The high porosity of limestone presents another complication.

高孔隙率带来了另一个复杂问题。

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、孔隙率和形状一致性。

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联证明了翻译边界孔隙率。

Sandstone, limestone or basalt are so porous that up to 40 percent of their volume is actually empty  space.

砂岩、岩或玄武岩孔隙率很高，它们体积中高达40%部分实际上是空隙。

But the very nature of limestone's formation, water, air, and decomposing matter producing gas, means that limestone itself tends to be quite porous.

但岩本身形成特性，即水、空气和分解物气体，意味着岩本身往往具有很高孔隙率。

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.

尽管孔隙率可能相同，但从一种岩或沉积物到另一种岩或沉积物，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孔隙率--从结构中 " 切出 " 部分，让空气流过，并在建筑体周围流动。
