采用水相形态计算、pH计算和CaCO 3溶解度（沉淀度）计算方法，研究了CaCO 3在天然沃茨中的混合腐蚀。分别在两种不饱和（含CaCO 3）溶液、两种过饱和溶液以及一种不饱和溶液和一种过饱和溶液之间进行混合。结果表明，混合腐蚀可分为两个不同的层次：严格意义上的混合腐蚀和广义上的混合腐蚀。当发生混合腐蚀时，一种端元溶液中HCO 3-浓度通常高于另一种端元溶液，
The methods of aqueous speciation calculation, pH calculation and the solubility (precipitability) calculation of CaCO3 were used to study the mixing corrosion of CaCO3 in natural waters. Mixing processes were done between two unsaturated (with CaCO3) solutions, two oversaturated solutions and between an unsaturated solution and an oversaturated solution, respectively. Results show that the mixing corrosion can be divided into two different levels: mixing corrosion in strict sense and mixing corrosion in broad sense. When mixing corrosion occurs, the HCO3- concentration in one end member solution is usually higher than that in the other solution, and the Ca2
