The precision of an analytical procedure is usually expressed as the standard deviation or relative standard deviation (coefficientof 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。

A function of probability distribution of fading is derived and the deviationcoefficient and probability coefficient of field strength are obtained.
并研究场强沿铁路的起伏规律，导出场强起伏的概率分布函数，得到场强偏差系数和概率系数。

It has also been shown that this deviation is more than just addition of linear loss coefficient especially when long haul fiber optic systems with inline amplifiers are considered.
