"This kid is not simple, at a young age, how can he think so much?" Su Huandong was surprised, but also couldn't help but have a strong interest in the other family's education methods, how did a family in an ordinary town educate such a child? Although it is said that Fang Mingyuan said in the book on the left and the teacher on the right, Su Huandong values Fang Mingyuan's thinking method of problems more than that, and is not constrained by those frames at all, and often makes leaps and bounds, and it is precisely these ideas full of jumps that give him many hints. With these points and the abundant information in hand, Su Huandong is confident that he will write a report that will impress the Minister of Railways and senior national leaders.

Fang Mingyuan attaches so much importance to the transformation of this railway level crossing to an overpass, and even takes the American railway as an example to go around such a large circle, in the final analysis, he does not want to pay attention to this work from the beginning of his own railway speed, and form an example, so no matter which line is renovated in the future, or a new line, the builders have to take this work into account. Thus forming a good haode cycle. Su Huandong is naturally no stranger to the work style of these people in China. It is no surprise that cutting corners and dragging mud and water, if you say that you do not pay enough attention to this matter in the report, then this matter is likely to drag on for a long time before it is put on the agenda.

That's it, he can be regarded as having the benefit of this child, how embarrassed to refuse his little request.

"And, Grandpa Su, weishenme our trains can only be pulled by locomotives? If every car can provide power, then it will be easy to increase the speed. I know it's hard for a steam locomotive to do that, but what about an electric locomotive? It doesn't seem like a difficult task to install an electric motor in every car, right? Fang Mingyuan bit his fingers and asked innocently.

In his previous life, he had read some information about the Shinkansen, and as mentioned above, the Shinkansen locomotives were operated in a decentralized way, rather than being pulled by the most common locomotives. The most common locomotive traction mode is to rely on the power of the locomotive to pull the whole train, it can be said that the whole train is driven by fewer driving wheels, and in order to make more effective use of the traction power of the locomotive and prevent the wheels from idling, it is necessary to add a lot of weight to the locomotive, thereby increasing the pressure on the track surface, increasing the construction and maintenance cost of the railway.

The so-called power dispersion mode means that a drive device is installed on the wheels of each car of the whole train, usually an electric motor, so that the power of the train can be distributed to each car. In this way, the axle of each carriage can be used as the drive, and the heavy locomotive is no longer needed, so that the weight of the carriage can be greatly reduced, not only is it easy to accelerate and decelerate in the train and the smooth driving on the large slope line, but also can reduce the noise and vibration, greatly improve the travel comfort, at the same time, because the pressure on the rail surface is reduced, the construction cost is reduced again, and the economic benefit is also improved. Even when braking, the kinetic energy of the train can be converted back into electricity, which can save energy.

Su Huandong couldn't help but be even more moved, this jishu, he also noticed it when he was looking for the latest relevant information in the ministry after learning about the conversation between Fang Mingyuan and Su Aijun. The power dispersion mode mentioned by Fang Mingyuan is the power mode adopted by Japan's Shinkansen high-speed railway. Because of this model, the Japanese Shinkansen trains not only have a very sensitive acceleration and deceleration response, which can ensure that the five-minute interval can run without worrying about crashes, but also the weight of the carriages is 10% lighter than that of domestic trains. On the other hand, the **V high-speed train of the same period in France, due to the centralized power design driven by the locomotive at the front and the tail end, the train shook greatly during the journey and accelerated and decelerated slowly, so it could not run in a distance of only 5 minutes like the Japanese Shinkansen train.

"Can you tell me, then, how did you come up with this?" Su Huandong asked with a smile.

"What's so strange about this?" Fang Mingyuan's mind was racing, and he already had an idea in the blink of an eye, "Grandpa Su, I heard the teacher say that it seems that many military jeeps can be powered by four wheels, right?" ”

Su Huandong nodded, the jeep is four-wheel drive, which is nothing new, as early as the jeep of the US military during World War II, it was already like this. But what does this have to do with the dynamic dispersion model?

"The teacher said that the average car is powered by the rear wheels, and the jeep is more suitable for driving in the field than the average car, and its acceleration and turning are faster and more agile than ordinary cars, and the load capacity is also high, all because all four of its wheels can provide power. I thought, if a train had so many wheels, like a jeep, each wheel could provide power, then the speed would be faster, wouldn't it? Fang Mingyuan said with a wink.

"......" Su Huandong and Su Aijun looked at each other, speechless for a while, it was the first time they had heard someone explain the inspiration for the emergence of the power dispersion mode in this way.

At this time, the door of the living room suddenly looked, and a girl poked her head in and said, "Grandpa, grandma wants me to come up and ask you to go down to eat!" ”

PS: Many friends are asking, since he is a resource tycoon, where are the resources, and why haven't nearly 100,000 words of resources appeared. And some friends also mentioned it more sharply, thinking that if you want to become a resource tycoon in Huaxia, you are looking for death. All I can say is that you are confusing the meaning of resources and energy.

Resources are the general term for various material elements such as material, financial, and human resources possessed by a country or a certain region. It is divided into two categories: natural resources and social resources. The former are sunlight, air, water, land, forests, grasslands, animals, minerals, etc.; The latter includes human resources, information resources, and various material wealth created through labor. These can all be called resources.

And what about energy? There are currently about 20 definitions of energy. For example, the Science Encyclopedia says: "Energy is the resource from which energy such as heat, light, and power can be obtained"; The Encyclopædia Britannica says: "Energy is a term that includes all fuels, running water, sunlight and wind, which man can use by appropriate means of conversion to provide himself with the energy he needs"; The Encyclopedia of Japan says: "In various production activities, we use heat, mechanical, light, and electrical energy to do work, and various carriers in nature that can be used as the source of these energies are called energy." China's "Energy Encyclopedia" says: "Energy is an energy-carrying resource that can directly or through conversion to provide any form of energy required by human beings, such as light, heat, and power." It can be seen that energy is a source of energy that can be converted into each other in many forms. To be precise and simply, energy is a material resource in nature that provides some form of energy to humans.

Therefore, resources include energy, and energy is only a part of resources.

Although the protagonist is a person in the geological exploration industry in the previous life, he must be familiar with the distribution of mineral deposits in China, and naturally he will know many mineral deposits that were discovered in later generations. But at present, he is only seven years old, he has nothing at hand, no power, no money, no power, and now he is involved in energy, that is really looking for death, even YY can't find logic, everyone is willing to see such things? And it is true that as a friend said, it is better not to touch energy in China. So I can only say that the mineral deposits definitely want to have a place for zhan, but by no means now. And weishenme must be limited to the country?

And resources, in fact, the protagonist is already using resources, because information is also a resource. Because he experienced his previous life, he knew that there would be a severe crackdown in eighty-three years, monkey tickets would go up, trains would speed up, houses would go up, and those who bought stocks at the beginning would have a large amount of money, and they would have to charge for going to college!

Today I finally caught up with the second watch, I want tickets, I want to collect. The lord in the back is chasing too closely!
