1) natural groundwater
天然地下水
1.
Mixing were made for three groups of natural groundwater,one is the mixing between unsaturated(with CaCO3) water,the second group is the mixing between supersaturated water,and the last group is the mixing of unsaturated water with supersaturated water.
以水溶液平衡化学模型为基础,使用实际地下水样的水质分析结果,对相对CaCO3处于未饱和、过饱和状态地下水的混合进行了模拟计算,发现两种天然地下水的混合,不但可以发生混合溶蚀作用,而且还可发生混合沉淀作用。
