| Abstract: | As the main factor affected the precision of the differential optical absorption spectrometry(DOAS),the absorption cross section and its measurement theory was analysed.A new measurement setup was brought forward,and throgh which the absorption cross sections of SO 2,NO 2 and O 3 were measured.At last according to the measurement result,the respective appropriate wavelength ranges of three gases measured by DOAS were analysed. |
