2.
The parametric relationship between hydrogen ion concentration and several major pollutants such as sulphur dioxide,volatile organic compounds,ammonia and nitrogen oxides in the atmosphere as well as temperature,zenith angle and rainfall intensity was studied based on some simplified assumptions of the Acid Rain Model in the physical precipitation.
对酸雨模式中降雨的物理过程进行了简化假设，在此基础上研究了大气中影响降雨氢离子浓度的几种主要污染物（ＳＯ２ ，ＶＯＣｓ ，ＮＨ３ ，ＮＯｘ） 及温度、天顶角、雨强等因素同降雨氢离子浓度的参数关系。
6) pH concentration control
氢离子浓度控制
补充资料：氢离子浓度指数(hydrogenionconcentrationexponent)
【氢离子浓度指数】(hydrogenionconcentrationexponent)简称“`pH`”。表示氢离子活度的一种方法。它是水溶液中氢离子活度的常用对数的负值，即`pH=-loga_(H^ )`。在稀溶液中，活度基本上等于浓度，于是可定义为`pH=-log[H^ ]`，`[H^ ]`以摩/升为单位。`pH`值的应用范围，通常在1-13之间。25℃时中性溶液的`pH`等于7，即`[H^ ]=10^(-7)`。`pH`值大于7时，即
