摘　　要：利用D-T中子对氧化钍圆柱装置进行了辐照。样品直径为30 cm、厚度为15 cm。在不同的布局状态下,采用芪晶体闪烁体基于反冲质子法对1 MeV^15 MeV中子能谱进行了实验测量;基于反冲电子法对中子辐照下和辐照后的0.5 MeV以上伽马能谱进行了测量。对能谱中的分布规律、与布局状态的关系进行了比对分析。The cylindrical assembly of thorium oxide was irradiated by D - T neutrons. The Diameter of the assembly is 30 em while the thickness is 15 era. The neutron spectra of 1 MeV to 15 MeV were measured with stilbene using recoil proton method in several arrangements and the gamma spectra with energy above 0. 5 MeV were also measured using recoil electronic method. The comparison and analysis were finished referring to the structure of spectra and its relationship with arrangement.
