According to the coal sample's pore fractal laws, the porosity of coal is divided into three categories: infiltrationpore, diffusion pore and adsorption pore.
这三类孔同时也对应了瓦斯等气体在煤中的不同的运移状态。

Based on these, the technique factors that influence the foam aluminum pore structure in the infiltration casting were studied.
在此基础上，对渗流铸造法中影响泡沫铝合金孔结构的其他工艺因素也进行了研究。

The infiltration and deposition of alkali salts in the form of vapor or liquid will gradually result in a complete filling of the apparent pore and brick densification.
