| 摘 要： | 大气降水的化学组成特征是大气环境质量一种表征，分析各种阴阳离子的浓度为酸雨污染控制和提高空气质量提供理论依据。大气降水酸度决定于SO4^2-、NO^-3、C1^-、HCO3^-、NH4^＋、Ca^2＋、Na^＋、K^＋、Mg^2＋、H^＋等阴阳离子相对浓度，利用离子平衡分析、相关性、主成份因子以及聚类分析等数理统计的方法对这些离子浓度进行分析，从而可以确定地域大气降水的影响因素，为大气污染治理提供一些相关的理论依据。

| Abstract: | The chemical composition of atmospheric deposition is a characterization of atmospheric environmental quality. The concentration of various ions provides a theoretical basis for the control of the acid rain pollution and the improvement of air quality. The acidity of precipitation is decided to the relative concentration, such as SO4^2-, NO^-3, Cl^- , HCO3^-, NH4^＋, Ca^2＋ , Na^＋ , K^＋ , Mg^2＋, H^＋. Thereby ,the meteoric geographical factors can made sure by Calculating those？ Chemical ionization with Mathematical statistical methods ,which using the Ion balance analysis, Correlation analysis, the principal component factor, and Cluster Analysis ans so on. |
