计量用量筒容量测量的不确定度评定

Evaluation to Uncertainty in Measurement of Capacity of Measuring Cylinders

测量不确定度是表征合理地赋予被测量之值的分散性,与测量结果相联系的参数。不确定度是国际公认的用来评定测量结果质量的参数,是报告度量的尺度。使用任何测量仪器,均应考虑其示值的不确定度,以便依据测量结果,判断测量仪器是否符合有关的技术要求。实验证明,本工作方法可以准确地获得测量结果的不确定度,具有很好的实用价值。以下操作选用0~210 g·(0.1 mg)^(-1)的电子天平PR1203作为计量标准器,以测量计量用量筒1 mL容量为例。

Uncertainty is the parameter that attribute the dispersity of measured value and tied with the determinate value.Uncertainty is an internationally recognized quality measurement used to assess the parameters,is to report the scale of measurement.You should take its measurement uncertainty about indication into account,when using any measuring instruments,so that you can determine whether the measuring instruments meet the relevant technical requirements or not according to measurement results.The experiment proved that the approach in this paper can acquire the uncertainty of measurement results accurately,it had best practical value.The following operation selected(0210)g·(0.1 mg)-1 electronic scales as measurement standard instruments.This article is trying to measure the capacity of 1mL.
