摘要
在这糊，由使用符号并且代数学计算，陈和王“ smultiple Riccati 方程合理扩大方法进一步被扩大。另外的小说联合了的许多双 soliton-likeand 准确答案形成(2+1 ) 维的碎 soliton 方程被使用扩大多重 Riccati 方程扩大方法导出。
In this paper, by using symbolic and algebra computation, Chen and Wang＇s multiple R/ccati equations rational expansion method was further extended. Many double soliton-like and other novel combined forms of exact solutions of the （2＋1）-dimensional Breaking soliton equation are derived by using the extended multiple Riccatl equations expansion method.
