The specific operation process is: after the development loan of 10 billion US dollars is debited, there will be hundreds of millions left after excluding the purchase of weapons and equipment, of which 3500 million US dollars will be used to introduce the daily chemical industry in India, and Procter & Gamble will use this Entered India and set up a joint venture Procter & Gamble India branch, and the joint venture shares in India came from the daily chemical industry fund of 3500 million US dollars.
Menon did not understand military operations, but he knew a little bit about military industry by analogy.He is most proficient in politics, and he has great power in the political and legal circles. Menon can really help broker this matter.
In exchange, Michael Roy will try his best to match up all the factories related to the important parts of F-104, and send people to join Eisenhower's visit next month to discuss with Hindustan Aeronautics Co., Ltd. about investing in the establishment of parts production plants and assembly plants. .
It's that simple.
……
Fangshan.
Tang Hua, a ministerial-level programmer, looked through the code left by Peng Hengwu on the hard drive.
Lao Peng is really a conscientious programmer in this era. Before turning on the hard drive, Tang Hua was a little worried that Lao Peng would leave him a mountain of shit, but that was not the case.The code is written very neatly, with sections clearly divided, and English comments are added in important places.
Of course, adding comments to the code is something that has been repeatedly emphasized and must be done in the B language tutorial written by Shanghai Computer.
The program left by Peng Hengwu, the first and largest one, is the "Qiong Qi" program.
This alien tiger with a pair of wings in the "Shan Hai Jing" is about to be assembled as China's first atomic bomb. The Institute of Atomic Energy Sciences has established a set of virtual programs that can simulate the first 2 milliseconds of the explosion of "Qing Qi" in electronic space. process.
2 milliseconds is actually not enough, and the parameters of the existing virtual program simulation are relatively rough.If the simulation standard is changed to improve the numerical accuracy; the time is extended to go back more than a dozen milliseconds, and start the simulation from the explosion of the explosive module; and extend it to a dozen milliseconds backward, then it is a real computer simulation of a nuclear explosion. .
However, this needs to increase the memory of Tianhe-100 by 10 times, and increase the computing speed by at least [-] times, and obtain enough real nuclear explosion parameters to ensure the correctness of program settings.
The "Qongqi" program in the hard disk is now used as a nuclear trigger for the light nuclear reaction group. The hydrogen bomb configurations designed by several of them all use "Qongqi" as a nuclear trigger.
The "Qiong Qi" program does not need to be adjusted by Tang Hua.There is also an entire folder in the hard disk, which is the design documents, simulation programs, simulation records and parameter calculation formulas of "Hundun". The design of Hundun has been completed, so this folder is no longer needed.
Then there are four programs used by the light nuclear reaction group to verify the configuration of the hydrogen bomb, namely neutron transport calculation, radiation hydrodynamic calculation, temperature and compression ratio calculation, and plasma calculation.
……
"I really didn't expect that your hydrogen bomb research has reached this point." Tang Hua said.
"The light nuclear reaction group was separated in May, and in June we successively summarized the issues that we had been thinking about before," Deng Jiaxian said, "The collection of papers on American atomic physics that you collected in the past few years is very important. Some useful information."
Tang Hua: "It's a pity that the number of papers on fusion physics in the United States was the most in 50 and 51. After that, it gradually decreased, and it was not discussed later. This thing is also a top secret for the United States."
"The cross-section of deuterium-deuterium and deuterium-tritium reactions was figured out in June. It was calculated by Sa Benhao, and the entry point he found was very good, so he came to the conclusion with the T6 computer assigned to him." Deng Jiaxian pointed out Refers to Sa Benhao, "The data released by the United States has been deliberately changed, leaving holes."
Sabenhow: "This is a routine calculation. After the deputy team leader got the data, he used the Brett-Wagner formula to prove that the cross-section of all light nuclear reactions does not exceed 5 bars. This pushed our work forward. One stop."
Yu Min not only used the Brett-Wagner formula to prove the upper limit of the cross section of the light nuclear reaction, but also continued to calculate the possibility of lithium deuteride 6 undergoing a violent deuterium-tritium fusion reaction on the spot after absorbing neutrons.
Then it got stuck. When most people saw the data calculated by Yu Min, their first reaction was: This is simply impossible.
However, the previous thermonuclear tests in the United States have proved that the United States initially used liquid tritium to make hydrogen bombs, and then gradually transitioned to tritium + lithium deuteride, and now it may be mainly lithium deuteride.
This path is doable.Even when your instincts feel like it’s impossible to keep going, keep going.
In July, August, and September, Deng Jiaxian pushed the battle line to the outside of the fortress. In the middle of the fortress was the target of the light nuclear reaction team: the hydrogen bomb.
……
The atomic bomb is not the treasure of the nuclear arsenal of a big country, but the hydrogen bomb is.The hydrogen bomb is also known as the deepest secret of all countries on the earth.
Holding a 155mm grenade exploded, the human body would turn into meat and scatter on the ground in a radius of more than 100 meters.
Holding a 2.5-ton atomic bomb explodes, the human body will vaporize, and the plasma gaseous matter will fly out at more than ten times the speed of sound, and spread to the entire stratosphere with the mushroom cloud.
Now someone tells you that if you put a lump of lithium deuterium 6 next to the atomic bomb, when the atomic bomb with the equivalent of 2.5 tons of TNT explodes, this lump of lithium deuteride 6 will not only not diffuse and fly away, but will also make it fly away for a certain period of time. It is squeezed with great force and maintained for a period of time until lithium 6 eats neutrons and turns into helium and tritium, until the temperature inside exceeds the fusion threshold, enough for tritium and deuterium to undergo fusion reactions?
I give you the pen, and you design a structure to realize the above functions. Anyway, Tang Hua doesn't do this.
Why is hydrogen bomb design so difficult? Some people have concluded that there may be two places where it is easy to get stuck:
The first is that it is necessary to conduct multiple nuclear tests in the atmosphere, including the test of the enhanced atomic bomb, and sample and analyze the products after the explosion of the enhanced atomic bomb from the atmosphere as the original reference data for the design of the hydrogen bomb.Therefore, after the prohibition of atmospheric nuclear testing, no new country has developed a hydrogen bomb.
The second possibility is that the design of the hydrogen bomb is too uncommon, like a super-difficult college entrance examination question that only the smartest minds on earth can solve.
……
"Minister Tang, you are now among the top ten smartest people on earth," Zhou Guangzhao said, "help me correct it, where is the design error of my configuration?"
Tang Hua: ...
It's all good deeds done by "Komsomolskaya Pravda". The key is that the article was translated and published in full by domestic newspapers.Next time I go to the Soviet Union, I have to settle accounts with President Komotsky.
For the Zhou Guangzhao-01 configuration posted on the wall, Tang Hua embedded the formulas, parameters, and processes in the program, and performed four calculations respectively. The results were very poor, and the utilization rate of fusion materials was higher than that of puff pastry. A little bit.
Tang Hua refused to make corrections.Deng Jia first looked at the configuration of Zhou Guangzhao-01, and thought that one of the places could be changed, but he tried to calculate it on the medium-sized computer next to it, and the effect was basically the same.
A total of 5 sheets of paper were pasted on the wall, and 5 hydrogen bomb configurations were designed. It took two days to program and perform rough calculations one by one. The results turned out to be similar, and the utilization rate of fusion materials was very low.
……
A truck stopped at the entrance of the Institute of Atomic Energy and put down four large wooden boxes. After the guards opened the wooden boxes and checked them inside and out, they put them on a small cart and pushed them into the courtyard.
This is the seafood that Tang Hua bought and shipped from Dalian.
"Your nerves were too tight at work a while ago," Tang Hua said. "At this time, you need to relax, relax, and change your mind. Maybe after a good rest, everyone will find new ideas. Have a meal, and then take a week off, and Lao Peng will be discharged from the hospital after a week, and the whole group will gather and start again."
After eating this meal, it's time for Tang Hua to go back...
"Fluid mechanics, high-temperature plasma, nuclear physics, neutron physics, inertial physics, more than a dozen kinds of high-energy rays, and data on pyrotechnics..." Zhou Guangzhao said, "This job combines all the knowledge I have learned before. It works, and it’s not enough.”
"And these sciences have to be used to a very deep level." Tang Hua cut the lobster open, put down the knife and prepared to eat the meat. "But the key is thinking. Sometimes you may have to jump out of the inherent thinking frame and look for something similar to inspiration."
Yu Min: "The harder it is, the more energetic I am."
Huang Zuqia: "What do you think the real face of the hydrogen bomb looks like?"
"This..." Tang Hua suddenly wanted to see if the Morand configuration could withstand scrutiny.
"This ball is 'Qongqi', and then this hollow column is lithium deuteride 6, and the middle of the hollow column is a solid column of uranium-238, and the outside of lithium deuteride 6 is filled with foam plastic. Hey, Lao Deng, your configuration is the same. The bubble was considered. That's it."
……
"At the end of November 59, the work of our light nuclear reaction team went from unconstrained theoretical research to the tough battle of engineering configuration. Everyone was very tired, and Peng Hengwu was overworked and hospitalized, but everyone had high fighting spirit."
"The first battle of the tough battle was annihilated. After supercomputer calculations, the efficiency of the five configurations we proposed was very low. After working hard for half a year, the structure of the hydrogen bomb is still a mystery to everyone."
"Minister Tang asked us all to take a week off to fight again with a different mindset. During the dinner party the night before the holiday, Minister Tang suddenly drew a hydrogen bomb configuration crookedly on the blackboard with chalk in the other hand while holding a wine glass. Everyone was shocked. Terrified, Zhou Guangzhao refined the crooked diagram, and listed a system of equations based on the information in the diagram, which is the 'Tang-Zhou configuration' in the development of the hydrogen bomb."
"We used the supercomputer to calculate the 'Tangzhou configuration' that night, and its utilization rate of fusion materials is not high. Compared with the first five configurations, it is only slightly improved, and it is still not practical. However, this configuration and The five configurations we thought of before were completely different, which made us realize that there are still many, many ways to try the hydrogen bomb configuration under the premise of satisfying the hard conditions such as compression and temperature rise."
"Encouraged by this, we all canceled our vacation, and everyone got up our spirits, stuck to our posts, and continued to fight for two weeks..." ——Memoirs of He Zaoma: "20 Days of the Birth of the Hydrogen Bomb", 1990.7.30
