摘　　要：以某次上海市冷水水表量值比对为背景建立了比对测量的数学模型,通过贝塞尔法和极差法分别计算了传递标准的稳定性,在对参比实验室的比对结果评价后,得出了在一定的试验次数下经不同的稳定性评估方法得到的量值比对评价结果基本是一致的。这对类似的比对活动具有一定的参考价值。Based on the quantity comparison of the cold water meter values in Shanghai, a mathematical model for comparison measurement is established in this paper. The stability of the transfer standard is calculated by the Bessel Method and the Range Statistics Method respectively, and after evaluating the quantity comparison results of the comparative laboratory, it is concluded that the results of quantity comparison obtained by different stability evaluation methods under certain test times are basically the same. This article could provide reference for similar comparison activities.
