| 摘 要： | 利用欧拉型区域硫沉降模式对污染源、干沉降和气相化学等物理化学过程在酸沉降中的作用进行了数值分析。结果表明:排放源的强度和高度影响着污染物的分布和输送，其影响是非线性的。在区域酸沉降模式中，干沉降速度和气相化学转化率简单地取为常数对SO#-2]及SO#+2-]#-4]浓度分布引起的误差是不可忽视的。

| Abstract: | The roles of source, dry deposition process and gas-chemistry in regional sulfur deposition are discussed by using a Regional Eulerian Sulfur Deposition Model Two numerical tests indicate that the strength and height of sources affect the distribution and transport flux and source-receptor relationships are nonlinear The results of another two tests show that the discrepancies between the concentration of SO 2 by using gas chemistry and dry deposition model and that with the constant gas oxidation rate and dry deposition velocity cannot be neglected |
