| 摘 要： | 用差分方法求解三维大气平流扩散多源方程,模拟了本溪地区SO2浓度的时空分布。通过1999年1月19日的模拟结果与监测值对比表明:模拟结果比较准确地反映了SO2浓度的实际变化情况;由模拟计算可知,本溪地区SO2的污染很严重,且SO2浓度的时空分布有明显的日变化。10:00以前的浓度值比较大,10:00之后浓度值逐渐减小,到18:00左右浓度值又慢慢变大。

| Abstract: | The spatial-temporal distributions of SO_2 in Benxi region is simulated using the method of difference for solving the 3D equation of the atmospheric diffusion.The contrast of the simulated and observed values shows that the calculated result of modle basically reflect the real change of SO_2 concentration.On the basis of the calculated result,it is found that the pollution of SO_2 in Benxi is very severe,and the spatial-temporal distributions of SO_2 concentration appear obvious dayily change. The number of concentration of SO_(2)is higher before 10:00,and after 10:00,the number of concentration gradually became low,the number of concentration of SO_(2)became slowly high around 18:00. |
