将形式变量分离方法推广应用于一个不可积的一般Hirota-Satsuma方程,得到了一些新的孤波解和周期波解.The usual formally variable separation approach is valid only for completely integrable models. In this paper, we extend the method to a nonintegrable generalized Hirota-Satsuma equations. Some new exact solitary wave solutions and periodic wave solutions of the equations are also obtained.
