行星际中间激波

INTERPLANETARY INTERMEDIATE SHOCK

在行星际空间可能存在由各类激波连接而成的混合激波,其组成部分的连接方式和时间演化遵循“慢激波—导灭激波—中间激波—导生激波—快激波”链式规则.中间激波将作为混合激波的必要组成部分,出现在日球电流片的附近,其阵面凹向太阳.上述结论已初步为观测证实,并对行星际激波的三维特性有着重要影响.

A hybrid shock formed by linking up different types of shocks may exist in the interplanetary sparce, and the linkage and the evolution of its components observe the chain rule of 'slow shock-switch-off shock-intermediate shock-switch-on shock-fast shock'. As a necessary component of a hybrid shock, the intermediate shock occurs in the vicinity of the heliospheric electric current sheet with its front concave towards the sun. This conclusion is confirmed by observations to a certain extent, and has important relations with the 3-dimen-sional properties of interplanetary shocks.
