摘　　要：为了定量分析产品的合格性,在正态分布假设前提下,考虑参数测量结果测量不确定度的影响,建立了双侧公差限产品的合格概率计算模型,为批量产品和单件产品合格概率的定量计算提供了理论依据,同时给出了测量分析计算实例。结果表明:产品合格概率的定量计算结果,对于分析产品质量问题成因和提高产品质量具有重要的指导意义,给出的方法对单侧公差限设计要求的产品合格概率的计算同样具有参考价值。A calculation model of products＇ qualified probability is established to quantitatively analyze products qualification, considering the influence of uncertainty of parameter measurement and based on the assumption of normal distribution. The design requirement of products is bilateral tolerance limit. The model provides a theoretical basis for the quantitative calculation of batch products＇ and single product＇ qualified probability, and gives a calculation example of measurement and analysis. The results show that the quantitative calculation results of products＇ qualified probability has an important guiding significance for the analysis of product quality problems and improving the quality of products. The given method also has referenced value for the calculation of product qualified probability, which design requirement of products is unilateral tolerance limit.
