扩展了Hirota法以构造(2+1)维广义浅水波方程的新的孤波解,即将Hirota法中的测试函数用新的测试函数来替代,得到了(2+1)维广义浅水波方程的周期孤立波解。显然扩展的Hirota方法也可以解其它类型的非线性演化方程。
擴展瞭Hirota法以構造(2+1)維廣義淺水波方程的新的孤波解,即將Hirota法中的測試函數用新的測試函數來替代,得到瞭(2+1)維廣義淺水波方程的週期孤立波解。顯然擴展的Hirota方法也可以解其它類型的非線性縯化方程。

Hirota method proposed recently is extended to construct more exact solutions of nonlinear evolution equations. To be more precise,new text function is used instead of text function in Hirota method. By using the extended Hirota method,(2+1)-dimensional generalization of shallow water wave equation is solved periodic soliton wave solutions. Obviously,the extended Hirota method can be applied to solve other type of nonlinear evolution equations as well.
