| Other Abstract | In this paper,the governing equation for the propagation of nonlinear acoustic waves inthe magnetized plasma of solar wind is derived from the MHD system. By the numerical inte-gration technique,the analytical solutions for the perturbed electric potential and hence thefluctuation of ion density are obtained. Then the exact solutions are used to give a reasonableas we1l as probab1e explanation for the formation of nonlinear acoustic waves propagating inthe magnetized plasma of solar wind,with the help of the observation results by Satellites .The results shows that acoustic waves traveling in the solar wind propagate perpendicular to the direction of solar wind and can he very complex .may have different phase velocities and generate multi一solitons depending on the size of solar wind velocity. Meanwhile the wave width and amplitude change greatly with the propagation directions and solar wind velocity. |
