一等标准电池标准装置不确定度评定方法

A Method in Evaluation of Uncertainty of First Standard Cell Verification Device

介绍了一等标准电池标准装置的组成、工作原理,推导出差值替代法检定二等及以下级别的标准电池的数学模型,并给出了该装置不确定度来源及评定方法。

The paper introduces the composition and principle of the first standard cell verification device. Then, it deduces the mathematical model of the second and the below standard cell. It derives the source of the uncertainty, and gives a method of evaluation on uncertainty with the way of replacing the difference.
