Elliptic equation is taken as an ansatz and applied to solve nonlinear wave equations directly.More kindsof solutions are directly obtained,such as rational solutions,solitary wave solutions,periodic wave solutions and so on.It is shown that this method is more powerful in giving more kinds of solutions,so it can be taken as a generalizedmethod.
