仔细研读了刊登在《中国计量》杂志2012年第1期的《可燃气体检测报警器示值测量结果不确定度评定》(以下简称“原文”)一文,觉得有几个地方值得商榷。一、原文在“输入量的不确定度评定”中这样表述:标准不确定度u(C)=0.42/10~(1/2)=0.13%LEL。依据《一级注册计量师基础知识及专业实务》第213页“在测量结果的不确定度评定中,当测量结果由单次测量得到时,sr(y)直接就是由重复性引入的标准不确定度分量。当测量结果由n次重复测量的平均值得到时,由重
I carefully read the article entitled ”Evaluation of the Uncertainty of Measurement Results of Indication of Combustible Gas Detection Alarm“ (”“) in the first issue of China Metrology in 2012, and I think there are a few places that are worth discussing. First, the original text in the ”input uncertainty “ in the expression: standard uncertainty u (C) = 0.42 / 10 ~ (1/2) = 0.13% LEL. According to ”The basic knowledge and professional practice of a registered metrologist“ p. 213 ”sr (y) is directly introduced by repeatability when the measurement results are obtained from a single measurement in the evaluation of the uncertainty of the measurement results Uncertainty component. The weight is given when the measurement result is obtained from the average of n repeated measurements
