| 根据图论中欧拉公式推得二维有限元网格图中单元数、节点数、边数及边界数之间的关系式，获得判别网格图中是否存在节点号重复和单元遗漏的简便算法。 |
| 英文摘要: |
| HT5\"SS]The relationship among number of elements, number of nodes, number of the edges on the boundary and number of close boundaries in the mesh drawing of finite element analysis is infered by a suitable variation of Euler equation. The arithmetic that can be used to judge whether there is duplicate of node numbers or lose of element numbers in the mesh drawing with it is also got. A simple method used to judge the integrity and the accuracy of a model is found. |
