【摘要】 本文通过理论分析,探讨了决定惠斯通电桥静态灵敏度的因素,然后用Mathematica软件进一步探讨了惠斯通电桥桥臂电阻在各定值平衡条件附近的变化规律,找出了单臂电阻变化(静态)时电桥高灵敏度的条件。更多还原

【Abstract】 Through theory analyzing, the paper discussing the most determinant factor of sensitivity of the wheatstone bridge, and the variation rule of brachium points of the wheatstone bridge which exist as each constant condition of balance is also discussed by using the soft of mathematica, the author gets the condition of high-sensitivity of the wheatstone bridge with the changing resistance.更多还原
