| 摘 要： | 本文对流量标准装置比对试验中目前普遍使用的尤登分析法(YOUDEN ANALYSIS)进行了详细的讨论,并在此基础上,根据概率论与误差理论,提出了一种基于t分布计算尤登圆半径的新方法.运用该新方法所得到的比对试验分析结果可望更加准确可靠.

| Abstract: | The Youden analysis which is now commonly used in the intercomparison between flowmeter calibration facilities is discussed in this paper. According to the theory of probability and theory of errors, an improved statistical analysis method based on the t-distribution, which can be used to calculate the radius of the Youden circle, is presented by the authors. It is expected that the statistically analytical results of the laboratory intercomparison by use of the improved method would be more accurate, and reliable. |
