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d6mm碳棒),150±10A(对d8mm碳棒)和200±10A(对d10mm碳棒);产率与碳棒直径无关。

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. 7×10³～6.7×10³pa current 100±10 A( for d 6 mm rod)150±10 A( for d 8 mm rod)200±10A(for d 10 mm rod)
