| Abstract: | In this paper, the G＇/G-expanmon method is improved to construct travelling wave solutions of nonlinear evolution equalions with the tools of transformation and computer algebraic system Maple. In order to illustrate the effectiveness and advantages of the method, the author applies it to the Burgers-Fisher equation. Many new and general formal exact solutions are obtained including the hyperbolic function solutions and trigonometric function solutions. |
