摘要

Stability of a dust acoustic wave in cylindrical complex plasmas is investigated.Effects of a static magnetic field (axial) and an electric field (radial) on the propagation of a low frequency wave are studied.The linear dispersion relations of rotational modes and breathing modes are derived.When a dusty plasma is confined in a finite region,the void behavior is observed at high speed rotation.Vivid structures of different-mode-number solutions are illustrated.
