摘要
The instability of low-frequency longitudinal modes in strongly coupled dusty plasmas with an ion flow is investigated.The dust charging relaxation is taken into account.It is found that when the ion flow is strong enough,the suppression,even disappearence,of instability can occur.Similar to that of the real frequency of waves,the imaginary part of waves also exhibits a transition,which arises from the sensitive dependences on the system parameters and their competition.
