Abstract: 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.-
