| 摘 要： | 针对温度对SO2吸收截面的影响,本文提出在高温温度下对SO2吸收截面的温度特性进行研究.该方法采用浓度为10428.57mg/m3的SO2标准气体,在20℃、40℃、60℃、80℃、100℃等温度点处研究了高温温度与SO2吸收截面之间的定量关系,选用波长范围为吸收光谱检测SO2常用的紫外波段295～315 nm.通过对实验结果的定性和定量分析,得到了在不同波长处的SO2吸收截面与温度之间的定量关系式,并提出减小温度影响检测结果的方法.

| Abstract: | To find the quantitative relation of temperature and the absorption cross-section of SO2,the SO2 with the concentration of 10 428.57 mg/m3 is detected at temperatures of 20 ℃,40 ℃,60 ℃,80 ℃ and 100 ℃ in the wavelength range of 295 nm to 315 nm,which is often used during the measurement of SO2 absorption spectroscopy.Through qualitative and quantitative analysis on the experimental result,the quantitative formulas between temperature and SO2 absorption cross-section at different wavelength are deduced.Moreover,a new approach is put forward to decrease or compensate the error induced by the temperature. |
