折射率的临界位置法测定实验设计及自主实践

Experiment Design and Independent Practice of Measuring Refractive Index by Critical Position Method

介绍了透明介质折射率的临界位置法测定实验的设计背景、目标、设计依据及测量方法。通过对不同水深条件下测量结果显著差异比较,引导学生分析原因,改进实验,减小误差。在探索不同因素对实验结果的影响及对实验的改进过程中,培养学生发现问题,分析问题,解决问题的能力及求真务实的品格。实验完成情况分析及信息反馈表明,实验设计获得了较好的效果,为实践课程中增设自主性实验项目提供了实践依据与参考。

This paper introduces the design background,purpose,design basis,measurement method and measurement requirements of the experiment for measuring the refractive index of transparent media by critical position method.The design scheme guides students to analyze the influence of water depth factors on the results by comparing the measurement results under different water depths,and then drives the students to explore the influence of various factors on the results and improve the experiment accuracy.In the process of exploring the influence of different factors on the experimental results and improving the experiment,the ability of students of finding,analyzing and solving problems and the spirit of seeking truth and pragmatism are comprehensively cultivated.The completion of the experiment and information feedback show that the experimental design has achieved good results,which provides a practical basis and reference for the work of independent practice project in the regular practice course after the epidemic.
