原始语种摘要: Nitric oxide (NO) and nitrogen dioxide ( NO2 ) are relevant to airquality due to their roles in tropospheric ozone ( O3 ) production. InChina, NO x emissions are very high and NO x emissions exhausted from on-roadvehicles make up 20 % of total NO x emissions. In order to detect the NOand NO2 emissions on road, a dual-channel cavity ring-down spectroscopy(CRDS) system for NO2 and NO detection has been developed. In thesystem, NO is converted to NO2 by its reaction with excess O3 in the NO x channel, such that NO can be determined through the differencebetween two channels. The detection limits of NO2 and NO x for thesystem are estimated to be about...
