| 摘 要： | 从一般单流体方程出发,考虑了各种可能的效应,如粘性、电导、热传导、碰撞、引力、自转等,推导出了一般情况下的色散关系。具体地讨论了在热传导条件下色散关系的特殊性质和相应的等离子体低频噪声的传播形态。用所得的分析结果说明了航天器环境扰动和其他有关的空间现象。

| Abstract: | Plasma wave dispersive relation was derived from onefluid MHD (Magnetohydrodynamic) eqautions in the region with possible effects such as viscosity, electric conductivity, heat conductivity, collision and self-rotation. The characteristics of the dispersive relation and the propagation of plasma low frequency noise are discussed in details. The disturbance in spacecraft environment and other space phenomena are explained by the analytic results. |
