【摘要】 分两篇介绍了近年来国际上出现的一种新兴材料——纳米碳管．第一篇介绍了纳米碳管的历史背景、物理性质和潜在应用价值，还介绍了与纳米碳管共存的另一类相关形态——石墨纳米颗粒．第二篇结合作者的研究结果总结了国际上当前对两种纳米碳管即直形管和线圈形管结构的电子显微镜研究，并对两种碳管的生产方法和生长机制也作了简要的说明．更多还原

【Abstract】 In this paper we review the development of the research of carbon nanotube a new attractive material appearing in the world In addition to its background , physical properties and potential applications , we present particularly, based on our own results , the structural studies of straight, as well as coiled, carbon nanotubes by transmission electron microscopy. Production and growth mechanism of these two kinds of carbon tubes are also described briefly.更多还原
