摘要
通过推广的F-展开法研究了变系数BBM(Benjamin,Bona and Mahony)方程的精确解,通过线性变换将变系数BBM方程约化为标准椭圆方程形式,由标准方程的行波解的结构求出原方程的解,从而得到了变系数BBM方程丰富的精确解.同时研究了解随参数的变化而变化的情况.
In this paper, the extended F-expansion is used to study the variable coefficient BBM equation. Firstly,the BBM equation is converted into a standard elliptic equation through linear transformations, and its exact solutions are obtained by the structure of standard elliptic equation's wave solution and parameter hypothesis. Simultaneously, varying situations of the solutions with parameter are also investigated.
