    Roztosky looked at Gao Yang and said slowly: "So, what are the chips that are really useful to you? It's the basic materials."

    Gao Yang really didn¡¯t understand this. He asked curiously: ¡°Basic materials?¡±

    Roztowski nodded and said: "Yes, contact materials. For a country, especially an industrial country, basic materials are the most important, especially metal basic materials. This is the industrial base of a country.  , high-end equipment manufacturing industry is the industrial crown of a country, but you have to have the materials to form this crown."

    Gao Yang nodded in understanding, while Roztovsky continued to smile: "China has developed rapidly in recent years, and the research progress of gas turbines is not slow. However, some key parts still need to be imported from Ukraine.  Why?"

    Gao Yang shook his head, indicating that he didn't understand.

    Roztowski smiled: "Because there is a lack of basic technology at certain key points, the basic materials industry requires heavy investment and long-term research to achieve some results. Having money to invest is one thing, and more importantly, it requires  Time, and people who don¡¯t know much about it can¡¯t see the results and think it¡¯s a useless industry. Huaxia has developed rapidly in recent years. It stands to reason that Huaxia can use reverse engineering technology to make any complex equipment, such as  The development of aviation engines in China has been troubled over the years, but why is China suffering from such troubles?"

    Gao Yang whispered: "I really don't know how important the basic material is, because I didn't understand it before."

    Roztowski smiled: "Let me give you an example. Once, I was assigned to obtain the key technology of an American engine. In the end, we got a turbofan engine back and handed it over to one of our institutions for reverse engineering.  Research, at that time, the direction of technological development was already very clear. On fighter jets, turbojet engines would be replaced by turbofan engines, so the engine I was ordered to bring back was highly valued. They copied that engine, but in the end you  Do you know what the result is?"

    "What's the result?"

    Roztosky shook his head and said with a hint of helplessness: "They copied that engine perfectly, but the power of the engine is two levels lower than the original. Why? Because the rotor material of the turbofan is not up to standard.  Because the blade material of the turbofan is not strong enough to withstand ultra-high temperature and pressure, full power output will cause damage. If you actively reduce the output power, you can barely use it, but the performance is two grades worse than the original product."

    Gao Yang nodded and said loudly: "So that's how it is. However, since we have obtained the real thing, can't we just use the same materials as the real thing? Isn't metallographic analysis difficult? I don't understand this, so don't laugh."

    The black devils all laughed.

    Grevatov smiled and said: "That's not the case. It's not as simple as you think."

    Roztosky smiled and said: "Let me explain it. For this kind of high-end metal material, even if you get the physical object and can analyze the specific ingredients, but even if you use the same material, it will still be the same."  You can¡¯t achieve the same effect.¡±

    Roztosky waved to Grevatov: "Give me a piece of paper and a pen, and I will explain it to him."

    After taking the paper and pen, Roztowski drew on the paper and said with a smile: "The same material, different manufacturing techniques and different processes will have completely different performance. For example, let me give you the simplest example.  For example, a certain kind of steel contains iron, nickel, chromium, tungsten, and manganese, just to name a few materials. You obtain the physical object and know its composition through analysis, but you don¡¯t know where the tungsten component should be.  When to add it? To put it simply, the key part of the casting process is to add all the materials together? Or add nickel when the basic material iron is 1,000 degrees Celsius, and then add manganese when it is 1,200 degrees Celsius, or vice versa.  Woolen cloth."

    Gao Yang said stupidly: "Is it important?"

    Roztowski nodded: "Yes, it is very important, very important. A small difference may lead to a huge difference in the performance of this material. There is no mistake in the research of basic materials. Failure in one direction."  It could mean success in another direction, and sometimes a material with superior properties may just be luck, and it's really just luck that leads to the discovery and use of a completely new material."

    Gao Yang sighed: "It's so complicated."

    Roztowski smiled and said: "It's really complicated. It requires long-term investment, no output for a long time, and it also requires a lot of money. To be honest, the research of basic materials, especially high-end basic materials, is  Burn money.¡±

    "Glevatov said calmly: "The aircraft engine usesA certain material in ?? is composed of at least dozens of alloys, and the amount of some components can only account for less than one ten thousandth. However, without this material, the performance will be completely different, so unless you can get the information about this material  Only when all the production materials are available can we obtain materials with similar performance. As for the exact same performance, it is impossible, or it may be better, or it may not be as good as the original product. Why?  Because this involves another big area, which is the issue of manufacturing process level and purification process level. This involves a series of problems, which are very complicated.  "

    Roztosky smiled and said: "So, no matter how fast China develops and how rich it is, sometimes it has to be subject to some seemingly inconspicuous problems, because when it comes to high-end basic material problems, you can only slow down on your own.  Study slowly, try slowly, experiment little by little, and this takes time.¡±

    Grevatov said expressionlessly: "Just like the service life of the Soviet fighter jet engine is one thousand hours, while the service life of the American engine is more than 10,000 hours, this is a different understanding of war, and also a different understanding of equipment.  It is the result of different usage and research concepts. However, if the service life can be increased without being too expensive, we certainly hope to extend the interval between overhauls and increase the service life, but it is not possible. The materials are not as good as those in the United States, and the Soviet Union is using titanium.  In terms of alloys, it has surpassed the United States. For example, titanium alloys are used to make nuclear submarines. The United States is not as good as the Soviet Union. Is the U.S. national power inferior to the Soviet Union? Is the U.S. technology not developed enough? None, they just haven¡¯t found the right direction yet. Maybe one day, they suddenly  That¡¯s it, because they got a breakthrough.¡±

    Gao Yang nodded repeatedly and said: "Thank you for your popular science. Now I understand. In other words, I should start in this area?"

    Roztovsky nodded and said: "Yes, you should pay attention to this aspect, and you are lucky, because I can tell you what are the really good things in Ukraine, especially the good things that are suitable for you." (Remember.  Website address: www.hlnovel.com
