磁流体中间激波的相互作用

INTERACTION BETWEEN MHD INTERMEDIATE SHOCKS

本文讨论磁流体中间激波的相互作用规律．主要结论：中间激波汇合的产物为后向快简单波、后向慢简单波或慢激波、接触间断、前向慢激波和前向快激波，其中后向波成份和接触间断很弱．当左（右）激波较强时，中国激波碰撞产物为后（前）向快激波、后（前）向慢简单波或慢激波、负（正）切向间断、前（后）向慢简单波和前（后）向快激波．

This paper discusses the interaction between MHD intermediate shocks. The main conclusions are as follows. The outcome of MHD intermediate shock merging consists of a reverse fast simple wave,a reverse slow simple wave or shock,a contact surface,a forward slow shock, and a forward fast shock, in which the reverse waves and the contact surface very weak.The outcome of MHD intermediate shock collision depends on the relative strength of the left and right shocks before collision. When the left shock is stronger,the outcome consists of a reverse fast shock,a reverse slow simple wave or shock,a negative contact surface,a forward slow simple wave, and a forward fast shock. On the contrary, the outcome becomes a reverse fast shock, a reverse slow simple wave, a positive contact surface,a forward slow simple wave or shock, and a forward fast shock.
