| 摘 要： | 用一维多群辐射输运程序(RDMG)对X光加热金平面靶的谱改造过程进行了数值模拟，得到的靶面出射谱与普朗克谱相近，但在谱峰区附近出现畸变。分析表明，晕区等离子体对于畸变区频段的光子是光性薄的。该区域对应于吸收系数谱N带和O带吸收峰之间的谷区。

| Abstract: | One dimensional multi group radiation transport program (RDMG) is used to simulate the process of X ray heating Au disk. It is found that although the outward spectrum from Au disk is near Planckian, the peak region is in some way deviated from Planck spectrum. This is due to the fact that the corona plasma is optical thin to the frequencies of peak region ,which is corresponding to the valley of the absorption coefficient spectrum between the peak of N band and that of O band. |
