我们将简要描述的研究是试图阐明地球弓形激波的结构。与气体动力学冲击不同，无碰撞等离子体冲击可以以多种不同的方式耗散定向流动能量。在某些模型中，激波结构由等离子体-磁场相互作用决定（Kennel和Sagdeev，1967 a和B）;在其他情况下，相互作用被假定为主要是静电的（Tidman，1967; Tidman和Krall，1971）。在弓形激波中，实验证据（Fredricks等人，一九七○年;也参见Bertotti和Schindler 1971的评论）指出了磁和静电波动的存在，并且对于耗散过程，即使在定性的基础上，也不存在明确的图像。
The investigation which we shall briefly describe is an attempt to shed light on the structure of the earth’s bow shock wave. Unlike gas dynamic shocks col-lisionless plasma shocks can dissipate directed flow energy in a number of different ways. In some of the models the shock structure is governed by plasma-magnetic field interaction (Kennel and Sagdeev, 1967a and b); in other cases the interaction is assumed to be predominantly electrostatic (Tidman, 1967; Tidman and Krall, 1971). In the bow shock the experimental evidence (Fredricks et al., 1970; see also Bertotti and Schindler 1971 for a review) points to the presence of both magnetic and electrostatic fluctuations and no unambiguous picture exists, even on a qualitative basis, for the dissipation processes.
