The high porosity of limestone presents another complication.

石灰石高孔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，检每一个颜色、孔隙率和形状一致性。

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。
