| 摘 要： | 由电桥灵敏度的定义可知,△n是对应于待测电阻的相对改变量,而引起检流计中的偏转量,所以电桥灵敏度越大,对电桥平衡的判断就越容易准确,测量结果也更准确.那么用实验方法测定电桥灵敏度时,△n取值是多少格合适?本文用实验方法探讨了检流计偏转格数与电桥灵敏度的关系.

| Abstract: | According to the definition of electric bridge sensitivity. It can be seen that An is the galva- nometer deflection number that the relative change corresponds to the test resistance, so the greater the electric bridge sensitivity, the easier to determine electric bridge balance and the more accurate measurement results. Experiments for measuring the sensitivity of electric bridge, what value is suit able about An？ This paper explores the relationship between galvanometer deflection and the electric bridge sensitivity by experimental methods. |
