摘要： 将基于案例的推理方法应用于智能故障诊断系统中，具体讨论了故障案例库和结果库的建立，并将其用关系数据库的格式进行存储。应用灰色关联理论和模糊集结合矢量投影学，给出了关联度的定义和计算方法，从而可以准确地检索到相似的故障案例，对待检测故障给出定性或者定量的分析。

Abstract: Case-based reasoning is applied to faulty diagnose system.The method of building faulty cases base and result base is disccussed,they are restored according to database.A method of relational degree based on grey-relational theory and vector projection is put forword.Thus, similar cases can be found out accurately.The fundation is laid for future reseach.
