Beneath this active layer is a second layer called "permafrost", which is frozen all year around, and is impermeable to water.(在這一活躍層下面，是被稱為“多年凍土”的第二層，終年凍結，不透水。)

Impermeable rocks are desirable sealing rocks or cap rocks for reservoirs because hydrocarbons cannot pass through them readily.(不滲透的巖石對于儲層是期望的封隔或蓋層巖石，因為油氣不能輕易透過它們。)

Shale has a high porosity, but its pores are small and disconnected, so it is relatively impermeable.(頁巖有高孔隙度，但其孔隙既小而又不連通，所以它是相對不滲透的。)

An oil field consists of a reservoir in a shape that will trap hydrocarbons and that is covered by an impermeable or sealing rock.(一個油田由形態上會圈閉油氣、并被不滲透的或封閉巖石所覆蓋的儲集層組成。)

The accumulation of oil is governed by lateral changes from permeable to impermeable facies.(石油的儲集是受從滲透到不滲透的巖相橫向變化控制的。)

Clothing that is impermeable to water prevents the evaporation of sweat from the skin.(穿著不透水的衣服會阻礙體表汗液的蒸發。)

The impermeable ability of EC capsule bodies was gradually enhanced with the increase of viscosity grade of EC and concentration of EC solution.(隨著制備膠囊體的EC粘度級別的增加和EC溶液濃度的增大，制得的EC膠囊體的非滲透能力逐漸增大。)

The gourd has been used as a container since the earliest times, because of its naturally impermeable skin.(該葫蘆被用作一個容器，因為最早的時候，由于其自然滲透皮膚。)

It is observed that the crack impermeable model can be used under some condition.(結果表明，裂縫不可滲透的邊界模型在一定條件下可以合理使用。)

Yet the methods of culturing and studying human cells have traditionally been carried out in two dimensions on flat impermeable surfaces.(然而傳統的人類細胞培養與研究是在不透水的二維平面上進行的。)
