①对每个操作者的一组独立测量结果,在技术上说明可疑值的产生并剔除后,可用格鲁布斯(Grubbs)法或狄克逊(Dixo)法从统计上再次剔除可疑值。当数据比较分散或可疑值比较多时,应认真检查侧量方法、侧量条件及操作过程,列出每个操作者侧量结果的原始数据、平均值、标准偏差及侧量次数。

3.在数据服从正态分布或近似正态分布的情况下,将每个实验室所测数据的平均值视为单次测量值,构成一组新的测量数据。用格鲁布斯法或狄克逊法从统计上剔除可疑值。当数据比较分散或可疑值比较多时,应认真检查每个实脸室所使用的测量方法、侧量条件及操作过程。

式中:c 1- 一级标准气体的浓度(已知八,
            h 1- 一级标准气体色谱峰高吸测得八,
            c 2- 二级标准气体的浓度(待求),
            h 2- 二级标准气体色谱峰高(测得)。

假设:s 1、s 2、 s 3、 s 4分别表示c 1、c 2、h 1、h 2的标准偏差,则有:

即二级标准气体浓度的标准偏差是由一级标准气体浓度c1和峰高h1的标准偏差及二级标准气体峰高h 2的标准偏差合成而得到的。
