不确定度在工科基础物理实验中的应用举例

THE APPLICATION EXAMPLE OF UNCERTAINTY IN BASIC ENGINEERING PHYSICS EXPERIMENTS

本文扼要地介绍测量不确定度的定义及计算方法,并针对大学低年级工科基础物理实验的要求,列举了在基本测量实验中求铜管体积的具体应用,希望学生淡化误差,养成不确定度应用于数据处理中的良好习惯。

This paper briefly introduces the definition of measuring uncertainty and its calculation methods. Measuring and calculating the volume of one copper tube is taken as an example, to meet the requirement of the fundamental physics experiments for junior university engineering students. Through this example, students are expected to fade out the concept of error and form the good habit of applying uncertainty to experimental data processing.
