The electrical measurement of micro deformation is a comprehensive and innovative experiment witunique characteristics in the college physics experiment of our university.The micro deformation of cantileveleam is transformed into the change in resistance through the strain gauge, so as to realize the electricameasurement of micro deformation.lt combines the national major needs and engineering problems contained inthe experiment,takes the design and development of China's aviation large aircraft and aircraft carrier speciasteel 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 thesame time ,it also has a certain guiding significance and practical value for the teaching and research of collegephysics experiments.
