求二维DKdV方程精确解的方法

The exact soliton wave solution for the two-dimensional Korteweg-de Vires-Burgers equation is obtaind via introducing nonlinear transformations.This method,which is different from reference[1],here is very concise and primary.The metheod in this letter can be applied to other nonlinear equations.

一类dKdV方程的行波解分支

应用动力系统分支理论研究一类dKdV方程。给出了该方程在不同参数下对应行波系统的相图,根据相图求出周期尖波解和孤立波解的精确参数表达式,通过Maple进行数值模拟计算,绘制了2种参数下的周期尖波解和孤立尖波解的图像。
