Rising: Ten Thousand Years Chapter 149: : synchronous motor

A telescope.

Everyone was a little surprised.

The guests kept watching with the binoculars, and they found that the distant scenery was much closer.

"This is amazing."

"It's amazing."

"In this physics, it is simply uncanny workmanship."

"I didn't expect Jin Shiteng, a man from the white robe country, to have such academic attainments."

“…”

Jin Shiteng likes others to use his telescope, and he keeps trying to explain the principle. In order to explain the principle clearly, he has done many experiments. It took a long time to write a thesis, just for today.

There is no principle of secrecy in mind. Coming to this podium, there is no such thing as hiding anything.

After Jin Shiteng left the field, it was the next turn. This person was also a civilian scientist, and what he discovered was actually a chemical phenomenon to be precise.

"I have not discovered the principle of this discovery so far. Sorry, I really can't explain why."

Everyone was a little curious.

But I saw this person put an aluminum plate on the table, and then sucked out a drop of mercury from a glass bottle.

"Mercury?"

"What is this for?"

"Does the mercury come into contact with this aluminum plate?"

“…”

Under the watchful eyes of everyone, the man dropped a drop of mercury on the aluminum plate. A terrible phenomenon appeared.

However, I saw that the aluminum plate suddenly began to boil and corrode, and small bubbles kept popping out.

After a while, a bean-sized fibrous body suddenly grew on the part of the aluminum plate with mercury. Then, the fibrous body began to grow continuously and climbed higher and higher.

In just a dozen seconds, a thigh-thin, half-meter-high fibrous body appeared on the aluminum plate so quickly. It is simply a supernatural phenomenon.

"I don't know how to classify this experiment, and I can't explain why it's here for the time being. It's just a drop of mercury, but fibers the size of thighs grew out of thin air... When I came here to compete , In fact, I also want to solve this question. If possible, I hope Master Li can give me some answers."

After saying this, everyone looked at Li Zhen.

Ge Qingping was also full of doubts. He thought in his heart that this should be a chemical phenomenon. But there is no such weird thing in chemistry, aluminum plate, this kind of behavior will appear when it comes into contact with mercury? What is the principle.

A drop of mercury actually increased the volume of the entire aluminum plate. For no reason, a fiber tree more than half a meter high grew out. And when he put the aluminum plate on the scale, the weight actually increased.

For no reason, the weight will also increase? This phenomenon is unreasonable. That drop of mercury seemed to have summoned a giant beast in the air...

Everyone was in an uproar, looking at Li Zhen, wondering if Li Zhen could give an explanation.

Li Zhen smiled and stood up: "In fact, this phenomenon should be placed in the category of chemistry. It makes sense to say it is physics. Let me ask this gentleman first, what kind of phenomenon do you think it is?"

The man hesitated for a moment, and boldly said: "It should be a chemical reaction between the mercury and the aluminum plate. I named it the brush reaction."

Li Zhen shook his head: "Wrong, to be precise, there is no reaction between mercury and aluminum plate. There is no reaction between tribute and aluminum plate."

There was an uproar in the field, but no reaction? Why would such a giant grow out of no reason without generating a reaction? It's like a tall building rises from the ground.

"To know the principle of this, you must first understand the characteristics of mercury and aluminum plates. Among them, aluminum will dissolve in mercury, just like salt dissolves in water. And aluminum is a very strange metal, aluminum will be oxidized , and after the aluminum is oxidized, this kind of long hair and volume expansion will appear. To put it bluntly, as long as the aluminum is in contact with the air, this kind of brush reaction you said will appear.”

"That's not right, Master Li, then we used so much aluminum. The aluminum is exposed to the air like this, and this is not the case with aluminum."

"Because there is an oxide film on the surface of aluminum. This oxide film can protect the interior of aluminum and prevent aluminum from contacting with the air, thereby oxidizing. However, mercury directly destroys this layer of oxide film, causing a drop of water to be dropped on the aluminum plate. One point of mercury is oxidized, and the other point is oxidized by aluminum to form aluminum oxide. Aluminum oxide does not dissolve with mercury, so it floats out of the surface, forming the brush-like Fiber. As the aluminum oxide continues to emerge, more oxide films will be broken, more aluminum will be oxidized, and aluminum oxide will be continuously formed.”

"As for aluminum oxide, it can be called amalgam aluminum alloy, and this kind of fiber is amalgam aluminum alloy. It can also be called amalgam. It looks like a tall building rising on the aluminum plate, and it looks like It's like growing hair. This is the phenomenon of the brush reaction you mentioned... Strictly speaking, this is actually the phenomenon of mercury corroding aluminum. A piece of aluminum weighing several kilograms only needs to be contaminated with a drop of mercury, that is, mercury .In just ten seconds, this drop of mercury will corrode and destroy the entire aluminum weighing several kilograms, forming an amalgam.”

After speaking, Li Zhen sat back down again.

Everyone was stunned, especially the person who demonstrated this phenomenon was also full of admiration.

"Master Li really knows the past and the present, I really admire you."

"哗哗哗" applause continued to sound. Everyone has seen Li Zhen's knowledge.

This is the first time I have seen Li Zhen's knowledge so clearly. I used to listen to rumors and rumors. This time I understand why he is qualified to be the teacher of the Kyushu Academy of Sciences and the three departments. Why can one person teach the entire Kyushu Academy of Sciences.

Li Zhen pressed his hands and said with a smile: "Don't waste time. Next, let the students from the Electromagnetic Research Institute come up, they have new discoveries."

After Li Zhen finished speaking, Fang Hanxian, the dean of the Electromagnetic Research Institute, stepped onto the stage and smiled: "The scientific research achievement of our team is the idea of ​​alternating current."

"AC?"

Everyone asks, what is alternating current?

"In today's world, direct current is mainly used. You may not understand the difference between the two types of electricity. To put it bluntly, direct current is the electricity of dry batteries. And alternating current is 220V electricity. Alternating current is alternating current, the size and The direction of the current changes periodically with time. The direct current is the opposite. Our alternating current theory can theoretically lay the national grid, with greater power transmission and greater voltage..."

Fang Hanxian talked on the podium about the benefits of AC power~IndoMTL.com~ and the development of AC power in the future. And the theoretical assumptions and principles of alternating current, one by one.

Sitting in the judges' seat, Li Zhen was full of pride. My heart is full of expectations.

Once the alternating current is fully rolled out, the era of industrialization in Kyushu that I planned will be completely kicked off.

Everything now is just laying the groundwork for the future industrial age.

Obviously, the Institute of Electromagnetics does not only have the achievement of alternating current.

After Fang Hanxian stepped down, the vice president of the Institute of Electromagnetic Research also came on stage, and came up with a second result.

Synchronous motor.

When the vice president connected a fist-sized metal device to the battery, a miracle happened.

With a 'hum' sound, the metal equipment started to spin.

Everyone stood up with an exclamation: "This, how can this rotate?"

"It turned on when it was powered on?"

"If the power is higher, wouldn't this be a greater invention than the steam engine?"

"Using dry batteries, it can rotate?"

“…”

The vice president looked proud: "This is the second achievement of our Electromagnetic Research Institute, a synchronous motor. This is another application of direct current, and we can call it electromotive power. In fact, , in the research of our institute, we are now studying AC asynchronous motors. This needs to be applied to AC. Obviously, the power of DC motors is too small. According to theoretical assumptions, using more powerful AC motors, its electric power will be perfect Play out."
