摘要
本文利用改进的Tanh函数展开法,并借助于符号计算软件Mathematica,求解了变系数Benjamin-Bona-Mahony-Burgers(BBMB)方程,获得了该方程丰富的精确解,其中包括类孤子解、有理函数解和三角函数解.
In this paper,the variable coefficient Benjamin-Bona-Mahony-Burgers(BBMB)equation is solved by using the improved Tanh function expansion method and the symbolic computation software Mathematica,and a variety of exact solutions are obtained,including the soliton-like solution,the rational function solution and the trigonometric function solution.
