摘要
探讨了利用双线性导数法求Boussinesq方程孤子解的新方法.首先通过非线性函数变换,给出4阶Boussinesq方程的双线性导数形式,然后利用待定系数法求出了方程的孤子解.此方法可用于研究一大类非线性发展方程.
We consider to solve soliton solution of Boussinesq equation by using bilinear derivative method. Fristly, the four-ordered bilinear derivative form of Boussinesq equation is given by a nonlinear function trans- formation. Then, the soliton solution of the Boussinesq equation is given using method of undetermined coefficients and the truncated technique. The method can be generalized to the study of a class of nonlinear evolution equations.
