Propagation of Nonlinear Solitary Waves in Nonuniform Dusty Plasmas with Two-Ion Temperature

摘要

The nonlinear properties of dust acoustic solitary waves in inhomogeneous dusty plasmas with two-ion temperature are investigated.By using the reductive perturbation theory,a modified variable coefficients Korteweg-de Vries(MKdV)equation is derived.The typical integral form of the Sagdeev potential is examined numerically.The numerical results show that the inhomogeneity,the two-ion temperature have strong influence on the nonlinear properties of dust acoustic solitary waves.
