The precisionof an analytical procedure is usually expressed as the standard deviation or relative standard deviation (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。

With the error network parameters, the real network's input reflecting coefficient is revised and the measurement precisionof measuring line system is improved.
利用误差网络参数，对被测网络的输入反射系数进行误差的自动校正，提高了测量线测试系统的测量精度。

The system also could decrease the effect of scattering light on absorption coefficient measurement by partly plating highly reflective membrane, so that we can improve the precisionof the system.
