摘要：

A method is outlined to derive Sagdeev's pseudopotential which can take into account the dusty charge fluctuation. Numerical solutions of Sagdeev's master equations are obtained to show the existence of solitary waves. Also, for small amplitude, explicit analytical expressions for solitary waves and double layers are obtained. (C) 2002 American Institute of Physics.
