| 摘 要： | 本文基于HJ194-2005和HJ482-2009,建立了分光光度法监测空气中SO2不确定度的数学模型,分析了在24 h连续采样、手工分析方法监测空气中SO2过程中,影响监测结果不确定度的因素(如温度、大气压、仪器流量、容量器皿刻度精度等),并对其影响进行了量化评估,得出了环境空气中SO2监测过程中的不确定度。

| Abstract: | Mathematical model of uncertainty of SO2 in the air monitoring by Spectrophotometry has been built based on HJ194-2005 and HJ482-2009.The impact factors on uncertainty of SO2,such as temperature,Atmospheric pressure,instrument flow capacity,scale and accuracy of vessels,have been studied and quantitatively evaluated by 24h continuous sampling and hand analysis.The uncertainty of SO2 in the air was got during sample monitoring. |
