An exponential function method was proposed for obtaining the exact solutions of KdV-Burgers-Kuramoto equation,and exact solutions of exponential function type of Kuramoto-Sivashinsky equation were also provided.Exponential form solutions by hyperbolic function transformation can be transformed into hyperbolic function solutions.Corresponding graphs of the two kinds of non-linear system solutions were presented and it can be seen their solutions are solitary wave solutions and kink solutions.
