测量结果表达式与不确定度关系的研究与探讨

Research on the Relationship between Expression and Uncertainty of Measuring Result

测量不确定度和结果表达是学习物理实验的重要概念,它是衡量测量结果可靠性和准确程度的标志。本文就这些概念以及它们之间关系一一进行阐述,以有利于学生学习与参考。

The expression of measuring result and uncertainty are the important concept in the proces- ses of physical experiment study. They also are the important standard to judge the degree of reliabili- ty and accuracy of measuring result. In this paper, these concepts and their relation were discussed one by one. These concepts explaining and deriving are beneficial to student＇s study.
