摘要: 基于2008年及2009年分4个季节对北京市3种类型道路（开阔型、交叉路口型和峡谷型）空气中的NOx的现场监测结果，分析了3种类型道路空气中NOx的污染现状和时空变化规律及影响因素。实验结果表明，昼间北京市各类型街道空气中NOx浓度呈早晚浓度高、中午浓度低的变化规律，NOx浓度随季节和车流量变化较明显。交通道路空气中NO占NOx

Abstract: Based on field monitoring results of NOx concentrations on three types of roads (open road, crossroad, street canyon) in Beijing in four seasons of 2008 and 2009, NOx pollution status, temporal and special variation and the affecting factors were analyzed. The experimental results showed that NOx concentrations exist two peaks in the morning and evening. NOx concentrations are significantly affected by the traffic flow and the different seasons. NO concentration accounts for the high rate of NOx, and there is good correlation between NO and NOx, while it is contrary between NO2 and NOx.
