摘　　要：针对区分矩阵的特点,给出了一种求决策表的属性约简和属性核的方法,以制冷系统的故障为对象,对制冷系统的故障诊断特征参数的属性进行约简,剔除其中不必要的属性,降低了故障分析的复杂性,并根据约简后的决策表得出了决策规则。Based on fault diagnosis of refrigerated system, this paper introduces an approach for processing knowledge reduction and core by discernibility matrix. Discernibility matrix is taken as a major tool to reduce the rules of fault diagnosis system in which unnecessary properties are eliminated. The complexity of fault diagnosis systems structure is also reduced. The decision - making rules are given finally.
