Numerical Studies of Effects of Source,Dry Deposition and Gas-chemistry on Sulfur Deposition Process
污染源、干沉降和气相化学影响硫沉降的数值研究

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
