摘要
以SO_2在大气中的传播,扩散和化学转化为例,提出了沿海热力内边界层中污染物的扩散与化学转化模式。研究表明,由于化学转化作用,一部分SO_2继生污染物,将以SO_4^(2-)形式存在于大气中。SO_2及其继生污染物在大气中的组成分配率,主要取决于SO_2氧化为SO_4^(2-)的氧化速率。
A diffusion and chemical conversion model for atmospheric pollutants within the thermal internal boundary layer(TIBL) in coastal zone was developed, based on the processes of diffusion,transportation and chemical transformation of sulphur dioxide. The results indicated that a large part of secondary pollutants would be in the form of sulphate in atmosphere because of the chemical conversion effect. The distribution proportion of sulphur dioxide and its secondary pollutants mainly depended on the conversion rate of sulphur dioxide to sulphate.
