中文摘要：
利用文献中引入的变换，将非线性偏微分方程化为非线性常微分方程，再直接求解该常微分方程，从而简洁地求得了KdV方程和KdV-Burgers方程的若干显式精确解析解，包括孤波解、奇异行波解等．
英文摘要：
By using a transformation introduced formerly,a nonlinear partial differential equation was reduced to a nonlinear ordinary differential equation, and then solved directly. A series of explicit and exact analytical solutions to the KdV equation and KdV-Burgers equation, including solitary wave solutions and singular travelling wave solutions etc. ,were derived easily.
