摘　　要：根据测量不确定度的评估与表示理论,主要从示值重复性测量、试样工作面积和试样厚度测量、拉力机引入以及计算时数字修约等方面分析了拉开法附着力测量不确定度的来源,以及测量不确定度在试验结果中的表示方法,推算了环氧聚氨酯防腐涂层拉开法附着力测量的不确定度,得出了环氧聚氨酯防腐涂层拉开法附着力测量结果的合成不确定度。According to measurement uncertainty evaluation and representing theory,the sources of uncertainty by pull-off adhesion and representing method of uncertainty in test results were analyzed from several aspects such as the repeatability measurement of indication,sample size and thickness measurement,introduction of tensile machine and digital modification during computation.The uncertainty of epoxy polyurethane anticorrosive coating by pull-off adhesion measurement was calculated,and the synthetic uncertainty of epoxy polyurethane anticorrosive coating by pull-off adhesion measurement results was obtained.
