| 摘 要： | 差分吸收光谱法是利用气体污染物在UV-VIS波段对光有不同的吸收特性来测量其平均浓度。利用DOAS原理对不同浓度的SO2、NO2、NO气体进行排放监测实验研究,表明:DOAS可消除烟尘颗粒等影响,可应用于气体固定污染源的排放监测,但必须修正温度等因素对差分吸收特性的影响。

| Abstract: | Differential optical absorption spectroscopy (DOAS) makes use of the flue gas pollutant different optical absorption characteristic at the UV-VIS wave band to measure their average concentration.By DOAS principle,experimental study was carried out to measure different concentration of SO_2,NO_2 and NO.The DOAS technology can eliminate the influence of dust etc.The DOAS can be applied to monitoring the flue gas emission concentration and should correct the temperature effect on flue gas differential absorption characteristics. |

| Keywords: | flue gas continuous emission monitoring differential optical absorption spectroscopy (DOAS) gas contamination and on-line monitoring |
