摘要/Abstract

摘要： 指出传统伏安法测量中值电阻时, 由于电流表的内接法或外接法会给测量结果带来系统误差。介绍了用电压补偿伏安法测量电阻的原理, 给出了内接法、外接法及补偿伏安法测量电阻的相对标准不确定度的计算公式, 并对其不确定度进行比较, 对测量数据进行了处理, 给出待测电阻的测量结果和不确定度及误差的计算结果。

关键词: 　补偿法, 伏安法, 　电压, 　电阻, 　不确定度

Abstract:

　 While measuring central value resistance with traditional voltammetry , either the internal connecting method or external connecting method of an ammeter brings system errors of measurement results. A new method of measuring resistance with the voltage compensation voltammetry principle was described. A formula of relative standard uncertainty was given,which measured resistance with internal connecting method , external method, and voltage compensation voltammetry . With comparing the uncertainty , the measurement data were processed. The measurement results of resistance , uncertainty and computing results of errors were provided.

Key words: Compensation method, , Voltammetry, , Voltage, , Resistance, , Uncertainty
