摘要
在拉伸法测金属丝的杨氏弹性模量实验中,对结果的不确定度的评定一般有多种方法.笔者讨论了教学中用逐差法处理数据时不确定度的简化评定方法:单次测量量根据具体实验条件进行估计,多次测量量采用合成法.
In the experiment of measuring Young＇s elasticity modulus of metal filament by using tensile method, generally there are a number of ways to measure the results of the evaluation of uncertainty. This paper mainly discusses the simplified evaluation of uncertainty which processed by method of successive minus in teaching ： measuring the volume of a single experiment in accordance with the terms of the specific estimates, repeated measurement using synthetic method.
