摘　　要：介绍一种利用自制实验装置,测量经过不同辐照剂量老化的硅橡胶材料的热释光(TL)测量结果,并用自动分峰技术分解谱图.结果表明,热释光(TL)谱具有复杂的能级分布,其分布宽度近似为0.19-0.34eV,受陷载流子的初始分布函数偏离高斯型.频率因子与陷阱深度呈近似线性关系.We introduce actual test results of Thermoluminescence(TL) of silicone rubber radiated for different doses by a experimental set-up home-made in the article. The TL curve between luminous intensity and temperature is analyzed by using auto-separating method. The results show that the distribution of trap energy level is complex, the ranging of trap depth is 0.19 -0.34eV, the initial carrier concentration distribution in trap is deviated from Gauss type, and the relation of frequency factor and trap depth is approximately linear.
