| Abstract: | The envelope periodic solutions to some nonlinear coupled equations are obtained by means of the Jacobielliptic function expansion method. And these envelope periodic solutions obtained by this method can degenerate tothe envelope shock wave solutions and/or the envelope solitary wave solutions. |
| Keywords: | Jacobi elliptic function nonlinear coupled equations envelope periodic solution |
