| 摘 要： | By considering the vortex-like ion distribution,we know that the nonlinear dust acoustic wave can be described by the modified Korteweg-de Vries equation.If there are high-order transverse perturbations in this system,the governing equation for this system is the modified Kadomtsev-Petviashvili equation.We also find that for this system under the transverse perturbation the one-dimensional solitary wave solution is stable.
