| Abstract: | Taking the chemical analysis results of the 4 water samples as the examples, the authors calculated and compared the changes of pH values,the saturation indices of calcite,and the equilibrium distribution of species caused by the dissolution or the precipitation of CaCO3 under the conditions of the open and closed systems in this paper . On the basis of the above comparison, the authors discussed the dissolution and precipitation of CaCo3 under natural conditions. |
