摘      要：Nonlinear interaction of the Langmuir wave and the dust-acoustic wave in plasmas with the variable-charge grains has been *** the approximation of small amplitude,we find the solution of envelope soliton for the nonlinear Langmuir *** results show that the amplitude of envelope soliton increases with the increasing of dust grain density.
