Abstract
Propagation of solitons is investigated on an inhomogeneous plasmas that co ntain two kinds of ions with different masses. The nonlinear acoustic waves can be described by either KdV-type equation or Nonlinear Schrodinger equa tion in the lowest order. The amplitudes, propagating velocities or wave sh apes of these quasi-solitons are analytically given in this paper.
