我理解为“被测量之量本身具有真值”(只是很难测量到)
= = = = = =
“被测量之值”原文是不是Measurand?Measurand 之定义为 quantity intended to be measured 应译成“被测量之量”;名词, 如铁棒的长度、水的体积等。
去测量这个Measurand后, 会得到量值(quantity value or measured value, 或称示值indicated value, 一般是数字+单位组成)。
当量值足够准确时, 可视之为约定真值。
= = = = = =
量与量值是两个不同的概念。 BIPM的 JCGM 104:2009 (Evaluation of measurement data — An introduction to the “Guide to the expression of uncertainty in measurement” and related documents) 中也有特别提到对“误差”作为量与量值的分别:
Introduction
In future editions of JCGM 200 (VIM) it is intended to make a clear distinction between the use of the term error as a quantity and as a quantity value. The same statement applies to the termindication. In the current document such a distinction is made.JCGM 200:2008 does not distinguish explicitly between these uses.
= = = = = =
我的结论:被测量之量本身具有真值, 但测量这个量而得出的量值具有分散性。
