The observational and calculated results are well matched. The calculated mean diameter, mean square-root diameter, mean cube -root diameter and liquid water content are all well matched with the observational results; In the paper two examples have been analyzed by using the seeding region data and the possible affecting region data in leeward region. It is found that F-100, 2dc, and 2dp's particle concentrations increase in leeward region, but rising extent is different, which is likely to be due to difference of seeding effect time.

拟合值和观测值吻合的较好，计算出的平均直径、均方根直径、均立方根直径和粒子浓度与观测值也比较吻合；本文对两组个例的催化影响区域及可能采集到相应值的下风方区域进行了分析，催化下风向影响区的F-100、2DC、2DP的粒子浓度比背景值都有所增加，但是增加的幅度不同，应该是催化响应时间的原因。
