| 摘 要： | 为了测定我国城市道路机动车污染物排放因子，在西安城市交通隧道内设３个空气监测点，对通过隧道的机动车排气形成的污染物浓度、隧道内风速、过往隧道的交通量以及车型进行采样、观测、统计和分类根据测试数据用大气扩散方程求得我国城市道路机动车平均单车 ＣＯ、 ＨＣ和 ＮＯｘ排放因子分别为 ３３．２７９±１２．１５８、 ３．５７７±１．８１６和 ４．６０５±１．９８１ ｍｇ／（ｍ·ｖｅｈ）．与国外的成果相比，我国城市道路机动车ＣＯ、 ＨＣ和ＮＯｘ排放因子分别是发达国家城市道路汽车排放因子的 ７～８倍、 ８～１０倍和 ３～４倍.

| Abstract: | At three monitoring points established inside the Xi'an urban road tunnel, measurements of concentrations of the pollutants from motor vehicles, observations of meteorological conditions in the tunnel and counting and classification of vehicles passing through the tunnel were conducted. The emission factors of CO, HC and NO. from the motor vehicles on urban main road in China were 33.27912.158, 3.5771.816 and 4.6051 .981 mg/(m.veh), respectively, which were derived from the atmospheric diffusion equation based on the measured data. In comparison with those in the developed countries, the CO, HC and NO. emission factors of the motor vehicles on urban main road in China are nearly 7-8 bines,8- 10 times and 3-4 bines, respectively. |
