一、测量结果溯源性的本质及ＶＩＭ关于溯源性的定义众所周知 ,从根本上讲 ,所有的溯源性都是比较 (直接比较或间接比较 )。即采用一个已知量值与一个待测对象进行直接(或间接 )的比较 ,由此获得待测对象的量值。显而易见 ,为了确保在不同的时间和空间对相同的待测对象进行测量 First, the nature of the traceability of measurement results and the VIM definition of traceability As we all know, basically all traceability is compared (direct comparison or indirect comparison). That is, using a known value and an object to be measured directly (or indirectly), thereby obtaining the value of the object under test. Obviously, to ensure that the same object to be measured is measured in different time and space
