利用(G′/G)展开法给出(2+1)维Burgers方程和(2+1)维色散长波方程的一组(G′/G)结构的行波解.当解中参数取定某些特殊值时,将得到这两个方程的孤波解.
By using the (G'/G)-expansion proposed recently,the travelling wave solutions involving parameters of the(2+1)-dimensional Burgers equation and the(2+1)-dimensional dispersive long wave equations are found out. When the parameters are taken as special values the solitary wave solutions are obtained.
