在世界新技术革命中,信息、能源和材料是优先发展的三大领域。从七十年代起,西方国家把材料、能源、信息列为战略重点、发展高技术的三大支柱。有人讲,在发展国民经济整体中,能源是“血液”,材料是“骨肉”, In the world’s new technological revolution, information, energy and materials are three major areas that give priority to development. Since the 1970s, the western countries have listed materials, energy and information as their strategic priorities and the three pillars of high technology. Some people say that in developing the national economy as a whole, energy is “blood”, the material is “flesh and blood”
