Based on the grey system theory, a grey assessment model of groundwater quality is built by combining the method of grey relational grade analysis and the method of single factor contaminant index.

以灰色系统理论为基础，把灰色关联度分析方法和单因子污染指数法相结合，构造了一种适合于评价地下水质量的灰色模型。

The analysis includes the concentration ratio at the base of a GCL, advective and diffusive mass flux, and total accumulated contaminant mass through the liner per unit area.

从衬垫底部浓度比、对流和扩散通量、污染物累积运移量等方面，对污染物在GCL中的运移进行了计算。
