摘要
介绍了第7届全国大学生物理实验竞赛综合研究性实验试题C的实验原理、试题内容及答案,并对参赛学生的考试结果进行了评析.综合研究性实验试题C为基于给定条件搭建黑箱光路,包括3部分:晶体偏振光学元件的识别,光传输路径的控制,探究偏振在光测弹性应力测试中的应用.试题突出了理论分析与实验技能相结合,考察学生知识积累、知识获取、方案设计、系统搭建、结果分析的综合实验能力.
The experimental principle,content and answers of the comprehensive test C of the 7th Chinese Undergraduate Physics Experiment Competition were introduced,and the analysis of the students’exam result was given.The task of the comprehensive test C was to build the black-box optical path based on given conditions,including three parts:the identification of crystal polarization components,the control of optical transmission,and the exploration of the polarization in photometric elastic stress testing.The comprehensive test C was highlighting the combination of theoretical analysis and experimental skills,to examine the comprehensive experimental ability of students’knowledge accumulation,knowledge acquisition,program design,system construction and result analysis.
