摘　　要：该文找出了影响云水ｐＨ值的主要因素，用统计分析的方法得到它们与云水ｐＨ值之间的简单的函数关系。通过参数化研究发现，在一定的变量取值范围内，模式模拟的结果与用函数关系式得到的结果能很好地对应起来，相关系数为０９４。该文参数化所考虑的变量为：气相Ｈ２Ｏ２，Ｏ３，ＳＯ２与ＮＨ３的浓度，液相Ｆｅ３＋与Ｍｎ２＋的浓度，水的含量及温度。In this study,the main factors which influence pH of cloud were found,and their simplified functional connection was got by using statistical analysis.The results of model simulation agree well with the calculated results from formulate within the limits permitted of variable.The coefficient is 0.94,and the concentration of gas phase H 2O 2,O 3,SO 2 and NH 3,liquid phase Fe 3+ and Mn 2+ ,H 2O and temperature were taken into consideration when parameterization was made in this study.
