That porous material that was the bone got filled in with little spheres, opal, basically.

骨头的多孔材料被填充了小球体，基本上是蛋白石。

The reason for this is that, like many other porous materials, fresh snow is very good at absorbing sound.

原因是，像许多其他的多孔材料，新鲜的雪很容易吸收声音。

Then the kinda-liquid-kinda-gas can drift out of the solid molecular structure, and be replaced by air, so you have a porous, lightweight material that retains its shape.

然后，这种似液体又似气体的物质可以从坚固的分子结构中漂移出来，被空气所取代，这样你便得到有气孔的还保持原始形状的极轻材料。

They also use adsorption filtration, where a porous material called activated carbon strains the water to remove contaminants and chemical byproducts.

他们还使用吸附过滤，一种叫做活性炭的多孔材料过滤水以去除污染物和化学副产品。

We've designed it in a way where there's holes so that this can get internally filled with kind of a porous material that feels like the inside of bone marrow.

文森特：我们以一种有孔的方式设计它，这样它就可以在内部填充一种感觉像骨髓内部的多孔材料。
