摘　　要：报道了长安、帕萨特和桑塔纳三种品牌轿车在正常行驶过程中车内外CO和NOx浓度的测定结果.结果表明:车内CO浓度超过三级浓度限值,NOx浓度均低于一级浓度限值;车内CO和NOx浓度水平都高于车外;慢速和堵车时出现时车内CO浓度增高;车窗关闭并开空调情况下,车内CO浓度累积升高趋势.CO and NOx concentrations inside/outside saloon cars （CHANGAN, PASSAT and SANTRA） were determined during their ordinary running. It showed that the CO concentration inside the saloon cars exceeded the National Air Quality Standard Grade Three, but NOx concentration insidethem met the National Air Quality Standard Grade One. The CO and Nox concentrations inside the saloon cars were higher than those outside them. The CO and NOx concentrations inside the saloon cars increased when they ran slowly or were in a traffic jam. CO tended to accumulate inside the cars with their windows closed and their air conditioners on.
