【摘要】 关于非线性发展方程的孤波解问题一直是人们感兴趣的一个研究课题 .本文指出文 [2 ]中关于Kundu方程和导数 Schr dinga方程的结论事实上是可以用积分法得到 ,而且文 [1 ,2 ]中涉及到的其它非线性发展方程的相应结论 ,用积分法也能得到更多还原

【Abstract】 Studying explicit exacdt solutions of nonlinear evolution equations is a vastly open research field. In this paper, we show that the results of Paper \ actually can be obtained by the method of elementary calculus analytics, and this method is also available for some other nonlinear evolution equations investigated in Paper \.更多还原
