中小型汽轮机径向滑动轴承设计专家系统的研究 三、TJBDES的知识表示及推理机制

The Study on the Middle or Small Type of Turbine Journal Bearing Design Expert System——Ⅲ.The Knowledge Representation and Inference Engine of TJBDES

本文着重介绍TJBDES 的知识表示方法及知识库的组成,为扩大知识库的容量,把汉字DBASE—Ⅲ数据库作为专家系统的外部知识库,成功地实现了Turbo Prolog 环境与汉字DBASE—Ⅲ数据库的接口;最后阐述了TJBDES 用户接口模块及推理机制的设计。

This paper presents mainly the Knowledge repre sentation method of TJBDES and its Knowledge base Structure,The Turbo Prolog environment is interfaced sucessfully with the Chinese DBASE-Ⅲ database which is used for external knowledge base of this expert system in order to enlarge the capacity of the knowledge base.At Last,this paper discusses how to design the user interface module and the inference engine of TJBDES.key words:expert system,knowledge representation method,knowledge base,DBASE-Ⅲ data base,inference engine
