误差与不确定度在物理实验教学中的重点把握及应用

Understanding and Application of Error and Uncertainty in Physical Experiment Teaching

对大学物理实验中的测量误差与不确定度概念以及它们之间的区别与联系做了阐述,在大学普通物理实验中引入不确定度表示是非常必要的,给出了简化的实验结果不确定度的表示式和计算流程,使之容易被学生掌握和应用.

This paper explains concepts of ＂the error of measurement＂ and ＂the uncertainty of measurement＂ in the college physics experiment,and discusses the relationship and difference between them. It is necessary to introduce the expression of uncertainty of date processing in the college physics experiments and a reasonable simplified expression and flow chart of uncertainty calculation which is easy for college students to learn and grasp.
