First, based on the measurements of absorption cross-section, the absorption characters of the main polluted gases in flue gas were deeply studied, and found that SO_2、 NO、 NO_2、 NH_3 had a character of approximate periods absorption at some wave band, which is a good chance of a new measurement introduced. Secondly, the factors about absorption cross-section of the gases measured, which affect on the measurement precision of DOAS, is studied deeply. The influence of pressure and temperature on absorption cross-section was given special research, and the compensated measures were given to the gases based on the character of the gases. Thirdly, in practical measurement, it must have been satisfied that the monochromator was consisted with the reference spectrum, which was based on absorption cross-section. In order to satisfy the consistency, the technique of reversion in the image was introduced, the reversions of spectrums were realized with wiener filter and noise elimination based on wavelet transform.
首先从吸收截面的测量入手,对烟气中主要的污染气体SO_2、NO、NO_2、NH_3的吸收特性进行详细研究,发现这些气体在局部区域具有准周期吸收特征,这为引入新的测量方法提供了契机;其次,对决定DOAS测量精度的被测气体吸收截面的诸多问题进行了深入研究,重点研究了压力、温度对被测气体吸收截面的影响,并针对被测气体的特征提出了相应的修正措施;再次,在实际测量中,要求所使用的光谱仪必须与以吸收截面为基础的参考光谱相匹配,为了满足匹配这一条件,文中将图像复原技术引入到光谱复原,使用维纳滤波和小波消噪实现了光谱的复原,将复原后的光谱与所使用光谱仪的仪器函数卷积,即可实现;最后,在对DOAS测量原理详细分析的基础上,对传统的最小二乘—差分吸收光谱法进行了详细的阐述,通过实验证实两点:1。
