摘　　要：本文详细讨论了石墨电弧法人工合成巴基管的工艺，优化了工艺参数。通过ＨＲＴＥＭ观察，探讨了巴基管的生长机制，认为其生长主要与碳原子微团簇有关，且强烈地受工艺参数影响。Ｘ射线结构分析表明，巴基管为密排六方晶体结构，ｃ／ａ＝２．７８６，相邻管间距为０．３４３ｎｍ。In this paper,the fabrication processes of buckytubules by operating an arc-electric graphite equipment were discussed in detail ,and the process parameters were optimized as wel.By HRTE M observation,the growth mechanism of the buckytubules were surveyed,and its growth was believed to relate to the carbon micro-clusters and severly infulenced by the process parameters. X-ray experimental results indicated that this kind of buckytube is a hexagonal close packed structure with c/a=2.786, the neighbour sheets of the tube are spearated by a distance of 0. 343nm.
