摘要
结合截断Painlev啨展式和Painlev啨 -B cklund方程组的不同的解 ,构造了KdV方程和混合KdV -Burgers方程的显式精确行波解 ,并给出这两个方程的自B cklund变换 .
Explicit exact travelling wave solutions to the KdV equation and the compound KdV-Burgers equation are obtained by combining the truncated Painlevé expansion and the different solutions of the Painlevé-Bcklund equations.The auto-Bcklund transformations for this two equations are also presented.This method also can be applied to construct the exact travelling wave solutions to other nonlinear evolution equations.
