带阻尼项的坏的Bq方程的精确解

摘要

The standard tanh method and the extended tanh method were studied to solve nonlinear evolution equa-tion.The standard tanh method and symbolic computation system Maple were applied to obtain abundant exact hy-perbolic function solutions of bad Boussinesq equation with damping term,and the extended tanh method and sym-bolic computation system Maple were used to obtain abundant exact traveling wave solutions of bad Boussinesq e-quation with damping term.%研究求解非线性演化方程的tanh与扩展tanh函数法。使用符号计算软件maple和tanh函数法获得带阻尼项的坏的Bq方程的大量双曲函数精确解，使用符号计算软件maple和扩张tanh函数法获得带阻尼项的坏的Bq方程的大量行波精确解。
