摘要
本文利用微分形式的吴方法讨论了Kdv-Burgers-Kuramoto方程的古典对称及其不变解,同时得到了Burgers方程的势对称,并利用这些势对称作用到Burgers方程的解上从而得到了该方程更多的精确解.
The classical symmetries and their invariant solutions of Kdv-Burgers-Kuramoto equation are discussed with the help of Wu s method in differential forms,and potential symmetries of Burgers equation are obtained.Furthermore,more exact solutions are worked out by applying these potential symmetries to the solutions of Burgers equation.
