| Abstract: | In the geophysical fluid, a lot of models can be transformed into a kind of nonlinear system. In this paper, conditions for the esistence of the periodic and solitary solutions in the nonlinear system are obtained based on the Hamilton's function and generic energy method. Finally, approximate solutions are discussed. |
