The porosity gradient of porous aluminium is mostly affected not only by the spontaneous stacking density of granules, but also by the infiltration pressure gradient and solidification sequence.
多孔铝合金的孔隙率梯度主要是由渗流驱动压力梯度与凝固顺序所决定，而颗粒的自然堆积密度影响相对较小。

The adsorption of pigments, soluble vitamins and oils by the micro porous starch was significantly higher than that by the original starch granules.
微孔淀粉对色素、水溶性维生素、油脂的吸附能力远远高于原淀粉。
