| 摘 要： | 文章在计算水溶液化学组份平衡分布及其ｐＨ值的基础上，分析和讨论了封闭系统中ＣａＣＯ３溶解或沉淀所引起的水化学后果，并依据计算数据和借助作图的办法得出了如下结论，即ＣａＣＯ３溶解会使水溶液ｐＨ值增大，Ｈ２ＣＯ３含量减少；相反，ＣａＣＯ３沉淀会使水溶液ｐＨ值减小，Ｈ２ＣＯ３含量增多。

| Abstract: | Based on a calculating of a equilibrium distribution of species and pH values for natural waters,this paper analysed and discussed the water-chemical consegunces caused by the dissolution or precipitation of CaCO3 in a closed systems of natural water, and on basis of calculated data and by means of map-making method was achieved a following conclusion i. g. with the dissolution of CaCO3, the pH value of the water will increase, the concentratior of H2CO3 will decrease, whereas with the precipitation of CaCO3, the pH value of the water will decrease, and the concentration of H2CO3 will inrease. |

| Keywords: | water-solution closed system dissolution or precipitation of CaCO3 pH value saturaion index |
