摘要
微小形变电测法是大学物理实验中一个非常有特色的综合性创新实验。通过电阻应变片将悬臂梁的微小形变转变为电阻的变化,从而实现微小形变的电测量。结合实验中所蕴涵的国家重大需求及工程问题,以中国航空大型飞机和航母特种钢的设计与研制为例,融入课程思政内容,激发学生的学习热情和爱国热情,使学生综合素质得到全面发展,同时对大学物理实验的教学和研究也具有一定的指导意义和实践价值。
The electrical measurement of micro deformation is a comprehensive and innovative experiment with unique characteristics in the college physics experiment of our university.The micro deformation of cantilever beam is transformed into the change in resistance through the strain gauge,so as to realize the electrical measurement of micro deformation.It combines the national major needs and engineering problems contained in the experiment,takes the design and development of China’s aviation large aircraft and aircraft carrier special steel as examples.Thus,the ideological and political content of course is integrated,which stimulates the students’enthusiasm for learning and patriotism.So,students’comprehensive quality can be cultivated.At the same time,it also has a certain guiding significance and practical value for the teaching and research of college physics experiments.
