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。
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。
With the sample of longitudinal motion equation, calculating hydrodynamic coefficients by the potential fluid theory is introduced. 并以其纵向运动方程为例，详细介绍了用势流理论求解水动力系数的方法。
Under the assumptions of linearized potential flow, the coupled problem of flow in the interior and exterior fluid regions is solved by an eingenfunction-expansion approach. 在线性有势流的假定下，用特征函数展开方法求出了内部和外部流场的解。
