| 摘 要： | 提出了一种双温度区(光斑区和腔壁区) 模型, 这种模型可以在满足能量平衡方程的同时提供一种估算辐照不均匀度各阶球谐展开的简单有效的方法。这种方法用于分析平面靶放置在腔壁侧面中段的腔靶辐照不均匀度的各阶球谐展开。计算表明, 在各阶不均匀度中以l=4,m=2的均匀度最大。由光斑分布带来的不均匀度是产生平板辐照不均匀度的主要原因。

| Abstract: | A two temperature model is proposed to deal with radiation uniformity.This model can provide pre estimate of radiation uniformity of laser configuration.It can deal the configurations whose geometrical structure make them very difficult to deal with by numerical simulation.The model is used to analyze the radiation non uniformity of planar target in hohlraum.It is found that the l =4, m =2 non uniformity is the most dangerous one. |

| Keywords: | radiation non uniformity planar target |
