摘 要: | The weak nonlinear modulation of the surface wave of a three-dimensional imcompressible fluidwithout rotation,which is contained in a rectangular trough is studied by using the method of multi-ple scales perturbation theory.The effects of viscid and external drive on the motion,which modifiesthe Larraza-Putterman equation,are considered.The results are consistent with that of Miles.
