不确定度在检测试验室的应用
The application of measurement uncertainty in testing Lab.
摘要 本文介绍和探讨了检测试验室在受到资源和时间的限制而不可能进行重复测量和求出A类不确定度的情况时,如何在单次测量条件下利用已知条件进行不确定度的估计,并结合电气试验室最经常遇到的温度测量和电压测量给出不确定度分析和计算实例;本文介绍了进行检测和校准结果判定时如何考虑不确定度。

Abstract The paper discussed and introduced how to estimate the uncertainty from
single observation in case of estimation of the type A measurement uncertainty from
repeated observations is impracticable in Testing Lab., due to the limitation of time
and resources,this paper also gives 2 examples related to temperature measuring and
current measuring. The end of the paper introduced the judgement in consideration of
uncertainty, of the results of testing and calibration.
Keywords the evaluation of uncertainty, single observation, repeated observation,
