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，潛流和垂直流濕地植物都對水流流態(tài)有明顯影響，增大了水流傳輸路徑，延長(cháng)了水力停留時(shí)間。
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. 采用二級串聯(lián)潛流式人工濕地系統對太湖地區農村生活污水進(jìn)行了脫氮除磷的試驗研究。
With the sample of longitudinal motion equation, calculating hydrodynamic coefficients by the potential fluid theory is introduced. 并以其縱向運動(dòng)方程為例，詳細介紹了用勢流理論求解水動(dòng)力系數的方法。
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. 在線(xiàn)性有勢流的假定下，用特征函數展開(kāi)方法求出了內部和外部流場(chǎng)的解。
