The high porosity of limestone presents another complication.

石灰石高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、率和形状一致性。

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

试图将此语不同理论模型相联证明了翻译边界率。

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

砂岩、石灰岩或玄武岩率很高，它们体积中高达40%部分实际上是空。

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

但石灰岩本身形成特性，即水、空气和分解物质产生气体，意味着石灰岩本身往往具有很高率。

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率--从结构中 " 切出 " 部分，让空气流过，并在建筑体周围流动。
