摘要: 不确定度是大学普通物理实验课中重要的新概念,入学不久的大学生因缺乏概率分布方面的必要基础知识,在最初接触不确定度概念及其相关公式时,普遍存在理解和运用的困惑.本文以计算间接测量量折射率的不确定度为例,尝试化解这一教学难题.

Abstract: Uncertainty,as a new concept of college physics experiment,cannot be understood and applied well by freshmen due to the lack of the basic knowledge on probability distribution. In order to reduce the difficulty of learning uncertainty,a teaching effort is paid by showing how to calculate the uncertainty of the refractive index.

Key words: uncertainty, general physics experiment, indirect measurement, refractive index, experimental teaching
