论文摘要
我们研究了与重颗粒相关的低频波模式及其在带有漂移离子的碰撞复合物等血浆中的不稳定性。讨论了离子漂移对此模式的声速的影响。考虑到粒子成分的强耦合，不稳定性的一般条件是用于亚热离子漂移的。一般趋势，强耦合效应降低了声速并促进离子漂移不稳定性的发生。从弱碰撞到粒子成分的强碰撞到强碰撞状态的广泛参数范围。选定的等离子体参数代表了PK-4实验，目前在国际空间站上运行。
We investigate the low-frequency wave mode associated with heavy particles and its instability in a collisional complex plasma with drifting ions. The effect of the ion drift on the sound velocity of this mode is discussed. The general condition of the instability is derived for subthermal ion drifts, taking into account strong coupling of the particle component. As a general tendency, strong coupling effects reduce the sound velocity and facilitate the occurrence of the ion drift instability. A wide parameter range is considered from the weakly collisional to strongly collisional regimes for the ion and particle components. The chosen plasma parameters are representative to the PK-4 experiment, currently operational on board the International Space Station.
