摘　　要：环境监测中,测定水中氨氮常采用纳氏试剂光度法,测量结果的不确定度非常重要。通过大量实验研究,得出纳氏试剂先度法测量不确定度评定,应考虑工作曲线、测量重复性、标准溶液、仪器读数分辨率等影响评定测定结果几种重要因素。The uncertainty degree is very important in measuring ammonia nitrogen in water by Nesster＇s reagent spectrophotometry. The determination of uncertainty degree should consider the impacts of working curve, testing repeatability, standard solution and reading resolving power, among others.
