利用(G'/G)展开法求得了著名的Mikhailov-Shabat-Sokolov(MSS)方程的双曲函数解、三角函数解和有理函数解3种形式精确行波解;特别地,当参数取特殊值时,双曲函数解可以转化成孤立波解.%The exact travelling wave solutions of the famous Mikhailov-Shabat-Sokolov (MSS) equation,which contained three kinds of forms,such as the solution of hyperbolic functions,the solution of trigonometric functions and the solution of rational functions,were obtained by using the (G'/G) expansion method.Especially when the parameters were taken as special values,the solution of the hyperbolic functions could be transformed into the soliton wave solutions.
