| 英文摘要 | featuring excellent response characteristics and detection sensitivity and with much lower operational cost, differential optical absorption spectroscopy (doas) can be a powerful tool to trace the concentration variation of carbon bisulfide (cs(2)), a kind of poisonous gas with bad smell. in the doas measurement, the accuracy of the carbon bisulfide results is determined by the selected spectral resolution. the present paper focuses on the effect of resolution on the detected characteristic absorption structure of cs(2) and the variation in differential cross section of cs(2) with the change in resolution, from which the effect of resolution on the detection limit of cs(2) is deduced. in the end, the functional dependence of the ratio of signal to noise (sin) on the resolution is reduced by studying the relationship between light intensity and resolution. and the optimized resolution is determined as 0.41-0.50 nm (fwhm) with the lowest sin. the optimized resolution range can yield high sensitivity, good selectivity and a reasonable time resolution for the accurate qualitative and quantitative analysis of cs(2) (the results of five different concentration cells show linear correlation with r=0.9999 and all the relative standard deviations are less than 0.3% with n=10). in the end, the long time, real time and continuous monitoring of cs(2) was carried out in the fengtai district of beijing, and a good result was obtained. |
