The proportion of empty space in a rock is known as its porosity.

因此，不管沉积物是疏松还是坚固，它中一定有空间。大部分结晶体岩石都非常坚硬，但也有例外，最常见的就是玄武岩，它是一种固化的火山熔岩，常充满了微小气泡，从而变得十分。

These are porous molecular networks through which air can circulate. Their porosity gives them a huge surface area.

这些是的分子网络，空气可以通过它循环。它的性使它具有很大的表面积。

The high porosity of limestone presents another complication.

石灰石的高隙率带来了另一个复杂问题。

So bookmark this concept of pressure and pore space and porosity.

所以，请记住压力、隙空间和隙度的概念。

After being cooled, assistants scan the crumpets, inspecting each one for their color, porosity, and consistency in shape.

冷却后，助手扫描烤饼，检查每一个烤饼的颜色、隙率和形状的一致性。

Attempting to associate this terminology with distinct theoretical models demonstrates the porosity of translation boundaries .

试图将此术语与不同的理论模型相关联证明了翻译边界的隙率。

And so it helps, I think, for us to understand that there is a porosity between human-controlled landscapes and non-human-controlled landscapes.

因此，我认为，这有助于我理解人类控制区域与非人类控制区域之间存在着渗透性。

The relative amount of these two kinds of water varies greatly from one kind of rock or sediment to another, even though their porosities may be the same.

尽管隙率可能相同，但从一种岩石或沉积物到另一种岩石或沉积物，这两种水的相对量差异很大。

Another way to reduce the impact of high winds on tall buildings is to increase their porosity - " cutting out" parts out of the structure and allowing air to flow through, as well as around the building mass.

减少大风对高层建筑的影响的另一个方法是增加其隙率--从结构中 " 切出 " 部分，让空气流过，并在建筑体周围流动。
