The weapon tycoon who traveled to Daqin

The principle of high -pressure cookers is very simple for Shang Wen. But for Qin Guo, who has just established an education and research system, this is still an unknown fan. And found that a process is required. For example, this problem is found by Captain Ma Zhendong, who is involved in the weather observation, found

It wasn't, but he couldn't explain this phenomenon. Of course, Shang Wen knew what was going on.

The high -pressure cooker is composed of the pot body, the pot lid, the easy melting slices, the firing hole, the safety valve and the sealing rubber ring, and other new forms of the airwalking channel. But now, the steel materials are very tight. Not to mention making the pot.

Thinking of this, Shang Wen's heart is explaining why it can't be popular.

The production of new materials takes a time process. The level of use is also different. These Shangwen cannot be managed for the time being, and then manufacture, steel, and become important materials for high pressure. Some key things Shang Wen uses steel to replace.

The lock -up mechanism. This structure can be used on the gun.

The pot body is made of stamping. It is not hand -made. Before the Qin Guo military factory appeared, a "iron helmet" was made of a whole iron plate, which was used to block bullets.

"Iron helmet." Obviously not cost -effective. So, it was abandoned. The production mold was used to produce iron pots. The price of coal is abnormal. The price of coal needs to be transported from the distant north.

Use the medium number of stamping.

The high -pressure cooker was made. Workers don't understand what this thing is used. Shang Wen didn't want to explain, so he personally did an experiment. Boil meat.

The same weight, the same water, the same fire. The time to use the pot is short. Do not guess.

The high -pressure cooker won naturally.

"What is this?" Qin Wang asked the Evening News in his hand. Zhao Gao gently lowered the Duan disk in his hand and answered.

"On the king, this is the chicken soup from the long princess. His Royal Highness Princess personally cooks." Zhao Gao said.

"Oh. Yuer will also cook soup. The widow tastes it." Then, King Qin put down the newspaper in his hand, and now King Qin put most of things to do Shangwen to do it. And he can only check it at any time. The newspaper is

The appearance makes politics began to appear to some extent transparency. Qin Wang reads the newspaper every day, which is actually equivalent to understanding all aspects of Qin State. Decentralization is that under certain monitoring, King Qin dares to do so.

"Well." King Qin picked up the jade spoon and took a sip.

"On the king, how?" Zhao Guo asked whispered.

King Qin swallowed more painful.

"The fire is almost almost." Qin Wang said. In fact, Yu Yu put the salt too much. After Meier put the material and get the salt out in advance. And the jade saw that the salt was too small, and then put a more more more than one more.

A spoon. And a big spoon. Others have to try, and Yu Yu believes that it has been given to Shang Wen to go to Shang Wen. Shang Wen did not move. It was sent to King Qin. Only Qin King who suffered.

My children can be filial and happy, and even if there is anything wrong, I will not say it naturally.

And the jade that eavesdropped outside the window said whispered. "No. I have boiled for more than two hours, and I should have reached the heat."

"The principle of high pressure cooker is very simple, because the boiling point of water is affected by the gas pressure, the higher the air pressure, the higher the boiling point. On the mountain, the plateau, the air pressure is less than 1 atmospheric pressure, and the water can be boiled at less than 100 ° C.

It is not cooked. When the air pressure is greater than 1 atmospheric pressure, the water will boil when it is higher than 100 ° C. The high -pressure cooker commonly used by people is designed with this principle.

The water vapor generated by evaporation cannot spread to the air, and can only be kept in the high -pressure cooker, so that the air pressure inside the high pressure cooker is higher than one atmospheric pressure, and the water is boiled when it is higher than 100 ° C.

In the environment, the rice is easy to cooked quickly. Of course, the pressure in the high -pressure cooker will not be unlimited, or it will become a bomb. "Shang Wen explained to everyone.

"This is called the atmospheric pressure that is so powerful!" The workers surprised.

"The atmospheric pressure exists naturally, not a person." Shang Wen explained patiently.

"Oh." Everyone nodded. Seeing everyone still understands it. Shang Wen believes that it seems that the Qin Kingdom's physics is urgently needed for progress. Otherwise, if you can't even know the atmospheric pressure, then the experiment in the back of the experiment will be

It cannot be done at all. Because this is this pressure and decompression, it has given a test method for chemistry, so that many of these industrial products must be used from oil and coal. Many of these industrial products must be used by weapons.

Then, then

There are many experiments that prove the atmospheric pressure. For example, the most famous is the Madebo Hemisphere experiment. There is also the Tori Drinking Experiment. This experiment measured the value of the atmospheric pressure. Shangwen decided to imitate Mayor Madebao and publicize this experiment.

Shang Wen draws a drawing to let the workers make it. At the same time, Shangwen asked about pumping devices. There are some answers. Because many places have begun to use pumping pumps. The train has been used.

Shang Wen decided to make it by himself.

At that time, the rubber ring was used in Madebao's experiment. And Shang Wen did not have this material. Shang Wen has experimented with various sealing materials. Most of the sealing materials of the Qin Kingdom use graphite, steel ring or other materials. Materials.

The expensive is undoubtedly the resin, there are a lot of rosin in the resin. At the same time, there are also animal gelatin boiled from animal bones, that is, capsules.

In order to do this experiment, Shangwen had to use the two mixtures of resin and gelatin. For the experimental failure, Shang Wen, especially the leather as a sealed material.

Two thirteen -inch copper balls are filled with water under special sealing. Then pull out the water to make it vacuum. Then let Mara just make it. But now it is in the early morning.

, Shang Wen can only open the pumping place. Return to normal values. Without the audience, it has lost its meaning.

However, Shang Wen decided. This experiment will be carried out tomorrow afternoon. Shang Wen notified the news to the major newspapers. The newspaper left special personnel on duty. They were responsible for the Morning Post because the newspaper must be distributed every day. The newspaper must be distributed.

Go to each household in the subscription.

When the newspaper received the news, it was already four o'clock in the morning. The printing of the newspaper has begun. In order to seize the favorable position of the news, they have to post another special issue. This news is announced.
