摘要： 在对比和总结国内外开发的公式编辑器的基础上，提出了基于动态作图的图形符号编辑系统的形式化模型。依据该模型，对动态作图的基本原理进行了分析，并给出了动态作图的面向对象设计，实现了一个通用的编辑器系统。最后对开发中遇到的问题和难点展开讨论，并介绍了为到达系统的通用性而考虑采用的组件对象技术。

Abstract: In order to meet the needs of symbol editing in expert system, a formalized model of graphic symbol based on dynamic drawing is presented. According to this model, the analysis for the basic principle and the object-oriented design of dynamic drawing is explored. In the universal graphic symbol editing system the module technology is also adopted and some details are illustrated.
