摘　　要：随着测量不确定度理论的发展,合理评定测量不确定度已成为校准和检测实践中一项重要和必要的工作;国际标准化组织(ISO)协同国际计量局(BIPM)等国际组织2008年修订了"测量不确定度评定导则"(GUM)并正式颁布了其"补充件一"。结合化学分析的实例,对新的测量不确定度评定规范化文件在实际应用中的相关问题作一些分析和介绍,以期提供有益的思路。With the development of the theory of measurement uncertainty, evaluating measurement uncertainty reasonably has become an important and necessary work in calibration and test practice. Cooperating with BIPM, in 2008 ISO has reviewed ＂Evaluation of measurement data-Guide to the expression of uncertainty in measurement＂ （GUM） and issued formally ＂Evaluation of measurement data-Supplement 1 to the GUM-Propagation of distributions using a Monte Carlo method＂ . This paper tried to describe relative problems on using new standards with an example of chemical analysis, and provides an useful and practical idea.
