物理实验中的不确定度评定

Uncertainty Evaluation in Physical Experiments

阐述了不确定度的定义、来源、分类及用不确定度评定测量结果的一些表示方法。分析了误差和不确定度的区别。最终给出了测量不确定度的评定。

In this paper,the relevant concepts and sources of uncertainty,and the method to evaluate the uncertainty of measurement are introduced.The difference between measurement error and uncertainty is also defined.In the end,the whole evaluation of uncertainty in measurement is given.
