摘要

基于误差理论,以扭摆法测量金属丝的切变模量实验为例，对其直接测量量的系统误差、偶然误差进行了分析判断，借助excel数据处理工具，用标准不确定度的数据处理方法求解金属丝切变模量，以帮助学生了解和掌握物理实验误差和数据处理的基本方法。

Abstract:

Based on error theory, taking the experiment of measuring shear modulus of wire by torsional pendulum method as an example, the systematic error and accidental error of direct measurement are analyzed and judged. With the help of excel data processing tool, the shear modulus of wire is solved by data processing method of standard uncertainty, so as to help students understand and master the basic method of physical experiment error and data processing.

Key words: error theory shear modulus data handling
