摘要
针对城市大气污染的复杂多变状况 ,在理论分析的基础上 ,通过风洞实验对城市大气污染扩散模型进行了模拟试验研究 ,建立了适合一定条件下城市大气污染物扩散的数学和物理模型 ,并对城市大气污染状况的影响因素进行了分析 ,在得到特定条件下城市大气污染扩散普遍规律的同时 ,重点讨论了风向变化对城市大气污染的影响 。
In view of the complex changeable condition of the city's air pollution, this article has conducted the simulation research through the wind tunnel modeling test on the basis of theoretical analysis, established mathematics and physical air pollution model fit for city's situation under the certain condition, discussed how the wind direction's change affects the urban air pollution while obtain the general rule of the atmospheric diffusion in city, the method also can be used in estimate the air pollution.
