| 摘 要： | 运用宏代换技术实现代数式的数据化，设计镜像数组实现代数式中变量的数据库定位，从而虚拟了代数式数据类型，该数据类型具有动态性，使知识表示的粒度细化到了数据层面，由此，设计了基于关系数据库的完全数据化的知识库，系统具有更高的智能化水平。

| Abstract: | In ordcr to creating dynamic data type of relation database, the algebraic expression was digitized with macro substitution, and the mirror array was designed to locate the variables of algebraic expression in database. In this way, the virtual data type of algebraic expression was constructed in relation database, and which was dynamic. It is realized to express knowledge with data based on this kind of data type. So the knowledge base, which is digitized completely, has been designed. Because of the dynamic data type, the system intelligence is enhanced. |
