摘　　要：惠斯通电桥和交流电桥实验是中高等实验教育中的重要组成部分,针对学生普遍原理理解相对容易、实验操作能力相对薄弱的问题,采用电路模块化分层教学和线色标识的方法,大大提高了学生对实验电路结构的理解,极大地提高了组建电路的效率,让学生把主要精力放在实验现象探索和实验规律的研究当中,很好地提高了教学效果,因此本方法可以推广到其他类似的或者更复杂的电路实验当中。Wheatstone bridge and AC bridge experiments are important parts in middle and higher experimental educations.In view of simple principle of the circuits and weak experimental operational ability for students,we adopted modularized circuit and color wire marking methods to greatly give the deep insight into the experimental circuit structures and to improve the efficiency of the building circuits.The method makes students mainly focus on experimental phenomena and experimental law and greatly improve the teaching efficiency.So the method can be extended to other similar or more complex circuit experiments.
