- 摘要:80年代以来, 南极上空出现的“臭氧洞”不仅引起了科学界, 而且引起了政界的震动.臭氧层的破坏, 将会给地面上的生物造成很大的危害.
- Abstract:HeI (21.22eV) photoelectron spectrum of microwave discharge(MD)spe-cies of CF2Cl2 has been reported in this paper. The HeI photoelectron spec-tra of reaction between O2 and the species generated by the MD of CF2Cl2,CF2Cl2 and the species generated by the MD of O2, and of the productions generated by the MD of CF2Cl2 and O2 mixtures have also been given. The chlorine atomic species was obtained by the MD method.So the mechanism of ozone depletion in the stratosphere by the Freon is presented.
