摘要
改进 tanh 功能方法[Commun。Theor。Phys。(中国北京) 43 (2005 ) 585 ] 被概括考虑方程的 ansatz 答案进一步改进。Asits 申请，(2+1 ) 维的 Broer-Kaup 方程被考虑，丰富的新旅行 exactnon 波浪解决方案被获得。
The improved tanh function method [Commun. Theor. Phys. （Beijing, China） 43 （2005） 585] is further improved by generalizing the ansatz solution of the considered equation. As its application, the （2＋1）-dimensional Broer-Kaup equations are considered and abundant new exact non-travelling wave solutions are obtained.
