| 摘 要： | 本文根据大气中NO_2形成HNO_3的主要化学反应求解带有化学反应的扩散方程而得到HNO_3生成量的空间分布。HNO_3气体形成后边扩散边被降水清洗带至地面。我们又求解了HNO_3气体的扩散方程,考虑降水清洗从而得到HNO_3被降水带至地面的湿沉降量,得到水平面上HNO_3在24h内的分布,可用来大致估计HNO_3污染程度及范围。

| Abstract: | According to the main chemical reaction by which the HNO3 is formed from NOx in the atmosphere,the NO2 diffusion equation involving the chemical reaction is solved to obtain the distribution of HNO3 vapor.The HNO3 vapor is scavenged and precipitated to the ground by rain at the same time of its diffusion.Then,the diffusion equation of HNO3 vapor is solved incorporating the washout of rain to obtain the distribution of precipitated HNO3 on the ground in the 24 hours,by which we can estimate the level and domain size of the pollution of HNO3 approximately. |
