At this moment. By the jeep.
Seeing the man who suddenly appeared behind him, Lao Guo's face suddenly lit up with joy.
This person has a Chinese character face, piercing eyes, a high and shiny forehead, thick and fluffy black hair, and slightly protruding apple muscles. At first glance, he is a person who loves to laugh.
And it's interesting.
At first glance, this man seemed to be in his forties, but upon closer inspection, he seemed to be in his early thirties, and his smile looked more like that of a young man in his twenties. Saw this person appear.
Lao Guo quickly handed the box to Cai Shaohui, laughed and stepped forward to hug him hard: "Guangda!"
After separation.
Lao Guo put his hands on both sides of the opponent's shoulders again, exerted a little force, and smiled and cursed:
"Well, Lu Guangda, when did you come back from Malan? I didn't hear any news about you when I left in the morning." The middle-aged man named Lu Guangda grinned and showed a bright and innocent smile. :
"It's not long since noon, so I'm two or three hours ahead of you. I just squinted in the dormitory for a while." He said.
Lu Guangda's eyes fell on the suitcase in Cai Shaohui's hand, his expression moved slightly, and he guessed: "Lao Guo, could this be..."
"Sh-"
Lao Guo quickly raised his index finger to his lips and made a silent gesture towards him.
Then he took Lu Guangda's hand and said to Li Jue and Peng Mengxiong beside him at the same time: "Guangda, Lao Li, Lao Peng, there are many people here, let's go to the conference room to chat." Li Jue and Lu Guangda looked at each other. , all nodded.
Then Lao Guo looked at Cai Shaohui again, patted him on the shoulder, and told him: "Shaohui, you go back to the team to check the situation first, I will go there later."
Cai Shaohui understood that they had important matters to discuss, so he naturally had no objection to it - although he was Lao Guo's partner, his position was just that of an ordinary researcher.
Although the employees who can enter Factory 221 have gone through strict political review, all of them are extremely reliable.
But whether it is Lu Guangda or Lao Guo, what they are involved in is the top secret among top secrets, so it will never hurt to be careful. After the division of labor is completed.
Cai Shaohui said goodbye to several people.
Li Jue took Ruo Laoguo, Peng Mengxiong and Lu Guangda to find a remote conference room and asked the guards to be on guard outside. After entering the house.
Lao Guo put the box in his hand directly on the table and entered the six-digit password. Click-
The combination lock popped open.
Then Lao Guo lifted up the box, revealing many foreign language periodicals inside, and said to Lu Guangda: "I counted it, there are a total of 73 independently bound books, large and small."
"Thirty-nine of them are printed documents, and the rest are handwritten contents. Guangda, come and take a look." Hearing this.
Lu Guangda quickly came to the password box and couldn't wait to read through it. "partleshoer...."
"Generationofneutrndhigh-density...unterpropagatinserpulses..." "Bidirectional one-dimensional alternating implicit format..."
As he flipped through more and more journals, the expression on Lu Guangda's face became more and more excited.
Previously, the theoretical research team of the base compiled a batch of very critical data lists, the number of which was about 150. According to Lu Guangda and the others, it would be good to get 10% of the money in the end.
After all, those comrades in the foreign affairs department do not know which issue of the journal contains these contents, and can only quietly find out through their own relationships.
The result was unexpected.
This time, Lao Guo actually brought back more than 70 pieces of information, most of which were the content they had compiled before? ! This is really not easy...
Suddenly.
Lu Guangda's hand movements paused, then he let out a sigh and his eyes fell on a handwritten English manuscript. This manuscript only has three pieces of paper. The paper is very thin and can be easily used with a small clip.
Clamped into one portion. Lu Guangda carefully held the manuscript in his hands and looked at the title above with shock:
"Steady-state subcritical state model..." After a while.
Lu Guangda took a deep breath, turned his head suddenly, stared at Lao Guo, and asked, "Lao Guo, where did this manuscript come from?"
"Steady-state subcritical state model... This is core-level data from the Los Alamos National Laboratory across the sea. It is absolutely, absolutely, absolutely impossible to spread nuclear theory secrets!"
When saying this.
Lu Guangda used three "absolutes" in a row, which shows his inner surprise. Students who have done atomic bomb research should know this.
In the development of nuclear weapons.
Theoretical design is the most important part. In a sense.
It is more important than isolating uranium-235.
Each country's theoretical research on nuclear weapons is led by its own physics community. For example, the theoretical design of the Manhattan Project across the sea was directed by Hans Bethe.
The Wooly Bear is hosted by Kurchatov. John Bull hosted by Chadwick.
The person in charge of the theoretical design of the rabbits is... Lu Guangda.
At the beginning of taking office, he determined the main directions of the Rabbits' atomic bomb theoretical research: fluid mechanics, physical properties under high temperature and high pressure, and neutron physics. And in neutron physics.
Neutron transport is another absolutely core item.
Because the atomic bomb is described in theoretical terms, it can be summarized in the following sentence:
The so-called atomic bomb is to instantly transform a nuclear device in a subcritical state into a highly supercritical state. This is the relevant category of neutron transport.
To complete this step, one of the key technologies is... the calculation method of the unsteady neutron transport equation.
Of course.
The real core point of this equation lies in the high-supercritical calculation of the motion state, which is an advanced version of the stationary subcritical state model that Lu Guangda had at this time.
But this does not mean that the stationary subcritical state model is not important. Actually.
This model is considered core-level data for any country—because through this model, it is entirely possible to derive highly supercritical equations of motion states.
But now such a top-secret data model appeared in front of Lu Guangda... How could this not surprise him?
Although there is not enough time for calculation.
But with Lu Guangda's superb physical literacy, after a few quick glances, he was at least 70% sure that this was a real model manuscript and not a bait deliberately released from across the sea.
And opposite him.
Looking at the handwritten manuscript in Lu Guangda's hand, Lao Guo's face instantly became extremely heavy. -
-......
I saw Lao Guo's chest rise and fall a few times, exhaled a heavy breath, and explained: "Guangda, this is the information that Changyou exchanged."
"Changyou?" Lu Guangda was slightly startled.
Subconsciously, a thin man appeared in his mind, who was not tall and had missing teeth, spoke with a strong Southern Fujian accent, and wore a British hat:
"What did he use in exchange for it?" Lao Guo glanced at him: "Use your life." Use your life.
Two simple words.
But Lu Guangda and Li Jue's pupils suddenly shrank.
Then Lao Guo sighed again, turned his attention to the manuscript in Lu Guangda's hand, and said:
"My friend did not return to China with us that year, but stayed at Los Alamos National Laboratory and served as Norris Bradbury's assistant."
"He has been providing all kinds of information for our research."
"After receiving secret letters from China last year, he began to accelerate the collection of various documents."
"I even took advantage of my position to obtain the relevant model of the stationary subcritical state. I don't know how I obtained it. I'm afraid how many times did I get it?
Ten or hundreds of years later, this will remain an eternal mystery. "
"Four months ago, he handed over the last batch of information to our comrades. Not long after, he "accidentally" fell down and died." Lu Guangda heard this.
Subconsciously, I tightened the corners of the manuscript.
But before Lao Guo finished speaking, he only heard him say again:
"Two months ago, this box was sent to the Malay Peninsula, and my friend Brother Zu Ling was responsible for handing it over." "As a result, the news leaked out during the handover process. Fortunately, Brother Zu Ling brought another similar fake box in advance. "He handed the real box to our comrades and left the scene with the fake box, trying to fool himself."
"Unexpectedly, the Malay British police officers did not even give them a chance to defend themselves during the pursuit. Later, I heard that Brother Zu Ling had 21 bullet holes in his body..."
Bang - Lao Guo just finished speaking.
Lu Guangda punched the table hard, his chest heaving violently.
Li Jue and Peng Mengxiong also had expressions as dark as water. As one of the earliest batches of international students in China.
Many of Lao Guo and the others...or it can be said that most of them left the country through channels such as "Genggqian". But what they long for is not the blue sky and white sun, but the bright red five-pointed heart.
After the founding of New China.
Quite a few Geng money have made it clear that they are willing to return to the country and make contributions. 1950.
Mr. Zhu Guangya took the lead in co-writing "A Letter to Students Studying in the United States" with 51 students studying in the United States, which set off a wave of overseas students returning to China.
Xinhuaxia has also cooperated in organizing many batches of international students. Over the past two decades, more than a thousand international students have returned to China. But again.
Considering that domestic non-applied physics research is lagging behind.
Therefore, some international students who were originally willing to return home immediately chose to stay across the sea after communicating with the country's senior officials. over time.
Some of these international students have returned to China one after another more than ten or decades later, working hard to contribute to the country. Some did not fulfill the contract due to changes in their thinking, but stayed across the sea, or even chose to immigrate.
Others, like Mr. Zu Ling and Changyou, transported valuable information to the country through their own channels and sacrificed their lives for China's scientific research.
throughout the nuclear research enterprise.
More than 30 Chinese scientific researchers who are blood-stained in foreign lands have been disclosed to the public, and the number that has not been declassified is probably not much less. At the same time, it is even more regrettable.
Since a considerable number of these scientific researchers were overseas students with Geng Geng scholarships, they did not acquire Chinese nationality when they died. Therefore, the rabbits are unable to even appeal.
At that time, the only person qualified to attack them was the island across the strait, but... a moment later.
Lu Guangda suddenly raised his head, looked at Lao Guo, and asked, "Lao Guo, do you have a list of those comrades who died?" Lao Guo nodded:
"Yes, it's just a simplified version that I compiled myself. It only has names and dates of sacrifice, no photos and no resume." Lu Guangda stretched out his hand towards him:
"show me."
Without much hesitation, Lao Guo reached into his inner pocket and took out a folded piece of paper from the pocket containing the pills.
Then he flattened the paper and handed it to Lu Guangda.
Lu Guangda took the paper with both hands and looked at it solemnly.
Then he sat back down, took out a pen and paper from his body, and started copying carefully. Ma Zuling...
He Changyou...Min Xuesi...a few minutes later.
Lu Guangda finished copying the list and handed the original copy back to Lao Guo.
Then he carefully folded the copied list in half and put it in the inner pocket of his chest. Lu Guangda was calm throughout the whole process, but beneath this calm, there was a flame burning. ...
After a while.
Perhaps it was because the atmosphere in the conference room felt a bit dull. Lao Guo coughed lightly and changed the topic:
"By the way, Guangda, what did you gain from going to the Malan base this time?
How about it? "Lu Guangda tapped his index finger on the table a few times and shook his head:
"It's not ideal. The problem caused by the chain has been successfully solved, but the nuclide density during the chain transfer process has never been up to standard."
"So we must further efficiently concentrate radioactive materials, or consider slowing down neutrons to increase the probability of collision between neutrons and atomic nuclei and prolong the number of chain reactions."
"It's too hard to slow down neutrons."
After Lu Guangda finished speaking, Peng Mengxiong, who had not spoken much, quickly shook his head:
"This involves the problem of existing materials. Unless the materials are quickly updated and iterated, it is impossible to achieve this step." "But further concentration of radioactive materials...it depends on whether the comrades over at Jincheng can do it." .”
Say it.
Peng Mengxiong looked at Li Jue who was aside. Upon seeing this, Li Jue immediately raised his hand and expressed his stance:
"Jincheng, right? No problem. Leave the contact to me."
"Comrade Guangda, you'd better summarize the specific data or parameters that need to be met into a written report for me later. This will be more efficient." Lu Guangda nodded:
"good."
Then he paused and asked Li Jue:
"Commander Li, I wonder how the construction of the detonation test site at the base is going?" Hearing the words "detonation test site".
Lao Guo also showed a trace of concern on his face.
Mentioned before.
Among the current 221 factories, there are a total of 18 factory areas and 4 living areas. The functions of these 18 factories are also different.
For example, Factory 17 is a warehouse for food and daily necessities, Factory 11 is a dangerous goods station, etc...
Among them, there are mainly five branches responsible for tasks related to nuclear weapons research, namely 12367.
The first branch is responsible for warhead body processing, uranium component production, precision machining and radio system control.
The Second Branch is mainly responsible for the processing of explosives, simultaneous focusing experiments, processing of pyrotechnic components and the assembly of nuclear weapons. The third factory is a mechanical processing plant, responsible for sand foundry, forging, heat treatment and oxygen production.
Branch No. 7 is the experimental site for radiochemistry and neutron physics. As for the No. 6 branch, it is...
Detonation test site.
This is a place responsible for detonation tests. It is large in scale and is still under construction even at this time. The independent building modules under each branch factory have a special name, called 'work number'.
Among them, the detonation test site plan has five job numbers, that is, five independent building modules. "The explosion test site..."
Hearing this, Li Jue glanced at Lu Guangda and frowned slightly: "To be honest, I also encountered some difficulties."
"Take the No. 2 observation room currently under construction at the detonation test site as an example. This observation room has very high requirements for the walls."
"So in addition to the material itself, when the wall is poured, there should be no rainfall or strong winds - otherwise sand and gravel will be mixed into the wall."
"But currently our technology cannot accurately predict the climate. We can only ask the comrades of the sideline team to collect climate samples for analysis every day."
"Comrades have put in a lot of sweat, but in the end we still have difficulty controlling the weather conditions, which is very troublesome." Hearing Li Jue's words.
Lu Guangda couldn't help but said "tsk" in embarrassment. He clenched his hands into fists and inserted them into his waist, with a gloomy look on his baby face. Weather forecast...
This is really a problem.
The detonation test site is an important location used for explosion experiments in the mine. For the sake of personnel safety and experimental data collection, the buildings such as the observation room must strictly meet the standards.
But the problem is that the construction of the observation room involves the mysterious field of nature, and today's meteorological observation methods are obviously somewhat ineffective. Currently, the factory-affiliated meteorological center of Factory 221 can only provide more accurate data for the day at 11 a.m. every day.
And to be honest at this time...
Ordinary people look at the sky in the morning
You can tell what the weather is like today from the sky.
in this case.
In order to ensure that there will be no quality problems at the detonation test site.
The construction team can only wait for the meteorological center to provide accurate weather trends for the day. ． ． ． That is to say, construction can only be carried out after 11 noon. This way.
The construction site wastes a full ten hours from early morning to morning every day. If only someone could accurately predict the weather...
But....is this possible? ........Note:
There was no update yesterday because I was on leave for surgery. Don’t worry too much. I haven’t received any review notification yet.
Due to timeliness reasons, the chapters cannot be synchronized with the facts, so you can join the book club group, and I will tell you anything in the group.
