摘要

测量不确定度分析是大学物理实验课程中的重要内容之一。近几年,西南交通大学物理实验中心通过对学生相关不确定度分析知识的全方面讲授,深入地将其应用到大学物理实验内容设计的应用中,并取得了良好的效果。本文以单摆的研究、杨氏弹性模量测量、分光计测量三棱镜折射率3个实验为例,详细介绍了不确定度分析在大学物理实验教学中起的重要作用。通过将不确定度分析应用到实验内容的设计中,一方面可以加强本科生对大学物理实验课程的深入学习,另一方面可为培养学生的创新能力奠定基础。
        Measurement uncertainty analysis is one of the most important contents in university physics experiments course.In recent years,the physics experiment center of Southwest Jiaotong university has achieved a lot of useful results,based on the teaching experience of the related knowledge,then applying them to the designing of the physics experiments.This paper introduced the importance of uncertainty analysis in physics experiments education,using with three experiments,i.e.study on pendulum,measurement of Youngs modular,and measuring the refractive index of prism.By applying uncertainty analysis to the design of experiment content,on the one hand,it can strengthen undergraduatesin-depth study of college physics experiment courses;on the other hand,it can lay a foundation for cultivating studentsinnovative ability.
