Since the discovery of vacuum by Torricelli, the vacuum range has evolved from a very low vacuum to a very high vacuum. However, people have not developed a pump that pumps a container from the atmosphere to a vacuum or ultra-high range.
Since 1643, vacuum tools have been used to reduce or maintain the gas density or gas pressure in the vessel, which is more or less below the ambient atmospheric pressure. The development of vacuum pumps to the 20th century is only two basic types. One is the gas “transport†and the other is the gas “captureâ€, which can be referred to as *1+1* vacuum acquisition technology.
1 The natural laws of vacuum Physics is the classic of science. They include the laws of nature. With these knowledge of natural laws, people can better understand nature.
The ancient "vacuum technology", the "vacuum" of modern physics, the "artificial vacuum" and the "natural vacuum" all follow the same laws. These different concepts can be represented by the same mathematical formula: where: V represents a specific "space" volume â€
X represents a specific state "space" or "volume"
(U) represents the physical behavior under a particular "space."
A represents the result of the physical behavior under a particular “space†and the end of the “vacuum†of modern physics when X*0, ie “space†approaches infinity, microscopic “vacuum†research.
In modern physics, the concept of "vacuum" is derived from the study of the quantum laws of the field. The physical content represented by the concept of "vacuum" is not the original meaning of the "vacuum concept." Therefore, the concept of vacuum itself is not very important. People do not care whether it is a "fake air" or a "vacuum," nor do they argue and pursue this point. What people are concerned about is the existence of the physical content of "vacuum" and the connotation of vacuum. The evolution.
When the X* constants, namely the specific space for the study "artificial vacuum" and "engineering vacuum."
The application of vacuum technology in ancient times was carried out in a specific small volume, which can be expressed as *M*. Limit ") to obtain "vacuum" and in the "vacuum" environment for process fabrication, measurement analysis and scientific experiments and other required theories and Its applications include the use of pressure differentials, the elimination of interference from electrons or molecules passing through space, and the reduction in the number of times particles hit the surface.
In a specific (limited) space, due to different requirements, the degree of vacuum required is of course different. In a specific space, the characteristics of vacuum technology determine that it is an energy-saving technology that helps improve quality and helps protect the environment. The technology will help raise the national defense force. In the 21st century, vacuum technology will have a new significance in the development of new disciplines.
When "space" approaches infinity, the study of the macro-world can be expressed as: a cloud of air in the natural world can simulate an infinitely large pocket (ie infinitely large space). A lot of air has very significant homogeneity. Extending several hundred kilometers to hundreds of thousands of kilometers, people call them air masses. The level of a single air mass ranges from one million square kilometers to a vertical height of 10 kilometers. The temperature and humidity of the air mass are not always constant, but the change is very small. The atmospheric pressure can fluctuate in a small but obvious range, flowing naturally from a high pressure pocket (cold air mass) to a low pressure pocket (warm air mass). Changes in atmospheric pressure cause the formation of winds. Due to the rotation of the earth and the circulation force, V 2 can be infinitely increased in a given space in a small area on the Earth (V 2000 emissions of 14 million tons and S02 emissions of 23 million. Tons, iron and steel plants, power plants, non-ferrous metal smelters, chemical plants, and cement plant chimneys are artificial mantles of “vacuum pumpsâ€. The greater the pumping speed, the more 670 tons per hour of boilers, and the measured smoke emissions of 1.6 million tons. M/h3=4. 45Father 105L/s At present, the maximum pumping speed of vacuum pump at home and abroad is: L/S Cooling pump: up to 16L/s If the volume is 1X10V*1X10W, how to obtain vacuum, given space Now that (V) is increasing, we give us the conventional *1+1* variable volume method and the condensate adsorption method. The vacuum acquisition technology is difficult to meet, and it is impossible to meet the requirement of unlimited increase in the “space.†How to use the “new methodâ€, “ The new principle "to adapt to the project" space "infinitely increases. It is the vacuum to obtain the work goal to be solved.
3 (V and the earth is a "natural vacuum" manufacturing factory. Every day new vacuum technology is created. This state is dynamic, always renewed, destructive, exciting, and sometimes beautiful.
All the atmosphere around us is attracted by the gravity of the Earth. The atmosphere can also be compressed. It is already in the atmosphere where the upper atmosphere will compress the lower layers, and the lower atmosphere will be denser. The atmosphere on the surface of the Earth is the most compressed and densest. On the contrary, the higher the atmosphere is, the lower the density of the atmosphere is.
High pressure density is relatively small pressure fluctuations will cause great differences in atmospheric types, instantaneous pressure changes make the air rapidly transported 104960.4 (Pa), in the artificial vacuum in the specific "space" two gases interdiffusion, mutual migration, and even the container "space" The relative concentrations are all the same and the diffusion direction is from the pressure-reducing end to the low-pressure end.
Natural Himalayas turned out to cut off the warm currents of the Indian Ocean, causing drought in North Asia and flooding in South Asia. China alone has more than 3 million square kilometers of dry areas, while South Asia suffers from frequent flooding, the Himalayan plateau is low pressure, and the Gobi Desert is a strong high pressure. . Due to the Earth's suction earth topography and the atmosphere “V is too complex, gas cannot form an air flow.
Nature will continue to alarm the world because the behavior of nature is often unpredictable. But after these scenes, he is basically neutral, that is, neither good nor bad, that is not destructive, nor constructive, and naturally does not arrange disasters. He only follows his own rules. The problem is that nature is sometimes too powerful, and the atmosphere is made up of a bunch of gases. *V The "vacuum technology" of human development has 361 years of mileage (in popular terms). It has promoted the development of society as an independent discipline. Vacuum technology has successfully set up a span. Bridge between science and technology. It plays a substantial role in the development of science and technology in almost all frontier areas.
Vacuum technology continues to exist as an important subsidy in the 21st century. Therefore, the problem is not to improve autonomous research or achieve a certain technology, but to devote to the independent basic research of the discipline.
In the 21st century, vacuum technology will not be *1+1*Gade's variable volume method and Langmuir's "adsorption method".
More new theory and design will be produced to meet (V. On tens of thousands of meters, the powerful airflow is a large row of fans. Once this kind of exhaust effect is generated, the air pressure on the ground will decrease. The pressure of the air is different, and it gradually generates a circulation, and gradually produces a low pressure area, that is, a major rain-making, snow-making person.Naturally uses its own energy to create a "low vacuum pump."
Earth is the manufacturing plant of the storm. It creates new monsoons every day, hurricanes or typhoons, tornadoes and storms.
Due to the uneven heat between the equator and the polar region, a large amount of energy is released. The energy generated by a thunderstorm is equivalent to hundreds of nuclear explosions, and this generation process has never stopped.
Is the vacuum full of space between matter and antimatter? Can a vacuum phase change produce tremendous energy in an instant? In the 21st century, humans will use “natural energy†to make “optical pumps†(solar) fission pumps?
(Atomic fission) "charge pump" (gas power) and so on.
We should leapfrog old concepts and the shackles of old theories to welcome the future. The ultimate goal of any science is "prediction". Let us work together to explore the vacuum "space" from infinity in infinity trails, and grasp the evolution of the connotation of "vacuum" (ie 0*X revolution and development of old theories). It will also influence people’s theory of the “vacuum†concept. In turn, people’s research on the concept of “vacuum†will also promote the development of society.
What role does "vacuum" play in human survival and sustainable development in the 21st century? Can a "natural vacuum" behave like an intrinsic volume (V=CnSt) "artificial vacuum"? Humans can drive freely and change themselves, for the benefit of their children and grandchildren? The sustainable development of future generations and society allows us to work together to explore the mysteries of vacuum!
