摘　　要：电桥电路由于测量精度高、方法巧妙 ,在电磁测量技术中有极其广泛的应用 ,不仅可测电阻、电容、电感 ,而且在非电量电测技术上应用也十分广泛 ,如力、位移、形变、温度、湿度、压力等量的测定。通过充实拓展了直流电桥实验内容 ,既保证了基本实验的训练要求 ,又能以应用为背景的新知识来激发学生的学习兴趣和积极性 。Electric bridge circuit is widely applied to electromagenetic measurement for its accuracy and efficiency.It can be exploited to measure not only resistance,electric capacity,inductance,but also such non-electrical properties as strength,displacement,deformation,temperature,humidity,and pressure.Thus,the experiment introduced in this paper can not only become a nourishing addition to the relevant curriculum,but also arouse students' interests in the subject and enrich students hands-on experience.
