摘要
利用Ｈａｍｉｌｔｏｎ函数与总能量变化方法求得地球流体中，许多模式可化成为的一类非线性系统（或其退化形式）存在周期解与孤立波解的条件，文加还讨论了周期与孤立解的近似解．
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.
