Chapter 579: Electricity is also divided into genres

King Qin's request to South Korea can only be shelved. Can't solve it. Many things need professional personnel to provide reference. For example, the investment report of the banking industry in this industry, etc. These all need someone to investigate. Moreover, the more the Qin State's economy develops, the more obvious this trend of socialized division of labor, and the stronger the professional skills. The huge gap brought about by that kind of technology makes the general manager of this society feel at a loss.

Now this feeling has been tasted by Meng Yi and King Qin. I have no choice but to entrust a third party to appraise the investment report. After this report is verified, Qin can negotiate. This is why Shangwen feels more and more powerless. It is also an important reason why the establishment of a think tank is similar to a think tank. The technology is getting stronger and stronger. At this time, one person can no longer accommodate so many things. For example, Qin State gave birth to many occupations that did not exist before, such as electrician, engineer, editor, reporter, typesetting, investor and so on. Qin Guo did not make detailed statistics, but these industries do exist and have played a huge role.

Shang Wen can't manage these, he is in the research room of Qin Guo University like a duck in water. Research and experiments here are doing various experiments everywhere. On average, more than 200 technical patents are born here every day. These technical patents will soon be sold out by small and medium-sized companies or investment bankers like supermarket items. Everyone knows the huge revolutionary results of the new technology.

For example, a large number of innovations in electrical appliances have been born here. Electric machine bed equipment. This set of equipment is driven by various electric motors. The electricity comes from coal or various fuels. As long as it can make your boiler generate electricity and burn the **** cow dung. After the electric machine bed equipment is changed. It can be used in various ways.

For example, a milk bottle filling machine. That machine can fill 50,000 bottles of milk in one day's working hours. This also directly led to the atmosphere of drinking milk in Xianyang. Those milk delivery workers are from Zhao country or South Korea, they can put them in the box as long as they see the user's box. Then recycle the bottle.

Not only can it be filled with milk, but it can also be filled with others. There is also a mixed drink of milk and tea, as well as various juices. Qin's demand for drinks is huge. Even water is the same. The springs from the Qinling Mountains have also begun to be sold as a kind of beverage. If you put it in the past, people think this is a little bit unreasonable. That's what Zhao Guoren and Korean people think. Qin was so crazy that he paid for a bottle of spring water. It's hard to imagine.

Not only filling machines, but also Qin's textile machines and sewing machines have begun to be driven by electricity on a large scale. This has also led to the emergence of various power plants. In the laboratory, there are more and more experiments on electricity.

People find that electricity has a wide range of uses. At this time, people finally realized the meaning of resistance, which appeared according to different resistances. Electricity can emit light and generate heat. Although light only exists for a moment, it is really wonderful if you keep this moment for a long time. This is the idea of ​​the electric light.

In addition to electric lights, there are various electromagnetic induction products. The microphone and PA equipment made Shang Wen very happy, so that he would not have to yell out loud when he publicized it in the future.

There are also people in the laboratory researching early earphones. The emergence of this kind of equipment will greatly solve many voice transmission problems. But it takes a lot of work on the film. However, the paper industry provides a variety of papers. After using a large number of chemicals and new papermaking machine tools, Qin's paper industry has been able to produce a variety of different types of paper, including special paper.

Specialty paper is specially used in special industries, mainly for photography, voice transmission and so on. A kind of carbon fiber bamboo paper made from bamboo seedlings carbonized and fused with other bamboo materials from Bashu provides a good material for it. This kind of paper has a certain degree of elasticity after being stretched. Remember that it is only a certain degree of elasticity, that is to say, but when the amplitude of the voice is too large, that is, the amplitude of the vibration exceeds this elasticity, the film will break . This is also the reason for the ongoing research on headphones. People need to find a more suitable material to make up for this shortcoming.

Qin Guo made many electrical inventions. It is mainly the wide application of electric motors. For example, things in gantry cranes are driven by electric motors to push hydraulic pistons to complete large-scale lifting equipment or winches. Because the thickness of steel plates in the north can no longer be completed by manpower, the demand for a large-scale lifting equipment has stimulated the emergence of such equipment.

Shangwen hadn't visited enough, but he saw two researchers arguing fiercely.

"I think the application of direct current is wide enough." A young researcher argued fiercely.

"Oh. Come on, direct current, look at the poor voltage. How big can be driven. Only alternating current will work." A middle-aged man said defensively. He is an electrician who is a monk, and experience is his main achievement. But a lot of failures. This is also the reason why people acted against him because he failed.

"What are they arguing about?" Shang Wen asked an onlooker.

"Direct current faction, and alternating current faction several times." Onlookers looked at the two and shook their heads.

Shangwen listened for a while and finally understood. It turns out that this is a confrontation between alternating current and direct current. In history, there has also been such a confrontation in electricity. As for whether DC power is widely used or AC power is widely used, it has been impossible to reconcile for a period of time in history. After several meetings, the problem could not be solved.

Direct current is the electricity we usually use, and its voltage value is small. But it is enough to threaten the safety of human life. Can drive large-scale motor equipment, AC power is mainly high-voltage power. He can reduce the loss of electricity through the high-voltage line with extremely low loss. Obviously the two researches are in different directions. However, Shangwen was a little surprised that that kind of middle-aged man turned out to be the discoverer of the arc. Arc, to put it bluntly, is the electric spark phenomenon that we usually see, and it is a kind of arc.

And he suggested to use higher voltage to make a large-scale arc, and control the arc with some professional equipment, because the arc can generate a high temperature. This high temperature can control its temperature under the control of the equipment. This is one of his conjectures.

And he kept propagating this conjecture in order to help, but the distinction between alternating current and direct current made his research progress slow. Shang Wen is helpless, and electricity is also assigned.
