【摘要】 研究了用电弧法生产富勒烯（ｆｕｌｌｅｒｅｎｅ）的条件。通过实验，分析了石墨棒的直径、电压、起弧电流和氦气压力对产率的影响。得到生产富勒烯的最佳条件：电压２５～３０Ｖ；氦气压力２．７×１０３～６．７×１０３Ｐａ；电流１００±１０Ａ（对６６ｍｍ碳棒），１５０±１０Ａ（对６８ｍｍ碳棒）和２００±１０Ａ（对ｄ１０ｍｍ碳棒）；产率与碳棒直径无关。更多还原

【Abstract】 The condition for the preparation offullerenes was studied using the graphite- plasmadischarge method.Four factors were considered : diameter of graphite rod, voltage,electriccurrent, and the pressure of helium. An effective condition was obtained as follows:voltage 25～30V pressure of He 2. 7×10￣3～6.7×10￣3pa current 100±10 A( for d 6 mm rod)150±10 A( for d 8 mm rod)200±10A(for d 10 mm rod)更多还原
