摘　　要：该文讨论了１９９１年８月下旬至１１月上旬在浙江临安大气污染本底站（属ＷＭＯ）所监测的微量气体ＳＯ＿２、ＮＯ＿２和Ｏ＿３浓度分布特征，微量气体化学转化过程对气溶胶浓度的影响，同时还讨论了空气质点轨迹特征和风向对上述过程的影响．结果表明：临安站微量气体浓度在一定条件下有明显的日变化，而且这种变化影响到气溶胶浓度的分布．The distribution characteristics of trace gases such as SO_2,NO_ and O_3,observed atLin’an background station in the period from the last. 10 days of August to the first 10days of November,1991,and the impact of the chemical transfering of these gases on theaerosol concentrations are investigated in the paper.The impact of air parceI trajectoriesand wind directions on the transfer process is also discussed.The results show that theconcentrations of trace gases at this station are in existence of a remarkable diurnalvariation under certain conditions,and the variation has an effect on the distributions ofaerosol concentrations.
