Chapter 517 An unprecedented six-star mission!
"."
I don’t know if it’s the effect of the halo or my own psychological effects.
In short, the moment this light curtain appeared.
The pain in Xu Yun's body suddenly disappeared temporarily, which gave him more time to think about the reminder in front of him.
As everyone knows.
The history of China can be divided into three periods.
One is the ancient feudal period before 1840 AD.
The second is the era of humiliation and self-redemption from 1840 to 1949 AD.
The third is New China after 1949.
Looking at the development process of New China, it can be divided into two stages.
In the first stage, China could only be regarded as a populous country that had just been established and was waiting for development.
Although some impossible wars have been won through willpower, objectively speaking, the international voice is still very passive.
To put it harshly.
He is just a "beggar" holding a stick, with ragged clothes and a sallow complexion. Although he can use the stick in his hand to explode and hit people, he can only stand hunched over most of the time.
But in the second stage.
China has truly entered the realm of being a "powerful country" and can stand tall and confidently raise its head to talk to any country.
The node that determines these two stages is
The emergence of China's first atomic bomb.
Later generations will know that the first atomic bomb in China was exploded on October 16, 1964, and when mentioning the atomic bomb, many people will think of one word:
Gobi Desert.
But actually.
This matter is far from simple.
The origin of China's research on atomic bombs can be traced back to the mid-1950s.
At that time, the other side of the sea was defeated on the South Korean Peninsula, and they began to deliberately seek trouble to issue nuclear threats to the rabbits, claiming that they would drop atomic bombs on the mainland:
At that time, a certain neon emperor whose name began with the word "Mai" proposed to use atomic bombs for nuclear strikes. Four of them would be used to destroy the rabbits' troops on the peninsula, four of them would be used to bomb the rabbits' air force airport, and the rest would be reserved for local use.
Under the cloud of nuclear bombs.
1953.
The famous physicist Mr. Qian Sanqiang made suggestions to the country to develop its own atomic energy industry.
Then two years later.
The top management of Rabbit decided to carry out nuclear weapons research and signed a relevant assistance agreement with Mao Xiong.
In July of the same year.
GWY established the Construction Technology Bureau of the National Construction Commission responsible for the construction of nuclear research bases, with Mr. Qian Sanqiang as deputy director.
In the same year, the Third Ministry of Machinery Industry, also known as the Third Machinery Department, was established to take charge of nuclear industry construction and nuclear weapons development.
From then on.
The Rabbit and the Bear began to assist the nuclear industry. The Bear began to provide relevant drawings and personnel, and helped a lot in the basic industry.
Then in the fall of 1957.
The Second Machinery Department established nine bureaus, with Li Jue as the director and Lao Guo as the deputy bureau.
By the way.
The Ninth Bureau of the Second Ministry of Machinery was the predecessor of the later China Institute of Engineering Physics.
If it develops according to the trend at that time.
The rabbits should be like John Bull.
After paying a not-too-exorbitant price, we finally succeeded in possessing nuclear weapons, a big killer, and it didn't make much of a splash.
Descendants of dozens or hundreds of years will probably see this sentence in history books:
[With the assistance of Mao Xiong, our country successfully tested nuclear weapons in xxx and mastered the complete research and development methods of nuclear weapons].
But sadly.
For some well-known historical reasons, woolly bear experts began to evacuate the mainland.
They moved away a lot of equipment that had not yet been handed over, burned a lot of data and drawings, and left nothing for the rabbits.
The rabbits could only pull at the ashes and try their best to piece together the few unburned corners.
They were like a master who said he would teach Mengxin how to cook, but suddenly changed his face after Mengxin prepared the store, pots, and seasonings.
Not only did they not tell Mengxin the ingredients and processes needed for cooking, but Mengxin also poured out all the seasonings, broke pots and pans, and even burned the store to the ground overnight.
Mengxin rummaged through the ruins and found only the remaining salt.
But here’s what those furry bear experts might not have thought of.
The fire they set off did not burn away the hopes of the rabbits, but gave the ancient nation of China a fire of Nirvana.
Since then.
It was as if the rabbits were fooled. In just a few years, they independently developed their own nuclear weapons.
This seems to be a novel written by an ultra-nationalist who refused all help from foreigners and only relied on the "All-Chinese Class" to obtain the fruits of victory.
Of course.
One thing that needs explaining is.
Although the atomic bomb was detonated in Lop Nur, its development was actually not in the Gobi Desert.
Throughout the entire atomic bomb research process, the rabbits had three important bases.
One is the enriched uranium production plant in Jincheng.
This is China's first enriched uranium production plant, also known as the famous 504 plant, which is specially used to refine and enrich uranium ore excavated from the Nanchen 711 mine.
Don’t think that this technology is nothing special.
Students who have purified uranium ore themselves should know this.
Uranium is an important raw material for nuclear weapons, but what is actually needed is uranium-235,
But in a piece of uranium ore, 99.3% is uranium-238, and the content of uranium-235 is only 0.7%.
so what.
If you want to obtain uranium-235, you can only use chemical means to purify the uranium.
Electrons have the final say in chemical reactions, but neutrons don't care.
So chemically purified uranium is composed of 99.3% uranium 238 and 0.7% uranium 235.
Since the chemical properties of the two are exactly the same, if you want to separate them, you can only rely on the small difference in weight between the two.
In later generations, the most mature method in this regard was the centrifuge.
That is to say, the uranium is first turned into uranium hexafluoride gas, and then placed in a cylinder for rotation.
Gas molecules of different weights will be stratified. The heavier ones will be squeezed to the sides, while the lighter ones will stay in the middle. They will then be extracted separately with a catheter and placed in the next tube to continue rotating.
Do this a few times and the concentration will gradually increase.
This process requires a lot of power support, which is not a small amount even in later generations.
This is also the reason why everyone suspects that Neon has been secretly hiding nuclear materials - judging from Neon's power generation capacity, they probably have hidden nuclear materials, but it is not uranium-235 but plutonium-239.
This will still be the case in future generations, let alone now.
To save electricity.
The rabbits even came up with the ion exchange and gas diffusion method, which consumes far less power than Manhattan. The specific principle is... ahem, I can't say that.
So in conclusion.
Factory 504 is actually a very critical link in the entire nuclear weapons development process.
By the way.
Wait until the 1990s,
Due to the adjustment of the military-to-civilian policy, Factory 504 also started some sideline business to generate income, and produced the famous 504 ice cream, which should be the childhood of many Jincheng friends.
The cream used in the processing of 504 ice cream at that time was spun out of centrifuges in the nuclear industry, so it was very delicious
Except for the 504 factory.
The second important base is the Malan base.
The Malan base is located in Lop Nur. The so-called 'Gobi Desert' as everyone knows it and the place where the story in the movie "Survival of the World" takes place is at the Malan base.
The main function of this base is for nuclear testing.
Actually.
The original site chosen for the Rabbits nuclear test base was not Lop Nur.
According to the advice of Mao Xiong experts, the nuclear test site was originally going to be established near Dunhuang, and the nuclear explosion center was only 130 kilometers away from Dunhuang.
But later, considering the protection of cultural relics in the Mogao Grottoes, the superiors decided to change the test base to Lop Nur.
Lop Nur base is adjacent to Bosten Lake. It was named Malan base because the nuclear test living area is covered with beautiful Malan flowers.
The entire Malan base covers an area of 100,000 square kilometers, which is equivalent to the total area of Zhejiang Province - a nuclear explosion has a destructive radius, and this area can bear the impact of a nuclear explosion with an equivalent of 3 million tons.
In addition, talking about the Malan base, there is a very interesting story.
Many people born in the 80s or 90s must have played a rubber band jumping game when they were young. When playing the game, everyone would sing a nursery rhyme:
Small rubber ball, kicked with feet, Malanhua blooms twenty-one, two-eight-two-five-six, two-eight-two-five-seven, two-eight-two-nine-thirty-one.
This nursery rhyme is well-known, but its meaning is actually very confusing.
If I had to explain it, it should be easier to understand just the six words [small ball, kicking], and the rest is a bit strange.
Many people may have hummed it throughout their childhood or still don’t understand its meaning.
Actually.
This nursery rhyme is about the nuclear explosion at the Malan base.
China's earliest atomic bomb had a rounded spherical shape with many winding wires on it. Related pictures can be found online.
This round shape is the "little ball" in the nursery rhyme.
The "kick" refers to the process of detonating the tower and blowing it apart.
The former name of XJ Malan Base was the 21st Experimental Training Base of the General Armament Department, referred to as 21 Institute. This is the origin of Malan Blossom 21 - a film produced by Changchun Film Studio that tells the story of the development of my country's first atomic bomb. The drama is called "Malan Flower Blooms"
As for 28256 and 28257, they refer to Box 28, Box 256 and Box 28, Box 257. They are the only communication methods for the confidential base to communicate with the outside world.
Of course.
There is no way to know the authenticity of the statements about box 256 and box 257. After all, the specific mailbox at the Malan base has not yet been decrypted. We only know that information exchanges must be forwarded to Yanjing first and then back to Malan.
However, Malan Blossom Twenty-One is indeed a nursery rhyme compiled by the Propaganda and Education Bureau under the Ministry of Propaganda. This was mentioned in an interview in Mr. Zhang Pinghua's documentary.
It is precisely because of the coverage of the Propaganda Bureau that this nursery rhyme can spread to every corner of the country - although some places may have experienced magical changes, most places have remained unchanged.
Actually.
Many games played by children in the 1980s and 1990s were guided and promoted through the Education Bureau and its derivative systems.
So in that period when the Internet was not developed, many people could have the same childhood even though they were thousands of miles apart.
Okay, let’s get down to business.
Except for Malan Base and 504 Institute.
The third important base prepared by the rabbits for nuclear weapons is
Jinyintan nuclear weapons research and development base, namely Factory 221.
It was the Atomic City of Xihai Province in later generations.
Jinyintan Base is located in Haiyan County, Xihai Province, covering a total area of 1,100 square kilometers. my country's first nuclear weapons development, testing and production base was selected here.
From a research and development perspective.
Factory 221 is undoubtedly the soul area of the entire nuclear weapons development.
Don't look at the movie "Born Out of the Sky", Lu Guangda has been staying at the Malan base with Lao Li, General Feng Shi and others.
Actually.
Including him and other experts, the one where everyone stayed the longest was Factory 221.
Except for the 504 factory, the above three major bases have all become attractions for external exhibitions in later generations. It is recommended to visit them if you have the opportunity.
Quite literally.
If there is no actual object like the atomic bomb to prove it.
There were many deeds and technological breakthroughs during this period, which were completely beyond the scope of acceptance and understanding by ordinary people in later generations.
Xu Yun didn't expect it.
That mysterious halo actually allowed me to travel to this era?
This is an era that makes people’s hearts tremble just thinking about it!
Tell the truth.
Take a look at China for five thousand years.
This era is undoubtedly a period that is well-deserved in line with the concept of ‘national destiny’.
But on the other hand.
Although the success of the atomic bomb has greatly increased the rabbits' international status.
But from the perspective of future generations, there are actually many areas that can be optimized in this period - this refers to scientific research, not politics, and Xu Yun would not be stupid enough to touch certain untouchable lines.
Now Halo has given itself a chance.
Xu Yun made a decision without even thinking:
Whether it's for Yuxi or the country, he must do something this time!
What does it mean to be level with the sky?
It is just the fifth country to develop an atomic bomb. As Confucius said, five words will not work!
If you want to do it, you have to do it.
The man who steps on the sky!
Of course.
The slogan sounds nice, but it is not easy to implement.
After all, the entire nuclear weapons research and development process is highly confidential. It is basically impossible to enter the core of the project without passing detailed political review.
So at this moment.
There are two problems facing Xu Yun.
The first is to recover as soon as possible and end the sex scene.
The second is to find a suitable opportunity. Not to mention stepping into the core level of the base, at least to gain the trust of the organization to a certain extent.
Otherwise, your so-called impact on the project will be out of the question.
And just when Xu Yun was thinking.
Lin Yu beside the bed spoke again:
"By the way, this comrade, I don't know what your name is?"
name?
Xu Yun was slightly stunned, and subconsciously wanted to tell his real name.
But fortunately, he realized the risk before exiting, so he was silent for a moment and changed his name:
"My name is."
"Han Li." (End of Chapter)
