摘　　要：为了通过增加测量点、从候选诊断空间中找出真正的故障元件集,深入研究了测量点的选择优化问题,通过逻辑推理与验证的方法,分析了候选诊断空间大小随新测量点的单调性变化的关系,并给出了可以导致候选诊断空间单调递增或单调递减的测量点特征。同时证明了增加相关测量点可导致诊断空间单调递减,为进一步选择优化的测量点提供了基本理论依据。To find the real fault component set in the candidate diagnostic space by gradually adding new more meas urement points, the optimization problem of choosing suitable measurement points was studied deeply, and the monotonicity of the candidate diagnostic space＇s size on the new measurement point was analyzed. The characteris tics of measurement points which could lead to monotonic increasing or monotonic decreasing of candidate diagnoses space was given. It provided a basic theoretical foundation for the optimization of practical measurement point selec tion.
