板式惠斯顿电桥因为能简单而又直观地反映电桥线路的特点，便于观察并且适合手工操作而被大学物理实验广泛使用。文章分析了板式惠斯顿电桥在学生实验使用中两个严重故障的产生原因，采取几种不同的方式对电桥进行改进，并通过实际使用来验证改进的效果。板式惠斯顿电桥的改进研究有利于节约成本和减轻实验室技术员的工作量。%The plate type Wheatstone Bridge is widely used in college physical experiment, since it can simply and intuitively reflect the characters of bridge circuit, and in the meantime it is easy to process and observe. In this paper, the causes of two severe faults occurred in the Wheatstone Bridge experiments had been analyzed. To avoid these faults, several improved methods had been put forward. According to the actual effect, we found that all these improved methods were feasible. In addition, our methods are beneficial to cost saving and reducing the workload.
