摘　　要：ＱＪ２３型电桥的面板上有７个接线柱，接线柱之间如果不接上连接片而连接外电路，则电桥变为检流计、电阻箱、限流电路或标准电阻．它们可以各自或联合运用一些设计性实验中，起到“集成电路”的作用．例如．联合运用到用ＤＣ－Ｉ型电势差计校准１．５ｍＡ安培计的实验．使这个实验接线大大简化。There are 7 wiring terminals on the board of the Wheatstone Bridge. If the terminals are not linked up with the linking clips but to the external circuits,the WbeatstoneBridge will become the galvanometer,the resistance box,the current limiter,or the standard resestor,which may be used respectively or together in some self-designed experiments,serving as an 'integrated circuit'. For instance,they may be used unitedly in theexperiment in calibrating the 1. smA ameter with the DC-I potentiometer,greatly simplifying the experiment in wiring.
