影响C_（60）／C_（70）产率因素的研究

Studies on Factors Affecting the Production Rate of C_(60)/C_(70)

本文介绍了直流电弧法合成Ｃ６０／Ｃ７０技术，测量了在氦和氩中，烟灰产率和Ｃ６０／Ｃ７０提取率与气压及孤电流的关系，在１５０ｍｍＨｇ氦气氛和６５Ａ孤电流下，烟灰产率为３４％，从烟灰中提取Ｃ６０／Ｃ７０的产率为１７％。

C60/C70 synthesis technique by using DC arc is presented in this paper. The production rates of soot and the extraction rates of C60/C70 from soot as a function of atmospheric pressure and arc current in helium and argon have been measured. Under the conditions of 150 mmHg pressure of helium and 65 A arc current, the production rate of soot was 34% and the extraction rate of C60/C70 was 17%.
