The development of subsurface flow in soil slope due to rainfall infiltration has been studied with numerical analysis. 摘要对降雨渗入坡面土壤所产生地下水流的进展过程进行了数值解析计算。
Using a linear complementarity formulation, a theory of the coupling between the subsurface and surface flow is proposed. 利用线性互补的概念，提出了一个结合地下水流和表面水流的理论。
Experiments of nitrogen and phosphorus removal from rural domestic wastewater in the Taihu Lake basin were carried out by the two-stage subsurface flow constructed wetland process. 采用二级串联潜流式人工湿地系统对太湖地区农村生活污水进行了脱氮除磷的试验研究。
In VFW, the influence of wetland plants on the water flow pattern is not observed before clogging, and after clogging HRT is extended by wetland plants. 在堵塞后，潜流和垂直流湿地植物都对水流流态有明显影响，增大了水流传输路径，延长了水力停留时间。
