摘　　要：介绍了排管电阻的测量不确定度评定方法。通过分析排管电阻的测试过程,建立了电阻测量的数学模型,确定了测量不确定度的来源。采用A、B类评定方法对各因素引起的不确定度分量、合成标准不确定度和扩展不确定度进行评定,并给出评定结果。This paper introduces the measurement uncertainty evaluation method of tube resistance.Through the analysis of the experimental process of tube resistance,the mathematical model of resistance measurement is established,and the source of measurement uncertainty is determined.The uncertainty components,synthetic standard uncertainty and extended uncertainty caused by various factors were evaluated by Class A、B evaluation method,and the evaluation results were given,which has reference significance for measuring uncertainty in physicochemical analysis.
