尖端技术时代的主要支柱是新型原材料的开发。目前世界各国研制新型材料的动向如下。 1.超导材料(钛—铌合金等) 这种材料在超低温条件下电阻接近零,在常温下比普通金属的电阻高。可应用于运输、机电、情报传送系统等。 2.非晶体材料将金属从熔融状态以十万度C/秒以上的速度超速冷却,使其来不 The main pillar of the cutting-edge technology era is the development of new types of raw materials. At present, the trend of developing new materials in various countries in the world is as follows. 1. Superconducting materials (titanium - niobium alloys, etc.) This material in the ultra-low temperature resistance close to zero, at room temperature than ordinary metal resistance high. Can be applied to transport, electrical and mechanical, intelligence delivery system. 2. Non-crystalline material will be metal from the molten state at a speed of one hundred thousand degrees C / s over speed cooling, so that it does not come
