摘　　要：以模糊数学理论为基础,提出了一个用于某转子系统初始弯曲故障诊断的模糊专家系统。利用隶属度和模糊综合评判的概念和方法有效地处理了领域知识描述和诊断推理中的不确定性问题。指出了在模糊推理模型中,模糊诊断权矩阵是专家诊断知识和诊断经验的集中体现,并且给出了确定的初始权矩阵的方法。This paper is about fuzzy reasoning method in expert system for one rotor fault diagnosis.The concept and the method of membership and fuzzy comprehensive judgements are used to deal with the field knowledge description and the uncertain problem in diagnosing inference.It was pointed out that the fuzzy diagnosis weight matrix in the fuzzy diagnosis model was the concentrative reflection of the diagnosis knowledge and experiences of the human experts.At last,the algorithm to originally determine diagnosis weight matrix is given.
