摘要
介绍了实验测量中 A类、 B类不确定度及扩展不确定度等有关概念 .结合普通物理实验的具体情况 ,利用相关概念 ,提出一种在高置信概率情况下使用简化的方法来分析实验的误差 ,表述测量结果 .采用该方法具体分析了电位差计实验的实验误差及测量结果的表述 。
This paper gives an introduction to the concepts of Indeterminacy Type A,Indeterminacy Type B, and indeterminacy by extension in measurement for experimental purposes, then goes on to present a simplified method to analyze and describe experimental errors especially in potentiometer a measurements.Both the analysis and the description are proved to be well within high confidence probability and claim many advantages as a necessity for college physics experimentation teaching.
