Beneath this active layer is a second layer called "permafrost", which is frozen all year around, and is impermeable to water.(在这一活跃层下面，是被称为“多年冻土”的第二层，终年冻结，不透水。)
Impermeable rocks are desirable sealing rocks or cap rocks for reservoirs because hydrocarbons cannot pass through them readily.(不渗透的岩石对于储层是期望的封隔或盖层岩石，因为油气不能轻易透过它们。)
Shale has a high porosity, but its pores are small and disconnected, so it is relatively impermeable.(页岩有高孔隙度，但其孔隙既小而又不连通，所以它是相对不渗透的。)
An oil field consists of a reservoir in a shape that will trap hydrocarbons and that is covered by an impermeable or sealing rock.(一个油田由形态上会圈闭油气、并被不渗透的或封闭岩石所覆盖的储集层组成。)
The accumulation of oil is governed by lateral changes from permeable to impermeable facies.(石油的储集是受从渗透到不渗透的岩相横向变化控制的。)
Clothing that is impermeable to water prevents the evaporation of sweat from the skin.(穿着不透水的衣服会阻碍体表汗液的蒸发。)
The impermeable ability of EC capsule bodies was gradually enhanced with the increase of viscosity grade of EC and concentration of EC solution.(随着制备胶囊体的EC粘度级别的增加和EC溶液浓度的增大，制得的EC胶囊体的非渗透能力逐渐增大。)
The gourd has been used as a container since the earliest times, because of its naturally impermeable skin.(该葫芦被用作一个容器，因为最早的时候，由于其自然渗透皮肤。)
It is observed that the crack impermeable model can be used under some condition.(结果表明，裂缝不可渗透的边界模型在一定条件下可以合理使用。)
Yet the methods of culturing and studying human cells have traditionally been carried out in two dimensions on flat impermeable surfaces.(然而传统的人类细胞培养与研究是在不透水的二维平面上进行的。)
