对影响无损检测可靠性的主要因素用模糊综合评判方法进行综合评判 ,并确定了无损检测模糊区上下限的值。在无损检测可靠度和缺陷检出概率的模糊定义基础上 ,将模糊集理论与概率统计方法相结合 ,对检测模糊可靠度和缺陷模糊检出概率进行分析计算 The main factors influencing the reliability of non-destructive testing are comprehensively evaluated by the fuzzy comprehensive evaluation method, and the upper and lower limits of the non-destructive testing fuzzy area are determined. Based on the fuzzy definition of the reliability of nondestructive testing and the detection probability of defects, the fuzzy set theory is combined with the method of probability statistics to analyze and calculate the fuzzy reliability of detection and the fuzzy detection probability of defects
