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

因此，不管沉物是疏松还是坚，它们中一定有空间。大部分结晶体岩石都非常坚硬，但也有例外，最常见就是玄武岩，它是一种火山熔岩，经常充满了微小气泡，从而变得十分多。

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

这些是多分子网络，空气可以通过它们循环。它们多性使它们具有很大表面。

The high porosity of limestone presents another complication.

石灰石高隙率是另一个复杂因素。

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

冷却后，助手们扫描烤饼，检查每一个烤饼颜色、隙率和形状一致性。

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

试图将此术语与不同理论模型相关联证明了翻译边界隙率。

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，但从一种岩石或沉物到另一种岩石或沉物，这两种水相对量差异很大。

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影响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。
