材料在人类历史上一直起着极为重要的作用,是人类社会进步的里程碑。新材料的出现和使用,往往包括技术进步、新产业形成,给经济、社会的发展带来重大影响。事实上材料科学的进步决定着国民经济中关键部门的增长速度,所以一切高新技术的发展都必须以新材料为基础和先导。当前的新材料研究与开发,对90年代直至二十一世纪的高技术和经济发展都起着关键作用。在国际技术经济竞争日趋激烈的情况下,能否掌握和应用新一代材料的生产技术,并在开拓和占领这一领域的世界市场中占据应有地位,对于一个国家的经济实力,乃至综合国力和国际地位,无 Material has always played an extremely important role in human history and is a milestone in the progress of human society. The emergence and use of new materials often include technological progress and the formation of new industries, which have a significant impact on economic and social development. In fact, advances in materials science determine the growth rate of key sectors in the national economy. Therefore, all high-tech developments must be based on new materials. The current research and development of new materials plays a key role in the high-tech and economic development of the 1990s and the 21st century. With the increasingly fierce international technological and economic competition, whether it can grasp and apply the production technology of a new generation of materials and occupy a place in the world market for developing and occupying this area should be well placed for the economic strength of a country as well as its overall national strength And international status, none
