摘　　要：参照国家标准GB/T10781-89,采用气相色谱法测定白酒中己酸乙酯含量。通过对己酸乙酯的测定进行测量不确定度的评估实验,介绍了一种内标定量法的测量不确定度评估方法,表达出了合成标准不确定度和扩展不确定度,为白酒质量控制提供有效、可靠、可溯源的测量数据。To base on GB/T10781.8-89, the content of ethyl caproate can be determined with gas chromatography. By the experiment of the uncertainty measurement of the ethyl caproate in Chinese spirits this paper expounded a method to evaluate the uncertainty measurement for inner standard method. At last the combined standard uncertainty and the expanded uncertainty are expressed, which provide the effective and credible quality data to the quality control.
