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.
