普通物理实验不确定度表示

The Express of Indeterminate Degree for General Physical Experiment

普通物理实验中有着大量的测量工作 ,学习与运用误差及实验数据处理的基础知识是工科普通物理实验教学的一个重要环节 .以往习惯使用误差进行数据分析 ,来评定实验测量结果 .为了在实验教学中逐步推行不确定度的概念 ,本文主要根据工科普通物理实验的特点 ,介绍如何用不确定度简化方法评定实验测量结果的优劣 ,让学生对不确定度的概念有更深的认识 .最后对分光计测棱镜折射率实验结果加以分析 .

There is much measurement in the general physical experiment.The fundamental knowledge of studying and applying error theory and experiment data processing is an important link in the general physical experiments of engineering courses.Usually data analysis is solved by the error theory and is to evaluate the measuring outcome of experiments.In order to form the indeterminate degree concept progressively in the experiment teaching,this article mainly introduces how to use a simple method of indeterminate degree to evaluate the superiority and inferiority of the measuring outcome of experiments according to the features of general physics experiments in engineering course.And it would also help students to grasp the conception of indeterminate degree more deeply.At the end of this article , it analyzes an experimental result which is attained by using spectrometer to measure the index of refraction of prism.
