| 摘 要： | 应用EGS4电子输运的蒙特卡罗程序，计算了在平等板空腔中均匀分布电子源的电子在不同壁材料空腔中沉积的能量，并与由电子输运球谐近似计算的结果进行了比较，表明在大部分情况下二者都符合得较好；同时建立了剂量学研究中重要的基础数据库。

| Abstract: | The energy deposited in a plane cavity is calculated by Monte Carlo technique, which is achieved by EGS4 program code. If there is a even elec tron source in a cavity, the energy deposition in the cavity will vary with many conditions, such as the energy of the electrons, the size of the cavity, the di fferent material of the cavity wall, et al. The calculation results are compared with the data which were calculated with the analytic method. And a basic data set is built for general dose calculations. |
