摘    要:研究了尘埃等离子体中尘埃声波(DAW)和尘埃离子声波(DIAW)对朗缪尔波的非线性调制。在小而有限振幅极限下,得到了朗缪尔波的包络孤立子。对于朗缪尔波与尘埃声波的非线性耦合,包络孤立子存在两个速度传播区;而对于与尘埃离子声波的耦合,只有一个传播区

关 键 词:尘埃等离子体  尘埃声波  朗缪尔波  非线性调制

Abstract:The nonlinear modulation of the Langmuir waves by the dust acoustic waves (DAWs) and the dust ionacoustic waves(DIAWs) has been investigated. The analytical solutions of envelope soliton have been found in the limit of small amplitude. For the coupling between the Langmuir waves and the DAWs, there are two regions of envelope soliton propagation, the gully between which becomes narrower with the increasing of the dust number density. And there is only one region of propagation speed for the coupling with the DIAWs.
Keywords:Dusty  plasma  DAW    DIAW  Langmuir  envelop  soliton
