| 摘 要： | 本文分析各类激波特别是中间激波的特性与上游阿尔文数、激波角和气压-磁压比的关系,阐明各类激波在上游参数空间的连接方式.主要结论是:当上游阿尔文波速大于声速时,慢激波和快激波可通过三种基本方式相互连接;当上游阿尔文波速小于声速时,激波连接只限于慢激波和中间激波之间.这些结论有助于进一步探讨混合激波的结构和演化规津.

| Abstract: | In this paper the dependence of the properties of various types of shocks, especially intermediate shocks, upon the Alfvenic number, the shock angle, and the ratio of gas pressure .o magnetic pressure upstream are discussed, and the linkage of various types of shocks in the upstream parameteric space are explained. The main conclusions are as follows. As the Alfvenic speed is larger than the sound speed upstream, a slow shock and a fast shock may link with each other through three basical ways. On the other hand, as the Alfvenic speed is less than the sound speed upstream, the shock linkage occurs only between a slow shock and an intermediate shock. These conclusions are helpful for further studying the structure and the evolution of hybrid shocks. |
