摘　　要：针对航空维修行业内不同角色企业故障诊断知识、系统、资源的分散、封闭、异构等原因导致的故障知识不易共享、重用的问题,采用本体来构建故障知识库;并设计其本体知识模型结构,以表达故障现象与故障结论间存在的不确定性关系;进一步编写相应的推理规则,设计基于本体的不确定性推理系统。以飞机发动机故障诊断为例进行了验证。In view of the dispersive, closed, heterogeneous knowledge, system and resource of fault diagnosis of the aviation-repair- industry enterprises in different roles, which causes uneasy sharing and reusing problems of fault knowledge, it uses ontology to construct a fault diagnosis knowledge base. In order to express the uncertainty relation between fault phenomenon and fault conclusion, a ontology model structure is built. It designs the corresponding inference rules, and puts forward an uncertainty reasoning system based on ontology. In aircraft engine fault diagnosis the method is verified.
