摘要: The problem concerning the appropriate form for nonlinear frequency shift arising from slow density modulations of electrostatic surface waves in a semi-infinite unmagnetized plasma is reconsidered. spatial dependence wave amplitude normal to kept general order allow possible attenuation behaviour waves. It found that if expressed as function and its gradient then result identical with Zhelyazkov (1987 b ), who assumed linear exponential behaviour.
