摘　　要：介绍了在收集液压系统专家知识中,采取对象分类,从代表性对象的最底层子类对象开始,依次进行知识的收集。将领域专家知识分为基本知识和原则知识,用基本知识进行表达,给专家知识添加边界条件和对专家知识的功能模拟,加快收集专家知识的速度。所收集的专家知识全面、有效,也便于知识库的组织和维护管理以及推理效率的提高。The basic procedure adopted in acquiring the knowledge of expert system is introduced for hydraulic system diagnostics. The knowledge was collected in sequence starting from the lowest sub-category objects with object classifying method. The expert knowledge domain was classified as basic knowledge and principle knowledge and was expressed by the former. Adding border conditions and function simulating to it speeded up the collection of expert knowledge. So the collection of expert knowledge was complete and effective. All these facilitated the organization and maintenance of the knowledge base and the increase of inference efficiency.
