摘要：

对容量法测定工业锅炉水总碱度进行不确定度评定。充分考虑测量重复性、标准溶液的配制、滴定等过程对测量的影响,计算水中总碱度的测量相对合成标准不确定度为3. 8×10^-3。

关键词: 总碱度, 测量不确定度, 锅炉水

Abstract:

The measurement uncertainty of the total alkalinity of water quality in industrial boilers has been evaluated by volumetric method. The effect of the influential factors， such as repetitiveness， preparation of standard solution， titration， etc on the measurement is considered sufficiently． The uncertainty of the relative synthetic standard of the measurement of total alkalinity in water is calculated as 3. 8×10^-3.

Key words: total alkalinity, measurement uncertainty, boiler water
