本文将约化微扰方法应用于控制无碰撞等离子体一维运动的Vlasov方程。本公式使得研究具有任意色散的等离子体波的非线性调制成为可能。所产生的非线性薛定谔方程的结构已明确研究的电子等离子体波和离子等离子体波。
The reductive perturbation method is applied to the Vlasov equation which governs the one dimensional motion of collisionless plasmas. The present formulation makes it possible to investigate the nonlinear modulation of the plasma waves with an arbitrary dispersion. Structures of the resulting nonlinear Schrodinger equation have been studied explicitly for the electron plasma wave and for the ion plasma wave.
