摘要
本文对广义KDV-Burgers方程把方程系数看作自变量的势对称进行了讨论.借助吴-微分特征列算法程序包,我们给出了该方程8种不同类型的势对称分类.该结论说明了在我们讨论的情况下能够扩充方程的古典对称.
In this paper, a discussion is held on a new situation in which coefficients of KDV - Burgers e- quation are considered as independent variables. By using Wuwen -tsun Differential Characteristic Algorithm, the classification of 8 different types of potential symmetry is given. Results show that the classical symmetry of equation can be extended in the situation presented in this paper.
