With the aid of symbolic computation system Maple, several new kinds of generalized exact solutions for the compound KdV system and extended KdV-Burgers system with nonlinear terms of any order are obtained by using a new generalize Riccati equation rational expansion method. This approach can also be applied to other nonlinear evolution equations with nonlinear terms of any order.
