| 作者姓名： | 许学谘 陈怀永 |
| 摘 要： | In this paper,including some partial differential equations with a number ofindependent variables,which can be reduced by the.infinitesimal form of the group,weobtain the theory of similarity transformation and its application of the second ordernonlinear partial differential equations which have two independent variables and twodependent variables in mechanics. |
