多孔性

The porousness of snow makes it absorb sound.

雪花的多孔使得它能吸收声音。

Porosity can be caused by gases coming out of solution during cooling and becoming trapped between dentrite arms as tiny voids.

过程中，溶液中的气体逸出造成多孔，或被截留晶体枝杈之间形成微小气孔。

And as all have nuclear polyporous dvysocket making cloth cover the infiltration of water soluble Binder, so the fabric adhesive well, easy to layers.

布料纸张一样都具有多孔，容易使核糊布料封面所用的水溶结剂渗入，因此布料的好，容易裱合。
