提高单臂电桥灵敏度的理论与实验分析

Improve the Theory of the Single Electric Sensitivity of Bridge of Arm And Experimental Analysis

电桥的灵敏度与检流计和电源所接的位置有关,通过数学推导和实验测量得出结论:当D>0检流计内接时,电桥灵敏度较高;当D<0检流计外接时,电桥灵敏度较高。

The sensitivity of the electric bridge relates to examine and flow and count with the position connected of power, derive through mathematics and the experiment measure the conclusion of drawing. When D>0 is examined and flowed and connected while counting, the electric bridge is relatively high in sensitivity. Act as D<0 examines and flows it while counting outerly, the electric bridge is relatively high in sensitivity.
