板式电位差计测量电池电动势的不确定度评定

The Uncertainty in the Measurement of Electric Potential of Battery by Planar Electric Potential Difference Meter

用适当简化处理的不确定度计算方法,分析板式电位差计测量电池电动势实验测量结果的不确定度,给出一种合理的不确定度评定方案.

Adopting a simplified calculation method of uncertainty degree, thispaper analyzes the uncertainty degree of results in measuring the electric potential of battery by planar electric potential difference meter and figures out a reasonable method to assess the experiment result of uncertainty degree.
