摘要
Two-dimensional （219） relativistic magnetosonic solitons in the negative-ion-rich plasma consisting of positive ions Ar＋, negative ions SF6 and electrons are investigated in the presence of an applied magnetic field Bo and can be described by a Kadomtse-Petviashvili （KP） equation in the weakly relativistic limit. The ratio of positive ion density to negative ion density has a marked influence on the amplitude φm and width W of the steady-state KP soliton. The interaction law of the nontrivial solitons with rich web structure is studied by the Wronskian determinant method.
