【摘要】 污染物在大气中被稀释扩散时 ,还会发生干沉积、湿沉积和化学转化过程 ,所有这些都会影响污染物在大气中的分布。目前高斯模型对污染物的非扩散过程基本不考虑 ,使得环境影响评价中城市尺度的大气预测结果不合理 ,因此提出干湿沉积化学转化综合公式 ,指明了各个参数的计算方法 ,并以上海市化工区为例进行应用计算更多还原

【Abstract】 Air diffusion can impact the pollutant distribution in atmosphere, and so do some non-diffusion aspects such as dry sediment, wet sediment and chemical translation. Without taking these non-diffusion aspects into account, people may get unsuitable results when using Gauss model to assess atmospheric impact within city scale. Thus the integrate formula about dry sediment, wet sediment and chemical translation was brought forward in the paper, moreover there were some calculations about Shanghai Chemical and Industrial District.更多还原
