测量不确定度的评定与表示

Evaluation and Presentation of Uncertainty in Measurement

测量不确定度如何正确评定与表示,是个极其重要的问题,通过实例介绍了不确定度的有关概念,给出了标准不确定度A类、B类评定的方法,以及标准不确定度的合成方法与展伸不确定度。

It is known to all that how to evaluate and present the uncertainty in measurement properly is a very important problem. The related concepts are to be introduced, two methods to evaluate standard uncertainty known as A type and B type are to be compared, and the combined standard uncertainty and the expanded uncertainty are to be discussed in detail in this article.
