摘　　要：获得一种具有广泛的知识表示方法和灵活高效的推理逻辑是专家系统研究中一直追求的一个目标。将日益发展成熟的关系数据库技术引入专家系统,论述了一种基于关系数据库的知识表示方法和推理逻辑,利用关系数据库几乎不受限制的字段个数和丰富的字段类型来表示专家知识和组织推理逻辑,达到了知识表示的广泛性和逻辑推理的高效性。这一方法可广泛应用于各领域的专家系统,在中医专家系统的实例中,取得了令人满意的效果。To obtain an extensive knowledge representation and flexible high-efficient reasoning method is a long-range goal in the research of the expert system.A method of knowledge representation and reasoning based on relation database is discussed. This method introduces the technology of relation database which is developing rapidly into expert system, and utilizes hardly unrestricted field count and abundant field type of relation database to express expert knowledge and organize reasoning logic. The goal of extensive representation and high-efficient reasoning is achieved. This method can be applied to expert systems of every field extensively. In the application instance of the expert system to traditional Chinese medicine, the satisfactory result is obtained.
