Some people may think it is the fourth branch factory, the sixth branch factory or the main factory, etc...
In short, the public opinion is right, and the mother-in-law opinion is right. It is difficult for anyone to come up with a consistent result.
But if we change the question.
Choose the most common branch factory.
So most people will probably vote for...
Branch 16.
Branch 16 not only ranks at the bottom, but also has the smallest number of employees.
At the same time, its functions are relatively low-key:
It is mainly responsible for sewage treatment.
After all, sewage treatment these days is not as important as everyone knows it in later generations.
In addition, the industry itself is not as high-tech as it will be in the future, so most people only have five words for it:
Digging into the sewer.
The location of the 16th branch factory is also very consistent with its "personality". It is located in a relatively flat open space in the Jinyintan grassland.
The factory area also has a strange smell mixed with disinfectant due to long-term sewage treatment, which does not look eye-catching at all.
And just in the southwest corner of this nondescript factory complex stands a group of similarly nondescript buildings.
The building complex consists of three small buildings connected together. The middle one has three floors, and the two adjacent buildings are two floors.
There is a circle of earthen walls surrounding the outside, and a rusty iron gate at the entrance.
There were no soldiers standing guard next to the iron gate. There was only a middle-aged man in his forties sitting in the guard box responsible for registration.
However, despite the ordinary appearance of this building complex, it looks like an old shabby little tube building.
Actually.
It has a name that sounds quite bluffing in this era:
Factory 221 belongs to the Meteorological Strategic Command Center.
Its main function is as the name suggests, which is to inspect, monitor and predict the weather of Jinyintan Grassland.
At this moment.
The building of the Meteorological Command Center was bustling with noise, and there were constant exchanges:
"Xiao Wang, please derive these feature numbers!"
"Which comrade has done the total differential of time? Please send me the file!"
"Old Liu, don't take off your shoes on such a hot day..."
"Master, I have made the flux divergence form of the continuity equation."
"Sister Lingling, can you lend me your hand-cranked calculator (that's what it's called)? It only takes five minutes..."
Amidst the noisy exchanges.
Ye Duzheng, then director of the Meteorological Center, was sitting on his desk, spinning a tachyon in his left hand and staring at a piece of data in front of him with a deep expression.
After a while.
Suddenly a male voice with a Jiangsu and Zhejiang accent sounded in his ears:
"Brother Duzheng, you are turning fast again."
Ye Duzheng paused slightly while turning Kuaizi's hand, and subconsciously looked up at him.
After seeing the other person's face, he suddenly became happy:
"Brother Shiyan!"
The brother Shiyan described by Ye Duzheng is a man with sallow skin, thick eyebrows and slightly high cheekbones.
He looked no more than forty years old, and he had a severe bald spot on his forehead.
This person's name is Tao Shiyan, who works as a consultant at the meteorological center of the base and has a very good relationship with Ye Duzheng.
More than ten years ago.
Ye Duzheng and Tao Shiyan also collaborated to study the atmospheric circulation in East Asia, pointing out that the plum rains in the Yangtze River Basin are closely related to the sudden changes in the atmospheric circulation in the northern hemisphere in East Asia.
This is also the first time that the meteorological field of the Republic has achieved results with international influence after the founding of the People's Republic of China.
However, Tao Shiyan did not stay at the base as often as Ye Duzheng. He also had some scientific research to do in the capital and could not just focus on one side.
So in a sense, he is somewhat similar to Lu Guangda.
I usually run in both directions and return to the base every once in a while.
The last time Tao Shiyan returned to the base was four months ago. The joy of meeting old friends made Ye Duzheng temporarily put aside the nervousness in his heart.
He quickly stood up, pulled a chair from the side to Tao Shiyan, and greeted:
"Come on, brother Shiyan, sit down quickly, sit down quickly."
Then he raised his head again and said to his assistant and half-disciple Zeng Qingcun:
"Xiao Zeng, please excuse me and go get two glasses of water."
Zeng Qingcun, who was sitting next to Ye Duzheng, quickly stood up:
"Okay, Teacher Ye."
Tao Shiyan looked at this scene with a smile, and gently raised his chin in the direction where Zeng Qingcun left:
"Du Zheng, is this the apprentice you brought? I heard he is a top student who came back from Mao Xiong?"
Ye Duzheng nodded and said:
"Well, the mentor is Mr. Kibel, who is now my assistant researcher."
"He is very diligent and down-to-earth, and his future achievements should not be too low, but it is too difficult to communicate in Cantonese Mandarin..."
Tao Shiyan suddenly laughed.
Then he glanced at Kuaizi on Ye Duzheng's table and raised his eyebrows:
"Du Zheng, which number is it?"
Ye Duzheng glanced at him and made a six-character sign.
Tao Shiyan couldn't help but smile and shook his head.
When Ye Duzheng was studying at the University of Chicago, he picked up a habit of turning his pen when thinking about problems.
This habit was later brought back to China by Ye Duzheng.
As a result, during a pen-turning process, he accidentally knocked the pen away, and a good pen was damaged.
Although the pens at that time were not controlled materials, they were extremely valuable.
So from then on.
Ye Duzheng changed the pen into a tachyon to spin.
In his words, this thing is so sturdy that it won't hurt if it breaks.
Even though ballpoint pens are now available in China, which are cheap and not easy to break, he still did not choose to change them.
In the later documentary filmed by Ye Duzheng in 2007, Mr. Ye proudly showed off a pair of copper tachyons that were about to be transferred out of the pulp...
This chapter is not over yet, please click on the next page to continue reading! After a while.
Ye Duzheng's assistant Zeng Qingcun came to the two of them with two cups of hot water.
After Zeng Qingcun returned and left.
Tao Shiyan picked up the glass of water and took a sip.
Then he straightened his face and asked Ye Duzheng:
"Du Zheng, I heard a news on the way here, that is, the wind cup wind speed sensors sent from the capital are all functioning normally?"
"Yes, I was just about to tell you about this."
Hearing this, Ye Duzheng put his palms on his left and right knees respectively, leaned forward slightly, and explained:
"Some time ago, an international student who graduated from Cambridge University came to the base. His name is Han Li. I don't have the confidentiality level to know the details, but he seems to like steak - I heard them often mention medium rare."
"Then a few days ago, Gong Yao from the sideline team led a team to maintain the watchtower. To tell you the truth, our expectation at the beginning was that we could just find an exhaust gas tower that would not shake very much."
"Unexpectedly, Han Li happened to be there and tinkered with some kind of damper..."
Ye Duzheng introduced the ins and outs of the whole thing, and at the end he clasped his hands together excitedly:
"...Hey, that thing is really cool. Once installed on the watchtower, it will stop shaking immediately."
"Various equipment is now installed on the 19 watchtowers, especially the humidity sensor sent from the capital. It has been operating normally for two days!"
Hear that last sentence.
Tao Shiyan couldn't help but raise his eyebrows.
To know.
Humidity sensors in this era do not use organic polymer films as media as in later generations. The value can be measured through changes in the humidity-sensitive capacitance caused by polymers, and can be easily used on the ground.
The humidity sensor Ye Duzheng mentioned is actually a thermocouple instrument made using the Seebeck effect.
Its working conditions need to be at an altitude of more than 30 meters, and at the same time, the absolute stability of the load-bearing platform must be ensured.
Among the several pieces of equipment sent from the capital this time, the humidity sensor is the one that Tao Shiyan thinks is least likely to be put into normal operation.
after all.....
Its requirements are too high.
Even the equipment in Xiangshan in the capital has a specially customized carrying environment.
In the end, the Cambridge international student who was said to like medium-rare steaks solved this problem by relying on a few water tanks?
Tao Shiyan is not an expert in mechanics or engineering, but he estimates that most of those experts are already questioning life at this moment...
Then very quickly.
Tao Shiyan suddenly realized something else:
"Genuinely, since these instruments can operate normally, doesn't it mean that we can try to calculate the weather model?"
"yes!"
Ye Duzheng was so excited that an English sentence came out of his mouth. At the same time, he rummaged around on the table and pulled out a document about two centimeters thick:
"Here, look at this, I spent two days calculating the model."
Tao Shiyan reached out to take it and read it carefully.
After a while.
Tao Shiyan couldn't help but raise her head and her eyes stayed on Ye Duzheng's dark circles for a while:
"Du Zheng, have you even considered the negative local spatial gradient?"
Hearing this, Ye Duzheng changed his posture, put his hands on his chest, and showed a trace of the Dragon King's smile:
"That's right."
As we all know.
Although atmospheric dynamics is a very complex thing, the physical knowledge it involves is not actually "cold".
The physical concepts included in atmospheric dynamics mainly include momentum equations, continuity equations, thermodynamic equations, etc.
That is Newton's second law, conservation of mass and conservation of energy.
Of course.
Just like some chefs can make potatoes look like flowers, some people can only use molds to shred potatoes.
Although these physical phenomena seem simple, they are very complicated in the actual calculation process of atmospheric dynamics.
Atmospheric dynamics is such an esoteric subject that the calculation result for a predicted date exceeding seven days is worse than rolling dice, let alone now.
Today's meteorological centers can only rely on human power to deduce various results, which is extremely primitive.
Of course.
It is precisely because there is no assistance from equipment such as supercomputers.
Atmospheric engineers during this period were still in a situation of "I know this problem is difficult, but I don't know how difficult it is".
Just like the online novels of later generations.
Many readers know that it is difficult to update 30,000 times a day, but their understanding is nothing more than staying in a dark room and coding for more than ten hours.
In fact, only if you really come into contact with this industry will you know that 30,000 updates a day is really a beautiful expectation...
That's what meteorology is like right now.
At that time, Richardson even proposed the naive idea that 64,000 people in a factory could calculate numerical weather forecasts for the world...
If the actual meteorological calculation involves 100 decimal places, the meteorological community explored 10 decimal places during this period.
So at present, the meteorological community’s guesses about the meteorological values that can be derived are around 12 or 13 digits at most.
That is to say, it is a category that can be cracked with a little effort.
When weather satellites appear and develop to a certain extent,
This value will be extended to 20 digits.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Then ECMWF proposed four-dimensional variation.
Meteorologists will discover an extremely sad reality:
This thing tmd is like a SLR, no matter how many times you count it, you can’t see the end...
But on the other hand.
It is precisely because of the current limitations of perspective that humans have the courage to challenge the calculation of nature.
Ye Duzheng is such a ‘brave man’.
Then he took out a piece of paper and pen from the side, and scribbled down a few numbers:
"Brother Shiyan, look, this is the covariate tensor I calculated."
"My idea is to first convert the Cartesian coordinate system into surface coordinates, and split the continuity equation into horizontal and vertical directions for calculation..."
"As for trace substances, I decomposed the instantaneous concentration into the mean term and the turbulence term based on Reynolds decomposition, that is, φi=φˉi φi′′..."
A few minutes later.
Snap.
Ye Duzheng put down his pen and said to Tao Shi:
"Brother Shiyan, what do you think of this derivation?"
"There will be no heavy rain within three days. The probability of rainfall is 30% in the morning of the fourth day and 60% in the afternoon. It is impossible to judge at night."
"The probability of a sandstorm is 0 within two days, and the probability is 73% between 10 and 16 o'clock on the third day."
Tao Shiyan's eyes stayed on the thick calculation paper for a while, then he touched his chin and said:
"Logically, it makes sense, but to be honest, I always feel that changes in fluids in three-dimensional space are not that simple. Especially in the boundary layer, I still feel that there is a lack of data..."
Talk about this.
Tao Shiyan stopped talking.
He knew very well that Ye Du was a smart man.
With my friend’s IQ and EQ, I should be able to understand my thoughts without saying too much.
as expected.
Hearing Tao Shiyan's words.
Ye Duzheng was silent for a moment and sighed slightly.
I saw him put his hands behind his back, stood up from his position, and said:
"Brother Shiyan, Comrade Youlai also has the same view - although he is not a meteorological expert, the calculations are still interoperable."
"Comrade Youlai?"
Tao Shiyan was stunned for a moment, and then quickly responded:
"Du Zheng, have you handed this prediction result to the Standing Committee?"
Ye Duzheng nodded, his expression becoming more solemn:
"Well, it was submitted yesterday and unanimously approved. Construction will start today."
"..."
Tao Shiyan opened his mouth, wanting to say something.
But in the end he didn't speak.
Too.
The equipment has been running in a stable state for many days without any external interference in the environment.
Almost all the data that should be collected has been collected.
At the same time with the help of dampers.
The diversity and completeness of these data far exceed the base's earlier expectations.
The meteorological center then invests in human calculations, and the results obtained, whether correct or not, basically represent a concept:
It is the highest precision currently available to humans.
If the prediction is successful.
This means that there is a high probability that the construction team will be able to successfully... even complete the construction of the detonation test site ahead of schedule.
But if it fails...
It means that the investment in instruments and manpower will become worthless in an instant, and the research and development of nuclear weapons will also be seriously affected.
In the face of these two results.
Whether or not it will be accompanied by construction today has become secondary.
The base can sit back and wait for three days, or it can trust the prediction that groundbreaking will begin today.
If you succeed, you can save three days, but if you fail, you will lose a lot of supplies.
But no matter which choice.
In the face of the verification problem of prediction accuracy, it can only be regarded as an additional step.
Think of this.
Tao Shiyan couldn't help but pick up the water glass and took a sip of water.
However, while drinking water, he suddenly heard some subtle noises in his ears.
These sounds were crisp and rapid, and their pitch seemed to be increasing in pitch.
The orientation is...
Tao Shiyan was stunned for two seconds and then realized something.
I saw him suddenly turning his head and looking towards...
The window sill two meters away from him and Ye Duzheng.
Just at this time.
From where Tao Shiyan was looking.
A huge drop of water landed on the glass of the window, exploded instantly like a flower bag blooming, and then slowly rolled down the window edge below.
Then comes the second one....
The third one...
Heaven——
It's raining......
........
Note:
Let’s play a little game. There are several academicians who appeared in this chapter. What are their specific names? If you guessed it correctly, I will add a 4,000-word chapter tomorrow. The time will end at 12 o’clock tonight. (You can clearly tell me that there are pitfalls, otherwise it is impossible.
I’m confident that I’ll add more updates, so don’t say I’m cheating when I announce my answer, but it won’t be so outrageous that I can’t guess it at all)
