| 摘 要： | 昆明大环境中ＳＯ２ 和ＮＯｘ 的浓度变化具有明显的周期性（ 周期为１ 年） 和同步性， 冬季相对较高， 春、秋、夏季相对较低。这种变化主要受静风频率变化的影响， ＳＯ２ 和ＮＯｘ 与静风频率之间存在十分明显的正相关性。

| Abstract: | The density variation of SO 2 and NOx in air of Kunming is obviously periodic(one year a period)and simultaneous.It is high in winter while relatively low in spring,summer and autumn.This variation is strongly effected by still wind frequency which has a positive correlation with SO 2 and NO x |
