从理论上研究了各向同性可压缩多流体等离子体中的相互作用关系。电流源和电磁场的互易定理，这是经常采用的自由空间中发现，保证在这样的介质。互易性被证明是有效的情况下，天线是由一个突然的真空鞘包围下的物理允许的边界条件。在不发生碰撞的条件下，建立了波扰动粒子的电荷源和数密度的倒易定理。它还表明，类似的互易关系成立的准静态近似没有任何限制。最后，作为互易定理的应用，获得了给出对于诸如电子等离子体波和离子声波的入射静电波的天线接收电压的一般表达式。
Reciprocity relations in an isotropic compressible multifluid plasma with collisions are theoretically investigated. The reciprocity theorem for current sources and electromagnetic fields which is often employed for a free space is found to be guaranteed in such a medium. The reciprocity is shown to be valid also for the case that an antenna is surrounded by an abrupt vacuum sheath under a physically permissible boundary condition. Furthermore, the reciprocity theorem is established for electric charge sources and number density of wave perturbed particles under the condition that there is no collisions among perturbed particles of different species. It is also shown that the similar reciprocity relation holds for the quasistatic approximation without any restrictions. Finally, as an application of the reciprocity theorem, a general expression giving antenna receiving voltages for incident electrostatic waves such as an electron plasma wave and an ion acoustic wave are obtained.
