摘要 利用扩展的(G'/G)-展开法,借助于计算机代数系统Mathematica,获得了gZK方程和ZK方程3种类型的显式行波解,分别以含两个任意参数的双曲函数、三角函数及有理函数表示. By using the extended(G'/G)-expansion method and with the aid of computer algebra system Mathematica,three types of exact travelling wave solutions to the gZK equation and ZK equation are obtained.The solutions are expressed by hyperbolic functions,trigonometric functions and rational functions with double arbitrary parameters,respectively.
