摘要： The nonlinear effects of large amplitude ion acoustic wave are studied theoretically and experimentally, so as to obtain the amplitude threshold for producing the nonlinear effects, the half width of the trapped region and the transitional region width caused by collisions. The experimental results are in good agreement with the theoretical predictions.
