表达式图样表示法的研究及计算机实现

Research and Computer Implementation of the Expressions Representation Method of Drawings

根据图形参数化技术和图形构造规则，对表达式图样表示法进行了研究，确定了图形表达式的结构和一般内容，建立了标准化图元和标准化子图分类表以及编辑符号分类表，并且在计算机上进行了实现。

According to the parameterization technology and construction principles of graphs, the expression representation method of drawings is studied in this paper. The construction and essentials of the graph expressions are defined. The classified lists of standardized graph elements and standardized sub-graphs and editing symbols are built. And the graph diaplay of sample is achieved on computer.
