Issue Date: | 2001 | Source: | 环境科学 (Journal of environment science), Mar. 2001, v. 22, no. 2, p. 55-59 | Abstract: | 选取典型城市隧道进行机动车排放因子测试 ,应用隧道试验原理 ,通过连续 4 8h的现场采样监测 ,获得了隧道内机动车排放污染物NOx、CO、SO2 、PM10 、VOC和HC浓度、交通参数 (车型、车速、交通流量 )和气象参数(如风速、风量、温度、湿度 )等实测数据 .通过质量平衡计算出隧道内机动车NOx、CO、SO2 、PM10 和HC的平均排放因子分别为 1 .379、1 5 4 0 4、0 1 4 2、0 637、1 857g·(km·辆 ) - 1.并在此基础上应用多元回归方法计算出 8大类机动车各种排放污染物的单车排放因子 .结果反映目前中国城市机动车污染物排放水平及各污染物排放特征 . Applying the principle of tunnel test to run a typical across\|river tunnel test in Guangzhou city, 48h\|online\|monitor data include pollutant concentration, traffic activity and meteorological data were gained.The average motor vehicle emission factors of NO x , CO, SO 2, PM 10 and HC were calculated using mass balance which are 1 379, 15 404, 0 142, 0 637, 1 857g/km.vehicle respectively. Based on that, combined emission factors of 8 types of city vehicles were calculated using linear regressi... |
