摘要
极差法是估算A类不确定度的一种有效方法,而在物理实验教材中却少有介绍.本文以杨氏模量测定实验为例用极差法估算了不确定度,并与用贝塞尔法计算的结果进行了比较.
Range method is an effective method to estimate the uncertainty of the class A, but few introduced in the physical experimental teaching materials. The uncertainty in the experiment of Young' s modulus is estimated with range method in this paper, and compared with the Bessel method' s results.
