Obtaining general soliton solutions of nonlinear Boussinesq equations by trigonometric function method
用三角函数法获得非线性Boussinesq方程的广义孤子解

A suitable transformation (trigonometric function method) is found to change nonlinear Boussinesq differential equations into nonlinear algebra equations, which are solved by Wu elimination method and therewith the general soliton solutions of Boussinesq differential equations are obtained.
