摘要: In this paper, a damped nonlinear Schr?dinger equation governing dust acoustic solitary waves is obtained in collisional dusty plasmas being comprised of grains with charge variation, Boltzmann distributed electrons and nonthermally ions. The modulation instability (MI) dust-acoustic studied the expression MI growth rate given. numerical results show that nonthermal ions, collision effect ion-to-electron temperature ratio have strong influence on existential region different types similaritons amplitude similaritons. Furthermore, interactions two are investigated.
