And we can also fracture rock now, which means that we can create pore space where pore space does not exist naturally.

现在我们还可以压裂岩，意即，我们可以在原本没有孔隙空间的地方制造出孔隙空间来。

But those pores also allow  for the evaporation of water.

但这些孔隙也允许水分蒸发。

The high porosity of limestone presents another complication.

灰的高孔隙率是另一个复杂因素。

These chemical reactions can rearrange the carbon atoms to form lots of tiny pores.

这些化学反应可以重新排列碳原子， 形成许多微小的孔隙。

Instead, an eggshell has very small pores that allow oxygen to come in.

相反，蛋壳有非常小的孔隙，可以让氧气入。

Once the sugars enter the fungus, they travel along the hyphae through pores between cells or through special hollow transporter hyphae.

入真菌后，它们通过细胞间的孔隙或特殊的中空转运体菌丝沿菌丝传播。

When a body of cohesionless soil is saturated, water fills the pore spaces between  each particle.

当无粘性土壤饱和时，水会填充每个颗粒之间的孔隙空间。

The nanotubes are so tiny that they squeezed through the leaf’s pores and into the mesophyll tissue.

纳米管非常小，以至于它们挤过叶子的孔隙并入叶肉组织。

The stowaway microbes embedded themselves deep within the pores of the speeding comet, sheltering themselves from the radiation of deep space.

这些“偷渡”的微生物将自己深藏在高速飞行的彗星孔隙中，以避免被太空中的辐射所伤。

As sun heats the graphite, it creates a pressure difference that pulls water up through the foam pores, like a sponge.

随着太阳不断对墨行加热，就会产生一个压力差，而后像挤海绵一样，水分从泡沫孔隙中被挤压出来。

After being cooled, assistants scan the crumpets, inspecting each one for their color, porosity, and consistency in shape.

冷却后，助手们扫描烤饼，检查每一个烤饼的颜色、孔隙率和形状的一致性。

Then, once these compounds build up enough, they form a sponge-like network that traps other metals from the seawater in the pores.

然后，一旦这些化合物积累得足够多，它们就会形成海绵状网络，将海水中的其他金属捕获在孔隙中。

Gradual increases in loading will only cause the water within the soil to flow  out, equalizing the pore water pressure.

负荷的逐渐增加只会导致土壤中的水流出，平衡孔隙水压力。

All this iron and manganese comes from seawater and also from liquids that squeeze out from pores in the sediments beneath the rocks.

所有这些铁和锰都来自海水，也有来自从岩下方沉积物孔隙中挤出的液体。

Every pore, every soil crumb is covered with mycelium and the mushrooms that emerged from that mycelium, that's what you see in the forest.

每一个孔隙、每一块土屑都布满菌丝体，而从菌丝体中长出来的蘑菇，就是你在森林里看到的东西。

It goes through this change that sort of makes the wood really resonant, because the resin in the wood crystallizes, opens up the pores for vibration.

这种温度变化让木质的音效很好，因为木材里的树脂会结晶，为震动发制造孔隙。Church beams教堂的横梁。
