摘要
依据图论的方法对有限元网格图进行了拓朴分析，讨论了单元节点间的相关性，提出了构造单元网格节点拓扑阵和组集整体网格节点拓扑阵的方法。这是一种新的有限元网格图自动生成方法，简洁明快，具有良好的通用性。
On the basis of the graph theoretical method, Topological analysis of the finite element mesh graph is presented. The relativities between elements and nodes are discussed. The methods for building element node topology matrix and automatic assembling the whole node topology matrix are described. This is a new method for automatic generating finite element mesh graphs. It appears succinct and versatile.
