摘要：

A model of gas-dynamical flow during gravitational collapse is analyzed mathematically by assuming its spherical symmetry and self-similarity. A shock wave diverging from the center emerges in this model. The physical requirements imposed on the post-shock Row at the center for the specified parameters at infinity unambiguously determine the shock front and the flow behind it.
