测量不确定度是与测量结果相关、表示被测量的量值分散性的参数,它是评定被测量的真值所处范围的一个参数。根据JJG700-1999《气相色谱仪检定规程》,按照不确定度评定原则,对一套气相色谱检定装置进行不确定度评定。%Uncertainty measurement is a parameter concerned with measuring results,which can show the dispersibility of the measuring subjects and which is to evluate the extent of the measuring value.This paper conducts the uncertainty evaluation of a set of gas chromatograp verification calibrating installation in accordance with the principles in Gas Chromatograp Verification Calibrating Standards(JJG700-1999).
