　　Abstract: 

　　In this talk, I will show two numerical results of the mKdV-sin Gordon equation. One is the numerical calculation of the 3-periodic wave solutions. The method we used is based on the direct method of Nakamura. The other is a numerical simulation method based on an integrable dierence analogue of the equation. We give an integrable discretization of the mKdV-sine Gordon equation and design an efficient numerical method.
