1.标准样品特性标准值的测量不确定度评定和G U M的关系从理论上讲,测量不确定度仅仅是对一个具有溯源性的测量结果离散程度的描述,在《国际通用计量学基本术语》(VIM)中是这么定义的:与测量结果相联系的参数,表征合理地赋予被测量之值的分散性。因此,要合理地评定一个测量结果 1. Standard sample characteristics of the standard value of the measurement uncertainty and the relationship between the GUM In theory, the measurement uncertainty is only traceability of traceability with a description of the degree of dispersion in the “International Fundamentals of Metrology” (VIM) is defined as the parameter associated with the measurement that characterizes the dispersion that is reasonably assigned to the measured value. Therefore, a reasonable assessment of a measurement results
