| 摘 要： | 在室温条条件下，以Xe灯为光源，利用SO2的紫外吸收光谱，研究了SO2的浓度随时间连续变化规律。实验中考虑了温度和充垫气体N2对SO2的浓度变化的影响。实验结果表明：SO2的浓度基本上是随时间线性变化的；同时，SO2的浓度变化率与光照时间有关。

| Abstract: | The SO2absorption spectrum is recorded using Xe lamp source under atmospheric conditions at ambient temperatures. The SO2concentration is retrieved to study the relation between SO2concentration and time. In this experiment, effects of temperature and the buffer gas N2are also considered. It is demonstrated that the concentration of SO2decreases in a linear relation to the time and the period of illumination may have effects on the rate of decrease. These results are applicable to SO2pollution monitoring in the atmosphere using high resolution spectrometer and differential absorption lidar. |
