摘要 利用推广的(G′/G)展开法,借助于计算机代数系统Mathematica,获得了(2+1)维BBM方程的丰富的显式行波解,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,abundant exact travelling wave solutions of the (2+ 1)dimension BBM equation are successfully obtained.The solutions are expressed by hyperbolic functions, trigonometric functions and rational functions contained double arbitrary parameters.
