Standard test method for water absorption , bulk density , apparent porosity , and apparent specific gravity of fired whiteware products 焙烧卫生陶瓷制品的吸水率松密度表观多孔性与表观比重的标准试验方法
Porosity can be caused by gases coming out of solution during cooling and becoming trapped between dentrite arms as tiny voids 在冷却过程中，溶液中的气体逸出造成多孔性，或被截留在晶体枝杈之间形成微小气孔。
A clear correlation between the granule porosity ( ealuated by x - ray tomography ) and the binder concentration was found for the mannitol granules 对于甘露醇颗粒，发现颗粒多孔性（用x -线断层摄影术测定）与黏合剂浓度间明显相关。
