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。
One-dimensional multi-group radiation transporter (RDMG) was used to simulate the spectral reconstruction of X-ray heated gold planar target. The obtained target surface emission spectrum was similar to Planck’s spectrum, but distorted near the peak area. Analysis shows that halo zone plasmas are optically thinner for the photons in the frequency band of the distortion zone. This region corresponds to the valley between the absorption coefficient spectrum N band and the O band absorption peak.
