累计料斗秤测量结果的不确定度分析与评定

Uncertainty analysis and evaluation of the cumulative hopper scale measurement

本文主要介绍了在累计料斗秤试验过程中不确定度的来源,并以物料试验为例,重点介绍了计算各分量的标准不确定度、合成标准不确定度以及扩展不确定度的方法。

this paper mainly introduces the source of uncertainty in cumulative hopper scale testing process, and taking the material test as an example, introduces the standard calculation of the components in the uncertain degree, synthetic standard uncertainty and the expanded uncertainty.
