摘要
In this work, we established exact solutions for the combined KdV-MKdV equation. By constructing four new types of Jacobi elliptic functions solutions, the Jacobi elliptic functions expansion method will be extend. With the aid of symbolic computation system mathematica, obtain some new exact periodic solutions of nonlinear combined KdV-MKdV equation, and these solutions are degenerated to solitary wave solutions and triangle function solutions in the limit case when the modulus of the Jacobi elliptic functions m &rarr 1 or m &rarr 0.
