When he was off work, Tao Decai came to see Duan Zhu.
After talking for a while, Tao Decai said, "Can't this thing be mass-produced?"
Duan Zhu said: "Yes, I said it at the press conference. Maybe its application value is not high. We try to find out its research value."
"That's because I misunderstood. I thought that you can already communicate with it and control it to change the light path. You know the people from the Institute of Optics and the Institute of Mechanical Engineering. You can study some of its constituent materials and then imitate them. Is that enough?"
Duan Zhu said: "It is currently handed over to the Institute of Optics for research. The results have not been released yet."
A few more days. Duan Zhu asked Gu Xina if he had studied the substance of the stone.
Gu Xi said: "This may be a meteorite. An alien object from the sky. I can't figure out what kind of material it is."
Duan Zhu said: "Okay. Do you think you can help me find an investment company?"
Gu Xi said: "I will help you handle this. It's almost time, wait a few more days. Find someone more reliable."
A few days later, Tao Decai came to Duan Zhu and asked, "How is their research going? Is there any substance that cannot be recreated?"
Duan Zhu said: "The composition of matter cannot be determined. That is to say, this element cannot be found on the earth, and there is no way to recreate it."
Tao Decai said: "Oh. That's a pity. I've seen your video introducing the use of it for rapid manufacturing. I originally wanted to use this method to manufacture parts in large quantities."
Duan Zhu said: "With the current manufacturing capacity, parts manufacturing speed is already very fast. Where else do we need such manufacturing speed?"
Tao Decai said: "Nowadays, during the construction of the new city of Shengshi City, many rapid construction buildings require large quantities of parts."
Duan Zhu said: "What about ordering?"
Tao Decai said: "The price is high. There are several mining areas next to Licheng, which are rich in metal resources and can be obtained locally."
Duan Zhu said: "Then if we develop a new manufacturing method, we will contact you."
Tao Decai said: "Okay."
In fact, Duan Zhu had no hope for new manufacturing methods. After all, he had little research experience, and the new methods ahead relied on that stone.
Once when he was working in a factory, the worker next to him said to him, "My name is Pu Lei."
Pu Lei said: "I am also a worker here.".
Another lady said, "My name is Peng Qing."
"I heard that you picked up a magical stone."
Duan Zhu said: "Oh, we all know this, but it is quite troublesome for us. After all, it is something picked up, not made by ourselves, so it is of no use."
Wu Tian concluded: "So everything that is not made by oneself is a toy."
"Let me tell you something." Peng Qing said mysteriously, "There are other magical stones picked up in the mining city."
Looking at her expression, Duan Zhu was a little scared, and his hair stood on end.
Duan Zhu said: "Have you seen it before?"
Peng Qing said: "I heard this. I have friends over there in Mining City."
Duan Zhu said, "Tell me what it's like."
Peng Qing said: "At that time, they were in the mine and found that it was hotter in one place and cooler in other places. It was warm in winter and cool in summer underground, and the temperature was basically 17 to 19 degrees Celsius. But they felt that it was hotter in one place."
Wu Tian said: "It's hotter. Is that magma?"
Peng Qing said: "The detector has measured that there is no magma."
Wu Tian said: "What kind of lift equipment motor is it?"
Peng Qing said: "There is none nearby."
Wu Tian said: "Is there a boiler? Is there air conditioning?"
Peng Qing said: "There is no air conditioning."
Wu Tian said: "That's impossible to guess."
Peng Qing said: "It's the stone I'm going to talk about. The heat near the location of this stone is relatively large, while other places in this space are very cold. It seems that all the heat is attracted to it."
Duan Zhu said: "Then it was picked out from the magma, right?"
Peng Qing said: "Someone later changed its direction and found that the location some distance away from it became hot."
Duan Zhu said: "This is strange enough."
Wu Tian said: "Yes, the heat source should be in contact with the temperature field, so that the heat can be transferred. How does it transfer heat across the air?"
Peng Qing said: "Transmission through the air. Yes. It's like putting the boiler aside. The people closest to it should feel the heat, but the people closest to it don't feel it. People far away feel the heat instead. The place in the middle It’s like jumping over.”
Duan Zhu said: "Is that a wormhole? Go through one wormhole, pass through the middle, and come out of another wormhole. But this crossing is only a few meters away."
As they turned, the temperature was originally the highest in the west, the lowest in the east, north, and south, and the temperature in the middle was moderate. After the direction of rotation, the temperature in the middle is cooler, the temperature in the east is cooler, and the temperature in the north and south becomes higher. Turning the direction again, the temperature is cooler in the middle, warmer to the east, moderate to the north, and south.
This does not comply with the law of gradual changes in heat. Heat change and distribution are completely controlled.
Wu Tian said: "Is this the content of thermal physics major?"
Duan Zhu said: "Maybe so. Who should I go to ask?"
Wu Tian said: "What kind of physical phenomenon does this belong to? Heat transfer?"
Heat transfer is a physical phenomenon that refers to the transfer of thermal energy due to temperature differences. In heat transfer, heat is used to measure the change in the internal energy of an object. There are three basic forms of heat transfer: heat conduction, heat radiation and heat convection. As long as there is a temperature difference within an object or between objects, heat energy must be transferred from high temperature to low temperature through one or more of the above three methods.
Wu Tian said: "Then let's check what the heat transfer is about first."
Heat conduction refers to the phenomenon of energy transfer occurring through the microscopic vibration, displacement and mutual collision of molecules, atoms and electrons within the object when there is a temperature difference between different objects or within the same object. The internal heat conduction mechanisms of materials in different phases are different. The heat conduction inside the gas is mainly the result of the irregular thermal motion of the internal molecules as a result of mutual collisions; in non-conductive solids, they vibrate near the equilibrium position of their lattice structure and transfer energy to adjacent molecules to achieve heat conduction; while metallic solids The heat conduction is accomplished by the movement of free electrons between the lattice structures.
Wu Tian said: "The most important thing is that the irregular thermal motion of internal molecules is the result of mutual collisions. The molecules that transfer heat are in contact with each other. They cannot be transferred across the air."
Thermal radiation, the phenomenon that objects radiate electromagnetic waves due to their temperature, is called thermal radiation. All objects with a temperature higher than absolute zero can produce thermal radiation. The higher the temperature, the greater the total energy radiated. The spectrum of thermal radiation is a continuous spectrum, and the wavelength coverage range can theoretically range from 0 to infinity. General thermal radiation mainly spreads by visible light and infrared rays with longer wavelengths.
Duan Zhu said: "Then there may be no contact between the thermal radiator and the material. For example, there is no contact between the sun and the irradiated object."
Wu Tian said: "I also heard that the temperature can be increased very high, reaching 1,500 degrees, and it can be used to make steel."
Duan Zhu said: "What kind of magical stone is this? Doesn't it mean that there is no need for a steel-making furnace?"
Wu Tian said: "Is the temperature of many points being superimposed? For example, if the temperature is 25 degrees nearby, there are 60 areas, and if superimposed 60 times, it will become 1,500 degrees."
Duan Zhu said: "Then how do you divide the area? If you divide it into 600 points, it doesn't mean it is more superimposed."
Peng Qing said: "Yes, it depends on how many times you subdivide it."
Wu Tian said: "How many treasures have been unearthed in this mining city."
Peng Qing said: "There are also various legends, but I won't mention them. There is no basis for it. The one I remember clearly is this stone that controls the distribution of heat."
