摘　　要：激光惯性约束聚变使用的玻璃微球经中子辐照后,产生辐射增强扩散效应,Ar在玻璃微球中的扩散性能显著改善,获得了常规加热加压扩散方式无法得到的扩散效果。而带电离子辐照玻璃微球后Ar的扩散性能却没有明显改善。研究了中子和其它带电粒子辐射增强扩散效应的差异。After being radiated by neutron, the glass microspheres, which used in ICF research, have greatly increased the ability of Ar diffusion in it because of the radiation-enhanced diffusion. Such results cannot be achieved by means of thermal diffusion. But after being radiated by charged particles, the ability of Ar diffusion in glass has not increased very much. The differences of the radiation-enhanced diffusion caused by neutron and ions are presented.
