摘要
本文提出了不同二氧化碳分压（Ｐｃｏ_２）条件下水溶液的ｐＨ值及溶液中化学组分平衡分布的计算方法，并根据两个水样的水质分析结果，建立起了水样的水化学模型，计算了这两个水样的ｐＨ值、Ｈ_２ＣＯ_３、和的含量以及水溶液相对方解石的饱和指标随Ｐｃｏ_２的变化关系，并对计算结果进行了讨论。
In this paper,the authors have developed a method for calculating pH values and equilib- rium distribution of species in natural water under the conditions of different partial pressureof carbon dioxide(Pco_2).The hydrochemical model was set up according to the chemical anal-ysis results of two water samples.The pH values,concentrations of H_2CO_3、HCO_3,and as well as saturation index of calcite were calctilated for the two samples under differentPco_2. In the end,the authors have givena disctission on the calculated results.
