Siheyuan starts from a good life

Last night, the three of them chatted around the campfire for a long time. It wasn't until midnight that Jiang Yan and Yang Xiaomeng went to rest in the underground nest. Xu Damao, a good-for-nothing, was already asleep inside.

They stayed in the forest for three days before returning to Xiao Zhou's shack. During these three days, Jiang Yan found an opportunity to wander around the forest alone for a long time and got a lot of things, including silly roe deer and There were more than a dozen sika deer and five or six wild boars. Jiang Yan collected these prey into the space. This was the most supplies he had replenished since coming to the Northeast.

Jiang Yan took a bite of the grilled dried meat. To be honest, the dried meat that has not been marinated is unpalatable. It also tastes fishy. It tastes like chewing wax, which is different from the popular air-dried meat in later generations. They don't all have the same taste, so Jiang Yan only brought a little of these dried meats. However, there were many people drying bacon, sausages and hams in Xiao Zhou's shack. Jiang Yan and the others collected a lot, and the most collected were various mountain delicacies. , Jiang Yan also saw the opportunity to send some to his space, otherwise, the trunk of Jiang Yan's jeep would not be able to fit, and even this would be a large amount.

Back in the factory, Jiang Yan began to be busy again. In order to cover up his space, Jiang Yan also entrusted Xu Damao to mail a lot of the things he collected to Sijiu City.

Time flows like water. It has been almost three years since I arrived in Bingcheng. Before I knew it, time came to 1959. During these three years, Jiang Yan could be said to have spent all his time researching and copying various mechanical products, such as lathes, planers, etc. Jiang Yan drew drawings of machines such as milling machines, drilling machines, grinding machines, and boring machines one after another. The appearance of these drawings strongly supported the construction of the country. Jiang Yan's name appeared in the eyes of senior officials again and again.

Now Jiang Yan's level is almost the same as Director Yang of the steel rolling mill. Due to the projects Jiang Yan left for the steel rolling mill and his overt and covert help in the past three years, today's steel rolling mill is not the deputy department-level enterprise in the original novel, but A department-level enterprise, it is also a well-known star enterprise in the First Machinery Ministry and a large taxpayer.

"Da Mao, you have no hair at all," Guo Jianjun, who came over and saw Xu Damao coming out of Jiang Yan's laboratory with a disgraced face, laughed unfaithfully.

"You're still laughing at me, don't you have no hair anymore?" Xu Damao touched his shiny head and said back to the laughing Guo Jianjun.

Hearing Xu Damao's words, Guo Jianjun also touched his bare head and fell silent in depression.

The two of them still can't figure out what Jiang Yan is researching in the laboratory now. If he is not careful, it will catch fire. There are security personnel standing outside his laboratory all year round, ready to go inside to put out fires.

From the time Jiang Yan started the experiment, the hair of the people he was close to, including Jiang Yan himself, was burned, but nothing happened to the others.

Jiang Yan, who was in the laboratory, watched calmly as the security personnel put out the fire and ordered them to clean up. After Xu Damao and Guo Jianjun sent over the new experimental equipment and materials, they began to experiment.

One day, two days and three days, countless fires and countless failures, Jiang Yan was still studying his stuff seriously. Even if all the leaders came to persuade Jiang Yan, Jiang Yan still went his own way.

Looking at the three high-energy fuel formulas in his hand, Jiang Yan's eyes became a little moist. It's not easy! I don't know how many times I failed before I finally came up with these three formulas. With this high-energy fuel, I can make high-explosive bombs.

Although the computers in Jiang Yan's space can be connected to the Internet, Jiang Yan found that the network on his computer could only search for some relatively public things. Although the high-explosive bombs were introduced online, the formulas for the high-energy fuels poured into them were only Just a few words, but fortunately Jiang Yan was exposed to similar formulas in later generations, so he had no choice but to bite the bullet and get them out.

The reason why Jiang Yan chose the cloud explosive bomb was that it was known as a "sub-nuclear weapon" in later generations. The main charge of the cloud explosive bomb was cloud explosive, also known as fuel-air explosive. Cloud blast is a high-energy fuel, not an explosive. When the detonation reaction occurs, the explosive relies entirely on its own oxygen supply, while the cloud explosive bomb makes full use of the oxygen in the atmosphere in the explosion zone: under certain detonation conditions, the cloud explosive agent is thrown away, mixes with the air, and explodes violently. , some people call it cloud explosion.

The destructive effect of cloud detonation on targets is mainly due to the overpressure and temperature field effects generated by the detonation, as well as the scouring effect of high-temperature and high-pressure detonation products. Cloud explosives release much higher energy than explosives of the same mass, and the resulting explosion shock wave can destroy military targets in a large area. Detonation waves are reflected and superimposed between walls, and the overpressure value is much higher than that in open spaces, so the lethal effect of cloud blast bombs is greater in confined spaces. Therefore, individual cloud explosive bombs are particularly suitable for attacking living targets in houses, buildings and bunkers.

Early cloud explosives can be divided into secondary explosions during the explosion process. The first detonation is used to explode the fuel contained in the container and mix it with air to form an aerosol cloud. The second detonation is used to detonate the cloud and create a detonation effect.

The fuel is solid or liquid, which simplifies the structure of the fuel-air bomb, reduces costs, and improves reliability. Compared with TNT explosive, 1 kilogram of cloud explosive is equivalent to 3.2 kilograms of TNT explosive.

Its detonation time is dozens of times longer than that of ordinary bombs, and the invasion time of its high temperature and high pressure on the target is also dozens of times longer, so its destructive effect is much greater than that of ordinary bombs. Because cloud and mist detonation consumes surrounding oxygen, the explosion site is generally severely deprived of oxygen within four minutes, causing suffocation to humans and animals.

You know, after the relationship between SL and us broke down, there were millions of troops in the border areas. If it weren't for the victory in resisting M and aiding C, SL would probably have invaded, but they also clamored to threaten our country with nuclear weapons.

In fact, Jiang Yan thought very simply. As Dean Qian said, nuclear weapons have two different concepts: having no sword and having a sword without using it. Now the country is making great efforts to build that sharp sword. Before the sword is shaped, , Jiang Yan didn't mind bringing out a relatively sharp knife first, and at least maintained a low-level counterattack, allowing them to use a rat-proof weapon.
