摘　　要：将数据库技术融入到专家系统的开发中,提出了基于数据库的框架知识表示方法和基于数据库结构的埋弧焊知识库建立方法,开发了面向埋弧焊特定需求的专家系统,详细介绍了该埋弧焊专家系统的知识获取、知识库管理、咨询与推理原理及实现.系统运行表明,由于该专家系统引入了数据库技术,实现了知识与推理机制的统一,较好地解决了知识库的关键问题——维护与管理,便于系统的完善与升级,系统具有操作方便、功能实用、界面友好等特点.By introducing the database technology in the development of the expert system, this paper proposes a database-based representation method of framework knowledge and an establishment method of knowledge base for the submerged are welding. Afterwards, an expert system meeting the requirements of submerged arc welding is successfully developed. The key technologies of the expert system, such as the knowledge acquirement, the knowledge base management, the consultation and reasoning principle and the system realization, are also discussed in detail. Operation results of the expert system indicate that, owing to the adopted database technology, the unification of knowledge and reasoning mechanism is realized, and the key problems, namely the maintenance and management of the knowledge base, are successfully solved. Thus, the proposed system is easy to perfect, update and operate and is interface-friendly with versatile functions.
