当前,国际上公认的高技术领域,包括生物技术、航天技术、信息技术、新能源技术、新材料技术和海洋技术等,而新材料技术被誉为“高技术的基础”。正因为如此,世界各国特别是发达国家,都把新材料技术摆在国家特殊的战略地位。比如,美国自从80年代中期以来,每年耗资10亿美元,重点研究开发金属复合材料、超合金、高温 At present, the internationally recognized high-tech fields include biotechnology, space technology, information technology, new energy technology, new material technology and marine technology, etc., and new material technology is honored as “the basis of high technology.” Because of this, all countries in the world, especially the developed countries, put the new material technology in a special strategic position in the country. For example, the United States has spent about $ 1 billion a year since the mid-1980s, focusing on research and development of metal composites, superalloys, high temperature
