【Abstract】 Revolving around the solution to a Riccati equation,by means of a Modified（G′/G）-expansion method,a nonlinear wave equation was constructed,namely the new exact traveling wave soltuions for the（2+1）-dimensional KunduMukherjee-Naskar（KMN）equation,for instance q_3.1,q_3.2,q_4.1 and q_4.2.With the help of Maple,the graph of the partial solution is worked out,which is helpful for the better understanding of the physical meaning of the KMN equation.更多还原
