The high porosity of limestone presents another complication.

石灰石的高孔隙率个复杂因素。

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，检每个烤饼的颜色、孔隙率和形状的致性。

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.

风对高层建筑的影响的个方法增加其孔隙率--从结构中 " 切出 " 部分，让空气流过，并在建筑体周围流动。
