利用一维多群辐射输运程序，数值研究了平面Au靶入射流强度对再发射谱、再发射流、反照率及边界等效温度的影响。当入射流强度在（0．12-1．2）×1014Wcm2范围内，发射谱接近平衡谱，但在峰值附近谱形发生畸变。随着入射流强度降低，发射谱偏离平衡谱越来越大。分析表明，这与烧蚀深度和冕区光学厚度变小有关。还给出了在不同入射流强度情况下反照率及边界等效温度随时间变化规律和对吸收流及再发射流脉冲的分析。

One dimension multi-group radiation transfer program was used tosimulate the processes of re-emission for Au disk. Some results about the re-emission spectrum, the re-emission flux, the albedo and the equivalent temperature at the boundary are given, and the variations of re-emission spectrum with the incident flux are analyzed. It is found that the re-emission spectrum is closely related with the depth of ablation and the optical thickness of corona plasma．
