浅识产品测量当中的不确定度

工业生产、质量检验、计量等领域，通常要经测量来检验原材料和产品是否符合技术要求；其合格与否的判定，看似简单、其实并不容易。我们在日常检测时，常常容易将误差与不确定度混淆，误差是一个确定值，而不确定度则是一个区间。只有明确了不确定度产生的原因，并掌握一定测量技巧及方法，才能更准确地表示出被测物质的真实状况。

Shallow Knowledge of Measurement Uncertainty of the Products

In industrial production, quality inspection and measurement fields, we usually have to be tested by measuring whether the raw materials and products meet the technical requirements, qualified to determine whether or not a seemingly simple, is not easy work. We are often easy to detect in routine error and uncertainty will be confused. The error is a fixed value, rather than to determine the degree is an interval. We only identify the causes of uncertainty, and have some measurement techniques and methods, so as to more accurately express the true state of the tested material.
