In this paper, we have considered the van der Waals equation of state to study the one-dimensional spherically symmetric self-gravitating interstellar gas clouds. The transport equation for the acceleration waves is obtained. The evolution and propagation of the characteristic shock are considered to study its interaction with the acceleration wave. The amplitudes of the reflected and the transmitted waves are also determined. The effect of non-ideal parameter on the amplitude of the acceleration waves is discussed in detail.

星际气云中加速度波与特征激波的相互作用

在本文中，我们考虑了范德华状态方程来研究一维球对称自重星际气体云。获得了加速度波的输运方程。考虑了特征冲击的演化和传播，以研究其与加速度波的相互作用。还确定了反射波和透射波的幅度。详细讨论了非理想参数对加速度波振幅的影响。
