The application of Mathematical software

This paper puts the method of Jacobi elliptic function expansion into practice to solve such equations with self-consistent source in Physics, and takes a specific KdV equation with self-consistent source as an example. By means of Mathematical software, it concludes the dual-cycle exact solutions of Jacobi elliptic function, while the mold m limit to 1, these solutions will degenerate into the corresponding solitary wave solutions.
