| 中文摘要 |
| 从城市街道汽车排放物扩散运动的基本物理过程出发,以城市街道CO浓度的监测数据为代表,分析了微尺度近场扩散过程的特殊性与主要参量,这些参量决定了污染模式的初始条件、边界条件、模式所涉及的范围和模式所能解决的问题。为建立城市街道汽车排放污染模式提供了一个物理基础。 |
| 英文摘要 |
| Based on the physical process of the vehicular emission dispersion in the urban street canyon, the monitored data of CO eoncentration near the urban traffic roads were analysed. The microscale near field dispersion model was particularly discussed,including the initial conditions, boundary conditions and the scope of the model as well as the problems that the model might deal with. |
