摘　　要：利用环境监测长期积累的标准样品的定值数据、实际废水样品重复测定的数据以及大量能力验证数据,进行质控数据的统计分析,以评定环境监测过程中的测量不确定度。以水质监测中COD、总磷和总硬度的不确定度评定作为实例,推选一种简单实用的精密度评估法。In order to evaluate measurement uncertainty in the process of environmental monitoring, statistical analysis of quality control was made with certified value data of standard sample, repeated measurement data of real wastewater sample which were long term accumulated in environmental monitoring and a large number of proficiency testing data. A simple and practical precision estimation method was put forward with the uncertainty evaluation of COD, total phosphorus and total hardness in the water quality monitoring as examples.
