Throughout the entire intercomparison process, it's desirable to establish the stability of a measured cell difference by calculating a standard deviation across several redundant readings.

在整个比对过程中，我们希望得到被测电池电压差的稳定性指标。方法是从几个冗余的读数计算出其标准偏差。

Accuracy of the CT method was calculated as the average difference between methods. Precision was measured as the standard deviation of the CT measurement.

以这两种方法间的平均差异来计算ct的准确性，以CT测量结果的标准差评估精确度。

There is no significant difference between the result of the method and that of micro-Kjeldahl′s method according tot test. The relative standard deviation is 3.1%.

经t检验证明，该方法的测定结果与微量凯氏定氮法无显著差异，测定结果的相对标准偏差为3.1%。
