The segment of the boundary above the water table and below the phreatic surface is called the seepage face.

水面以上和潜水面以下的一段边界叫做渗出面。

Therefore whether the approach to locate the phreatic surface is appropriate or not is essential to the accuracy of the stability analysis.

因此确定浸润面位置的方法正确与否，对稳定性分析的结果是否准确至关重要。

Volcanic explosion craters such as Dallol form during phreatic eruptions—where rising magma comes into contact with water beneath the surface of the Earth, causing a steam explosion.

像宽干谷这样爆裂的火山口形成于蒸汽喷发的过程中，在那里，上升的岩浆与地表下的水接触形成了蒸汽喷发。
