摘要：

The present paper is concerned with a long time asymptotic behaviour of a weakly Landau-damped, monochromatic plasma wave in the collisionless electron plasma, the amplitude of which is assumed small but finite. The theory is based on an asymptotic expansion in terms of the decay constant of the Landau damping. The method of characteristics to integrate the Vlasov equation is brought into the scope of the asymptotic method. It is shown then that the slowly varying part of the amplitude Landau-damps if the decay time is much shorter than the period of the amplitude oscillation, whilst it oscillates if they become the same order. © 1969, THE PHYSICAL SOCIETY OF JAPAN.
