摘　　要：主要阐述了气相分子吸收光谱法测定氨氮的校准曲线斜率、截距参考值的分析。文章收集了临安市环境监测站实验室自2012年以来气相分子吸收光谱法氨氮校准曲线制作的一系列原始数据,并通过数理统计方法对校准曲线、残余标准偏差、斜率扩展不确定度、截距扩展不确定度开展了详细讨论,得出气相分子吸收光谱法氨氮校准曲线截距a值、斜率b值实验室参考值。此结果对实验室分析人员判定氨氮项目校准曲线制作是否合格具有一定的参考价值。This paper mainly analyzed the reference value of the slope rate and intercept from the ammonia nitrogen＇s calibra- tion curve by using gas - phase molecular absorption spectrometry. According to the raw data of ammonia nitrogen collected by Linan Environmental Monitoring Station from 2012, the reference value of the slope rate and intercept of calibration curve＇s ammo- nia nitrogen were obtained based on discussing the calibration curve, residual standard deviation, uncertainty of the slope rate and intercept. These results provides reference for determining eligibility criteria of calibration curve from ammonia nitrogen.
