【摘要】 将惠斯登电桥的桥臂两端加一换向开关 ,可保证在相同的条件下交替重复测量比较臂的电阻RS1和RS2 ,从而消除由倍率带来的系统误差和测量过程带来的偶然误差 ,提高测量效率。并将测量结果进行不确定度估算 ,用Rx=(Rx±U)Ω的式子将结果进行规范科学的表示出。更多还原

【Abstract】 Using the same standard electric resistance galvanometern the etc.the equipments,and measuring the mensurationn electric resistance of needing of different quantity class respectively,and drawing to give orget an electric shock the bridge nearby equilibrium,the relation curve of the magnification and intelligent degree,find out under the same alike of the equipments term,electricity bridge is nearby equilibrium tallest the best magnification of nitelligent degree is constituted the quantity class of the magnification’s two electric resistances and need the mensurationn electric resistance quantity class the equality,and the specific value is for the magnification that 1.更多还原
