1.
Using the definition and calculation formula of distribution coefficients, the deduction of the hydrogen ion concentration in solutions will be simple,clear and exact.
利用分布系数的定义和计算公式推导溶液的氢离子浓度,该方法思路简单、明了、求解准确。
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。
补充资料：血氢离子浓度
血氢离子浓度
指血浆的酸碱度，以pH表示。正常人血浆pH值约在7.35～ 7.45之间。人体所能耐受的pH值最大变动范围约为6.9～7.8。血浆pH值之所以能保持相对恒定，与肺、肾功能和血液缓冲系统的作用密切有关。酸中毒时pH降低，碱中毒时pH增高。
