Chinese people have always been in a state of knowing what it is, but not knowing why it is. Pen? Interesting? Pavilion wWw. ｂiquge。 info to the good.,It's more pragmatic.,Don't understand if you don't understand.,It's good to be able to use it.。 It's not going to be too ambitious.

To put it mildly, it's almost sir. Like Hu Shi's biography written by Mr. Similar, everything is about the same, and it doesn't need to be too precise.

This kind of thing is experienced in production, that is, by experience. For example, in iron smelting, the experience is how high the flame rises, or what color it is, or how much fuel it puts in, how much iron can be trained, and how good iron can be trained. For example, the production of ceramics is also done in the world. I didn't think to control the temperature.

I don't know how to know the temperature, after all, there is no standard tool. can only rely on the master to lead the door and teach the experience hand in hand. This kind of thing, it is even difficult to write a book, appeal to words, experience such a thing, how to say? Sometimes it's just a little bit subtle. Even, craftsmen are basically illiterate, and if they want to write books, they have to rely on literati.

The Chinese literati also preferred writing methods such as hazy and Spring and Autumn brushwork, and they themselves did not know much about the craft. I got a rough idea and wrote it.

Take Tiangong Kaiwu as an example, there is a mention of steel-making method, some people retort that that method is impossible to make steel, take wooden sticks to stir, how can wooden sticks withstand thousands of degrees of high temperatures, although it is very similar to the kind of converter steelmaking in later generations, but the Chinese are stirring molten steel, but the question is, how to withstand that high temperature with wooden sticks?

When he saw this paragraph, he wanted to ask Song Yingxing what kind of stick he needed to withstand being put into a thousand degrees of molten steel without burning it, unless it was a modern Goryeo stick with a skin thicker than the earth's crust, otherwise it would be difficult to use a wooden stick.

Well, it's far away, now with a thermometer, a lot of things can be quantified, no longer rely on experience, you can write a book, you can be accurate, steelmaking, no longer put a fixed amount of coal, as long as the temperature is up, you don't need to add it to it. To make ceramics, as long as you look at the temperature, you will know whether it can be made or not, and you don't need to rely on experience. It is also more convenient and easy to write in writing, and it is easier to pass it on in the future.

However, of course, Li Chen will not let anyone be stupid enough to come up with a complete book of Datang science and technology, and write a detailed book on the development of Datang technology, so that people can know that Datang has to apply science and technology as long as they buy a book. From ancient times to decades after the founding of the People's Republic of China, the Chinese had no sense of secrecy.

In the civil war, anti-espionage was very good, and if you really keep high-tech secret, you don't know, this bad habit has existed since ancient times. Shen Kuo and Song Yingxing, if they were born in modern times, would be the culprits who leaked the country's high technology.

Continuing to talk about canned food, with a thermometer, the canning factory has experimented, there is no need to cook the canned food for a long time, more than 72 degrees, as long as 30 seconds, with a clock, the calculation time is much more accurate. If it's about sixty-two degrees, it will take half an hour.

The Datang version of the Dbas sterilization method came out. In the future, you only need to boil a pot of hot water, maintain the temperature, soak the can, and achieve the same preservation effect in a short time. However, the premise is that the cans have to go over the heat first.

After the heat, clean the can first before doing so. If the clay pot is directly filled, the sterilization time will be longer.

Li Chen knew the news, it was Su Xiaoxiao who told him. Because of the invention of this, the canning factory saved a lot of fuel and increased its profits a lot, Su Xiaoxiao, in the spirit of Li Chen's consistent reward for research, gave a bonus, and told Li Chen about it.

After Li Chen learned about it, he also gave a more special reward, in addition to the heavy reward, he also named this sterilization method after him, called Zou sterilization method.

This discovery is comparable to that Bass sterilization method. Without the Bath sterilization method, French wines would probably not be as famous as they are today. In fact, not only in France, but also in Europe, red wine is very common, and the price is even lower than mineral water.

Really, drunkards will really be happy when they go to Europe. Their red wine is cheaper than if you were to buy the same volume of mineral water. You can really drink wine as water. Not to mention the Bath sterilization method, which brings significance to the preservation of other foods. Because of its significance, you can read about this invention in history books.

For Datang, milk can be popularized. Animal husbandry can be promoted in the northern grasslands, cattle can also be raised, and the sales of dairy products will increase a lot. Although he felt that drinking milk was not suitable for Orientals, it could also be used to slowly. Besides, this is equivalent to another means of controlling the northern grasslands.

After that, the tinplate cans were replaced, and the disinfection process was a little less, and the clay pots were not as easy to conduct heat as metal. When the steam engine enters the application, the high-pressure boiler can raise the temperature to a higher level and sterilize faster.

In addition, shortening the sterilization time is also of great significance to the promotion of canned food. Because of the boiler, it can be steamed at high temperatures, which saves fuel and retains both nutrients and taste. One of the drawbacks of clay pots is that they can easily lose their original flavor after being steamed for a long time.

'Master, I'm going to give it a try. Li Chen opened two cans, and several children began to try them with great interest, Li Chen took out several can openers and let them try them. Speaking of this can opener, it is also an important invention to promote canning.

Originally, canned food was vigorously promoted because it was easy to preserve and transport on the battlefield. But the folk are not common, because it is not easy to open. On the battlefield, the soldiers used bayonets directly to open cans. It wasn't until the invention of the can opener that cans became popular. However, this thing had to be invented, and it was decades after the appearance of cans.

Don't waste it, you can't finish it. Chao's preemptively snatched the can opener in the hands of all the children, and if she couldn't finish eating, it would be very wasteful, there was no way, even if she was a concubine, she was still diligent and thrifty, this habit was developed by Li Chen in these years, taking care of housework.

If you don't save some money, you won't be treated by the emperor and see their family, and you won't be able to live a life. Although life can't go on, and it is much better than ordinary people, but the expenses of the palace are also large, and she has to be careful with her calculations.

After Li Chen ascended the throne, he could have lived a more comfortable life, but Li Chen found something to do for a few concubines, and the Chao family was responsible for managing the accounts. And because Li Chen himself is not extravagant, Chao's habit continues.

"It doesn't matter, it won't spoil all of a sudden, if it's cold today, you can't finish eating it later, you can give it to the palace women and guards." By the way, ask them for their opinions as a reference for future promotion. Li Chen smiled and asked the Chao family to test it for the children, anyway, there are many people in the palace, and it is cold in the first lunar month, so you can't eat it all at once, so you will give it to the servants to eat, and it will not be wasted.

It's not easy to promote. Su Xiaoxiao picked up an empty can and flicked it lightly with his hand, "Metal, it's not easier than a clay pot." 'Metals are expensive, although Li Chen has developed several large-scale iron mines after he ascended the throne, but in these years, it is difficult to get cheap.

It's a bit expensive, but it's not insurmountable. Li Chen thought for a while and said, "I just said that mechanization means, which can also be understood as industrialization, which means that it will be mass-produced, and the cost will be gradually reduced." ’

To put it simply, this metal canned food is indeed more expensive. Materials are expensive, and the cost of building a factory is also high. But there is no way to build a small kiln and get some clay like a clay pot, and you can make it at will.

However, Li Chen still wants to promote tinplate cans, even if it can't be promoted, as a munitions, there is still a big market. In addition, Li Chen also managed to reduce costs.

To reduce costs, it is necessary to mine in large quantities, facilitate transportation, and improve production efficiency. These points are currently in place, and they are gradually being available, which is why Li Chen is only launching tinplate cans now.

First of all, a large number of mining, Li Chen did not plan to gradually relax the use of gunpowder, but would increase the use of slaves in the mining area. Gunpowder still had to be regulated, at least until nitration appeared, black powder could not be opened. Then only slaves can be used.

However, Li Chen did not intend to make the people of the Tang Dynasty suffer, he was ready to use Nanyang, and even African black slaves, that is, Kunlun slaves. Africa is not far from the Arab world, it is easy to get some slaves, and there is also the Nanyang region, he is ready to import a large number of slaves, although the Tang Dynasty has been doing it before, but it should be said that the Tang Dynasty merchants are still more conscientious?

Although the maritime trade was developed, there were also such slave traders. But most of it is still done by those heavenly merchants. It's a pity that this kind of low-cost business is done by Tianfang. Indeed, the primitive accumulation of capital is bloody, but this kind of blood, as long as it is not the blood of the people of the Tang Dynasty, I care about him.

In addition to being known as Kunlun Nude Black Slave, Li Chen also introduced Indian Ah San. However, there are very few Indian Ahsan, and they are not used as hard laborers, they are dark, thin and short, and they can't dig any mines when they buy them. is mainly from Tianzhu, it seems that he is really good at mathematics, and Li Chen is mainly looking for talents in this area.

Minerals can be easily transported, that is, railways. Steam engines and locomotives were produced, which would have increased the efficiency a lot. With railways, the cost of transportation will be greatly reduced. As for the final improvement of tinplate cans, the production efficiency is mechanized tinplate canning machine. That is, the emergence of a large number of various machine tools in Datang has made this possible.

In addition, even for instant noodle production, Li Chen also asked the research institute to manufacture a instant noodle making machine similar to an assembly line.

Instant noodles are noodles that have been steamed at high temperature and then removed from the oil. Many of these parts can be mechanically improved, although it is not possible to automate them all. However, the manpower required is also much reduced. The power source of these two kinds of machinery is the steam engine, and with the steam engine, there is a stable power source that is not affected by the terrain and climate.

Of course, if you say that instant noodles are made with a steam engine, doesn't that make the noodles covered in soot? Instant noodles are electric motors, propelled by electromagnetic effects, and electric current engines.

The electric motor, which appeared at the same time as the steam engine, was really weird. Historically, it was decades after the appearance of the Watt steam engine that it appeared. However, again, this thing is a matter of perception. In fact, the principle of generator and electric motor is fundamentally the same.

The fact that electric motors were applied so late is mainly due to the backwardness of electricity research. Franklin, because of the lightning strike when flying a kite, invented the lightning rod, which will be forever recorded in history. However, it was not until after this experiment that the electromagnetic effect was discovered.

Within a few years of the electromagnetic effect, there were electric motors. It's just that the battery is too hard to consume and is put on the shelf. After a few decades, the process technology was relatively passed, and there was direct current, and direct current and DC motors. It took another few decades before there was a TRASSE AC motor.

In fact, if you study carefully and find these things, it is a difference in concepts. When the idea is clear, the thing comes out, and the difference is in efficiency and cost.

And Datang has crossed many thresholds as early as Li Chen's simple golden finger, electromagnetic effects, transformers, and electric/generators have already appeared. It's going to be delayed until now, it's too late.

It will drag on for so long, and it is only now that Li Chen has begun to promote electric motors. On the one hand, it is necessary to wait for the practical application of the steam engine before it can be used to generate electricity from thermal power. On the one hand, it is to gradually improve the process, otherwise the previous generator is really big enough.

Because it depends on copper wires, it is necessary to wind copper wires to achieve electromagnetic effects. Before, the copper mine was not developed, Datang copper was too expensive, and the wire drawing technology was immature, the copper wire pulled out was too thick, and the generator was so large that it was difficult to use, so it was extended to the present.

Well, tinplate canning and instant noodle factories are so involved, and they are steam engines and electric motors. It costs a lot of money to build a factory. It's hard to promote these.

Li Chen is mainly experimenting, allowing capital and technology to be concentrated. In this way, we can gradually move towards industrialization. He didn't know if the sudden release of the steam loom and the establishment of the steam loom factory would make the capital see that it was profitable and lack other opportunities to make a lot of money, leading to a swarm of people to build a textile factory.

The canning and instant noodle factory is an experiment. Royal Capital leads first, waits for the track, establishes a model for others, and slowly guides innovation, capital and technology. After all, before Datang, it was still in small-scale manual production.

There is a model that can make Datang's industrialization develop in the direction of improving technology and improving production efficiency, instead of exploiting workers.

Can it be done? Li Chen didn't know either. Even if he crosses the crowd, no one can say for sure about such a thing as social change. After all, time has changed, and Western countries can only refer to their development models, and Li Chen has tried his best to go in the direction he envisioned by referring to their development methods.

If only he could have predicted it, would this model have come to fruition. Before he crossed over, he would not have been a real estate agent, he would have been a think tank of the national think tank a long time ago, or he would have been relied on as a national teacher. In other words, he has the same level of characters as Zhuge Liang and Liu Bowen and other demons.

After a happy New Year, Li Chen finally wanted to meet those foreign envoys, but he had to know the information first. He didn't just want to be angry, so he deliberately hung them out. He had a purpose.
