摘　　要：本文利用SKALAR SAN++型连续流动分析仪测定水中的氨氮,从氨氮标准储备液、标准溶液配制、标准曲线拟合、样品重复性测定和连续流动分析仪这几个方面对不确定度、合成标准不确定度(u)和扩展不确定度(U)进行计算。Ammonia nitrogen in water is determined by continuous flow analysis.The uncertainties of standard stock solution as well as standard solution confecting,standard curve,repeatability and continuous flow analyzer are evaluated.And then the synthetic uncertainty and expanded uncertainty are calculated.

关 键 词：连续流动分析法 氨氮 不确定度
