摘　　要：通过自制传感器将交流电桥实验与测量相对位移、转动角度结合起来,既加深了学生对交流电桥原理的认识,又让其体会到力学量电测法的具体运用。In this paper, we combine the alternating current bridge with the measurement of relative displacement and turn angle by self-made sensors. Through this experimental, not only to deepen the students understanding of the principles of alternating current bridge, and allowed to appreciate the mechanics of the specific amount of electrical measuring method to use.
