2000年2月美国制定了 “国家纳米技术战略”，引起世界各国的巨大反响，日本、欧洲的工业先进 国家先后制定了纳米技术发展规划。纳米科技这一崭新的前沿学科，被视为新一轮材料革命的核心，在航空航 天领域将产生重大影响。文章综述了纳米技术的概念、纳米材料及纳米技术的研究情况。

In February 2000, U.S.A worked out the strategy of National Nanometre Technology (NT), which evoked worldwide repercussions . Japan and Europe also successively worked out their development program of NT. As a new forward branch of science , NT will become a core driving force of causing a new round of material revolution in the 21 st century and exert an immense influence on the field of aerospace. This paper simply introduces the definition of NT, nanometre materials, and the research and development status of NT.
