Do you know that Japan has three world-leading technologies. This country is not as large as a province-large island country in my country, but their technology is very advanced, and in some aspects it is even ahead of the world, becoming the only developed country in Asia. Today we will talk about what are the three major technologies in Japan? How big is the gap between my country's scientific and technological level and Japan?
First of all, I want to talk about Japan's machine tool processing technology, Japan has the most accurate machine tool processing technology in the world. In this field, Japan is several times ahead of the United States. When the United States produced the F22 Raptor fighter, the parts on the fighter were all made by Japan's ultra-high precision machine tools. In addition, these high-end mechanical manufacturing and processing technologies in Japan are all from Japan, including mechanical design solutions and raw materials. Therefore, they have formed a very complete technology industry chain, and the quality of is the most guaranteed.
In addition, Japan's high-precision components are made of wire cutting technology. It is said that the machining accuracy of each machine can reach 0.001mm, which is very difficult for other countries, but Japan can do it. With such technology, they don’t have to worry about rising prices or not being able to buy raw materials in the industry, and they don’t have to worry about external pressure at all. Therefore, Japan can be said to have won processing orders all over the world.
This also led to Japan's technological blockade on other countries. In addition, they have very strict requirements on mechanical processing and manufacturing, and they set the accuracy of the equipment very accurately. This is also the reason why Japan's machining and electronic equipment are ahead of other countries.
Japan has three world-leading technologies. The second is their single-crystal blade material. You may not have heard of single-crystal blade material. This is a key accessory for turbine engine . What we need to know is that the most important component of a turbine engine is the turbine blades. Because the principle of this kind of engine is that the blades rotate at high speed, absorbing the surrounding air to generate thrust. This blade can be found at gas turbine at about 1600 degrees, which is the largest experimental single crystal dynamic blade in the world in the late 1990s. It is generally mainly used on aircraft, rockets and some large ships using natural gas .
turbo blades have very harsh working environments in the engine. They not only need to have a high adaptability to temperature changes, but also have very complex stress conditions. It is also the weakest part of the entire engine. The blades also need to be able to withstand the huge centrifugal force of when the engine starts up. Therefore, in this working environment, the selection of blade material is very important. The research on material requires a series of strict requirements. This technology is unmatched by other countries.
The third one is their proton number radiation therapy accelerator. We all know that cancer is the deadliest disease in the world. Because it has a long incubation period and will spread and metastasis, it is a headache for medical experts around the world. During the traditional radiotherapy process, after the radiation enters the human body, the radiation energy of will gradually kill cancer cells through the skin. But in this process, a large number of human tissues and beneficial cells will also be damaged, while proton number radiation therapy will not.
During the treatment process, it can not only destroy the work of other normal cells, but also directly destroy cancer cells. Therefore, proton therapy has become an important cancer treatment method in Japan, and this method has also played a very important role. It is worth mentioning that although there are proton number radiation therapy accelerators used for radiotherapy all over the world. But most of the origins are produced in Japan.
After talking about Japan’s three world-leading technologies, how big is the gap between my country’s technology level and Japan?
Today, the world's technology, the United States, Germany, the United Kingdom, etc., are in the world's first echelon. The scientific and technological level of our country and Russia should be in the second echelon. So our scientific and technological level is about ten years behind developed countries in some fields., especially compared with developed countries such as Japan, Germany, and the United States, the scientific and technological level is still far higher than ours in some aspects. But this is just a certain field. If we look at it overall, such as heavy industry, military industry, and cutting-edge technology, then our country is at the world's leading level.
Today, with my country's rapid development of strength, the gap between my country and the world is gradually narrowing. In the past, China's technological breakthroughs were just individual breakthroughs. But in recent years, many projects in the world are inseparable from China! The same is true in the field of science and technology. At present, China is the only country in the world that has all the industrial categories in the United Nations industrial classification and the country with the most complete industrial chain. There are 40 major categories, 200 medium categories and 526 minor categories, all of which are available. For example, communication, nuclear power, artificial intelligence , 5G, etc. They are all at the world's leading level.
Although Japan's technology is better than China in some fields, it is only a few after all. Moreover, Japan is now in a weak position, and in the future, Japan may become a supplier of spare parts in other countries. Japan's technology has reached its limit, and it is also the glorious period of Japanese technology. At present, my country's comprehensive strength is nowhere to be surpassed by Japan.
Finally, time is on our side, our country has just made efforts and is rising rapidly. Although there are some fields and the world, with the continuous efforts of our scientists, the future potential is still great.
OK here is Xuxu Science Popularization. Press and like it for a long time, good luck will happen~!
