摘　　要：以国际《测量不确定度表达指南》和国家计量技术规范《JJF1059-1999测量不确定度评定与表示》为依据,结合实验实践,阐述了不确定度的定义内涵、分析意义以及不确定度与误差的区别和联系,给出了用不确定度评定测量结果的一些方法。On the basis of the international standard ＂Guide to the Expression of Uncertainty in Measurement＂and the national measuring technique standard ＂JJF1059 - 1999 the Evaluation and Indicate of Uncertainty in Measurement＂, the definition of uncertainty is expounded in this paper.The difference and relationship between uncertainty and error in experiment is discussed. Several methods are put forward for evaluating experiment result with uncertainty.
