【摘要】 本文用数值解扩散方程的方法模拟了长沙市SO₂的浓度分布,并比较了两种扩散系数模型的模拟结果,认为作者曾经给出的扩散系数较取扩散系数为粘性系数时为好。最后提出了一种评价、比较模式的方法更多还原

【Abstract】 In this paper, the distribution of sulfur dioxide concentrations in Changsha City by solving numerically the diffusion equation is modeled. Compared the observed data with the computed results under two different diffusivities, it is found that my diffusion coefficient is better than the viscosity. Finally, a method of verification of model is also proposed.更多还原
