Abstract

The propagation of two strong radiative shocks moving opposite in an inhomogeneous cosmic medium is calculated by a 'modified' characteristic method. It is found that the shock propagation is seriously affected by radiation losses and by the inhomogeneity of the medium; the cooled and recombined post-shock gas first appears near the shock front. This differs from results derived from steady state solutions, which predict that the condensation should appear first at the contact surface.
辐射激波在非均匀宇宙介质中的传播
用一种“改进的”特征方法计算了在非均匀宇宙介质中反向运动的两个强辐射激波的传播。研究发现,辐射损失和介质的不均匀性对激波传播有严重影响;冷却和重组后的激波气体首先出现在激波前缘附近。这与稳态溶液的结果不同,稳态溶液预测冷凝应首先出现在接触面。
