【摘要】 选取广州城市隧道进行连续 48h的监测 ,获得了隧道内NOx,CO ,SO2 ,PM1 0 和HC等污染物的浓度、交通和气象等实测数据 ,计算出隧道内机动车NOx,CO ,SO2 ,PM1 0 和HC的单车平均排放因子分别为 1 3 8,15 40 ,0 14 ,0 64和 1 86g (km·辆 ) ,并得到了 8类机动车各种排放污染物的综合排放因子更多还原

【Abstract】 By running a tunnel test in Guangzhou, a continuous 48 h monitoring data for the concentration of pollutants (NO\-x, CO, SO\-2, PM\-\{10\} and HC), traffic and meteorological data were obtained. The average motor vehicle emission factors of NO\-x, CO, SO\-2, PM\-\{10\} and HC were then developed, which is 1.38, 15.40, 0.14, 0.64, 1.86 g/(km·vehicle) in sequence. The combined emission factors of 8 types of vehicle were also developed.更多还原
