We simulate numerically the gravitational collapse of a gaseous polytrope and the following formation and propagation of a shock,using a high resolution scheme in computational fluid dynamics called PPM(The Piecewise Parabolic Method).
本文采用计算流体力学中的高分辨率ＰＰＭ格式，数值模拟了多方气体球的引力坍缩、激波形成和传播，物态方程取成Ｐ＝Ｋ（ｓ）ργ，γ为密度的分段函数，通过绝热指数γ的不同取法对三个模型分别进行了计算，并对引力坍缩、反弹激波形成和传播等三个过程以及不同模型之间计算结果上的一些差异做了比较仔细的分析，得到了一些初步结论。
As to the fourth strength theorem,there is still inadequate on application,so this paper at first starts from the theorem of molecular attraction and repulsion,then combining some experimental facts to revise the fourth strength theorem in order to make it more applicable.
