载气对富勒烯形成的影响

研究了Ｈｅ，Ａｒ和Ｎ２作为工作气体对富勒烯生成的影响．在一定的气压下，不同的惰性气体对富勒烯的产率及其组份有重大影响，相同的气体在不同的气压下也影响到它的产率．同时，气压处于低真空状态时（不充载气）得不到富勒烯，表明一定压力的惰性气体对富勒烯的形成是必不可少的，这对富勒烯形成机理的推测提出了一个新的影响因素．结合电弧的烧蚀方式对此作了分析和解释．

The Effect of the Atmosphere on the Formation of Fullerene

The effects of He, Ar and N2, as the working gas, on the formation of Fullerenes were studied respectively. The experimental results indicated that the different inert gases greatly affect both the productivity and the composition of Fullerenes and for the same gas the different pressures also affect the productivity. It was also found that no Fullerenes can be obtained without a working gas. It indicates that the gas of a difinite pressure may be necessary to the formation of Fullerenes. A new possible mechanism of the Fullerenes formation was suggested.
