| 摘 要： | 在控制测定条件,使测定的结果服从正态分布时,分光光度法的精密度和准确度将分别等于０．６６Ｒ和０．６６Ｒ／ｎ。Ｒ是样本极差（Ｘｍａｘ－Ｘｍｉｎ）,ｎ是样本大小（容量）。

| Abstract: | When the determination result is controlled to obey normal distribution,the precision "Pr" and the accuracy "Ac" of the spectrophotometry is equal to 0.66 R and 0.66 R/n respectively,that is Pr = 0.66 R and Ac = 0.66 R/n.R is the sample limit error (Xmax-Xmin)and n is the sample size. |
