摘　　要：针对大学物理实验教学过程中学生处理数据普遍存在的不确定度概念不清、计算公式使用不当做了仔细分析探讨,试图从五个方面分析由来已久的不确定度计算出偏导致实验结果表达不规范的问题。In this paper,a common college physics experiment teaching high school students to process data uncertainty concept is unclear, the formula is not as careful analysis of explore, and attempt to re- solve long-standing uncertainty discussed from four aspects to calculate the partial cause experimental the results express the non-standard problems.

关 键 词：不确定度 直接测量 间接测量 合成不确定度
