本文研究了非磁化碰撞尘埃等离子体中的离子-尘埃流动不稳定性，其频率ω小于尘埃碰撞频率νd。在某些条件下，即使尘埃声波受到很大的抑制，离子热速度量级的离子漂移也可以激发出阻性不稳定性。文中还考虑了弱碰撞对ω>；νd区常见尘埃声学不稳定性的影响。在实验室直流低频起伏实验观测中的应用。讨论了辉光放电尘埃等离子体。
This note investigates an ion-dust streaming instability with frequency ω less than the dust collision frequency νd, in an unmagnetized collisional dusty plasma. Under certain conditions, a resistive instability can be excited by an ion drift on the order of the ion thermal speed, even when the dust acoustic wave is heavily damped. The effect of weak collisions on the usual dust acoustic instability in the regime ω > νd is also considered. Applications to experimental observations of low-frequency fluctuations in laboratory d.c. glow discharge dusty plasmas are discussed.
