摘　　要：通过对纳氏试剂光度法测定水质中氨氮的实验过程的分析,对此方法测量不确定度的评定,从而得出测量的重复性、标准溶液、使用的容量器皿、工作曲线等因素对测定结果的影响。Ammonia nitrogen in water quality was anaylzed by spectrophotometric determination using Nessler＇s Reagent spectrophotometry. Measurement uncertainty of this method to effect the results by repeatability standard solution, capacity containers, working curve, and so on, was studied.
