摘要
本文在理论上从灵敏度的定义以及能量观点对直流单臂电桥(惠斯登电桥)的灵敏度作了论证。证明了该电桥不存在灵敏度最大的工作状态,并指出了等臂电桥并非在任何情况下灵敏度都高。以上两点笔者与有关文献的结论不同,最后对实验中的作法作了理论上的解释。
This paper theoretically deals with sensitivity of Wheatstonc bridge with the view of energy and definition of sensitivity .It presents a proof that no maximum sensitivity working state exists for the bridge .It also points out that the sensitivity of equal bridge is not always high under any circumtances.The above two conclusions reached in the paper controdi(?)t those reached in the other papers .
