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