The precision of an analytical procedure is usually expressed as the standarddeviation or relative standarddeviation (coefficient of variation) of a series of measurements.
分析规程的精密度通常以一系列测量数值的标准差或相对标准差(变异系数)来表示。

Using the standarddeviationcoefficient as analysis target, the author provides a new probability analysis method, in case the mathematical expectations are different.
提供了一个在数学期望值不相等条件下进行概率分析的新方法，该方法采用所谓标准差系数作为分析指标。
