摘要根据VIM(3rd)、JJF 1001—2011和JJF 1059.1—2012,对《ISO/TR 7066-1:1997 Assessment of uncertainty in calibration and use of flow measurement devices-Part1:Linear calibration relationships》、ISO 5168:2005和GB/T 29820.1—2013,对其中的若干术语、定义和符号作了初步分析,提出了一些不同看法和修改意见;分别对ISO/TR 7066-1和ISO 5168中关于“随机误差”、“系统误差”、“标准偏差和方差”;“不确定度和不确定度评定”、“重复性测量条件”,以及“灵敏度”和“线性校准方程”等定义和注解的表述进行了讨论。
Abstract：According to the VIM(3th),JJF 1001—2011and JJF 1059.1—2012, further comments have been made, and different views and proposed changes put forward as to several terms, definitions, notes in ISO/TR7066-1(1997), ISO5168(2005) and GB/T 29820.1—2013. Detailed analysis have been made on “random error”, “systematic error”, “standard deviation and variance”, “uncertainty and evaluation of measurement uncertainty”, “repeatability conditions”, “sensitivity”, and “calibration linear equation” in all above documents.
