| 中文摘要 |
| 在１５６０ｍ 长的甘肃七道梁山岭公路隧道内设监测点，对进入隧道内汽车排出的污染物浓度、交通量、车种以及气象条件进行采样分析、计数、分类和观测．根据在隧道内实测数据，用建立的隧道空气质量方程计算出我国高海拔山岭公路汽车单车ＣＯ、ＨＣｓ和ＮＯx 排放系数分别为４１．８６１±２６．１０１、５．３６７±３．１５８和３．８８３±１．９４３ｇ／（ｋｍ ·ｖｅｈ）．与国外成果相比，我国山岭公路汽车ＣＯ和ＨＣｓ排放系数明显高于国外发达国家汽车的排放水平，而ＮＯx 排放量低于一些发达国家 |
| 英文摘要 |
| The measurements of the concentrations of the pollutants from the vehicles inside the 1560m-long Qidaoliang road tunnel in Gansu Province,the observations of meteorological conditions in the tunnel and the counting and classification of vehicles passing through the tunnel were conducted.The emission factors of CO,Hydrocarbons (HCs) and NOx from vehicles on mountain roadway in China were 41.861±26.101,5.367±3.158 and 3.883±1.943g/(km·veh),respectively,which were derived from the model of tunnel air quality based on the measured data.In comparison with the emission factors published by developed countries,the CO,and HCs emission factors of vehicles driving on mountainous road in China are much higher than those of the advanced countries.However,the level of NOx emission is lower than that of others. |
