常見例句The segment of the boundary above the water table and below the phreatic surface is called the seepage face. 水面以上和潛水面以下的一段邊界叫做滲出面。In this case, pore pressures are zero above the phreatic surface and the air phase is considered as passive. 對后一種情況,孔壓在淺層地下水面以上為零,氣壓為負(fù)。The code handles both fully saturated flow, as well as flow in which a phreatic surface develops. 該計算模塊既能處理飽和流,也能處理淺層地下水面的非飽和流。In the seepage theory, the current expression of boundary condition on phreatic surface is aimed at a kind of seepage. 滲流理論中現(xiàn)有的潛水面邊界條件表達(dá)式是針對特定方向的一類潛水滲流問題而給出的。The pore-space water in loosening rocks mainly distributed in ravine and depression, is mainly phreatic water. 松散巖類孔隙水主要分布于溝谷和洼地,主要為潛水。The variation characteristics of shallow confined groundwater are similar with phreatic water. 淺層承壓水含水組的地下水質(zhì)變化特征和潛水基本一致。 返回 phreatic
