基于流体力学方程的自相似解，分析了激光加热金腔中的辐射约束。该分析被扩展到包括通过空腔中的孔的辐射损失。还考虑了腔内壁上的转换层对测量的辐射有贡献的可能性。与用Asterix碘激光器分别在0.44和1.3个/mU/m波长下进行的实验结果进行了比较，结果与理论预测符合得很好。比较的主要困难是缺乏关于激光转化为X射线的详细信息，特别是在1.3-/亩/米的实验中。
Radiation confinement in laser-heated gold cavities is analyzed on the basis of self-similar solutions of the hydrodynamic equations. The analysis is extended to include radiation losses through holes in the cavity. The possibility that a conversion layer on the inner wall of the cavity contributes to the measured radiation is also taken into account. The comparison with experiments performed at laser wavelengths of 0.44 and 1.3 /mu/m with the Asterix iodine laser shows reasonable agreement with the theoretical predictions. The major difficulty in the comparison is the lack of detailed information about the conversion of laser light into x rays, especially in the 1.3-/mu/m experiments.
