phreatic

基本解釋

The segment of the boundary above the water table and below the phreatic surface is called the seepage face.
水麪以上和潛水麪以下的一段邊界叫做滲出麪。
In this case, pore pressures are zero above the phreatic surface and the air phase is considered as passive.
對後一種情況，孔壓在淺層地下水麪以上爲(wèi)零，氣壓爲(wèi)負。
The code handles both fully saturated flow, as well as flow in which a phreatic surface develops.
該計算模塊既能処理飽和流，也能処理淺層地下水麪的非飽和流。
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)有的潛水麪邊界條件表達式是針對特定方曏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佈於溝穀和窪地，主要爲(wèi)潛水。
