| 摘 要： | 本文阐述了用电位差计测量电池电动势的测量误差是由系统误差,偶然误差和灵敏度组成,其值的大小由电位差计的等级,等测电动势大小和标准电池的等级以及所用检流计的灵敏度决定.测量误差最终又决定测量结果的有效数字和电位差计应匹配的标准电池及检流计.

| Abstract: | In this paper, it was described that the errors of the measuring value of a batteryelectromotive force with a potentiometer composed of the system errror, the radom error andthe detectivity. The errrors were evaluated from therr grade of the potentiometer, the valueof the battery electromotive force to be measured and the grade of the used standard batteryas well as the sensitiveness of a current detector. The available numbers of the battery elec-tromotive force amd the selections of the standard battery amd the current detector were de-termined by the measured error. |
