摘　　要：为了解流动注射法测定水中挥发酚过程中产生的不确定度,分别从标准贮备液质量浓度引入、标准溶液配制与稀释过程、配制标准溶液系列各浓度点、由流动注射法曲线拟合求得水样质量浓度。通过样品重复性测量五个方面引入的不确定度,建立数学模型,获得最终的不确定度。In order to understand the uncertainty in the determination of volatile phenols in water by using flow injection analysis,separately from the standard solution concentration introduced,the preparation and dilution process of standard solution and preparation of the series of standard solution concentrations,the phenol quality concentration in water samples is obtained by flow injection method using curve fitting. By repeated determination of samples with uncertainties caused by the fove aspects,the mathematic model is established and the final uncertainty can be gained.
