| 摘 要： | 通过对北京城市3种典型交通道路空气中NOx的时空变化监测发现,城市道路空气NOx中NO分担率主要集中在31.6%～81.1%,明显高于非交通道路中NO的分担率(3.0%～34.0%).其原因是NO主要来源于机动车尾气的排放.利用MOBILE软件计算了各类机动车排放的ρ(NOx),并相应地确定了影响交通道路中ρ(NOx)的敏感因素.据此提出了北京市交通道路空气中NOx若干控制措施,如控制车速、车型、油料等.

| Abstract: | NOx monitoring results of temporal and spatial variation of air quality in Beijing near three typical urban traffic roads showed that the NO contribution ratio of NOx is 31.6%-81.1% on the road, which is significantly higher than that in non-road areas, which is 3.0%-34.0%. The reason is that the NO on the traffic road comes primarily from vehicle exhaust emissions. NO exhaust emissions of vehicles on urban roads were calculated using the MOBILE model, and the sensitivity factors were correspondingly determined. Some control measures for NOx are suggested. |
