The Earth is full of empty space.

整个球也有无数孔隙。

The bigger the pores, the easier the gas can spread.

孔隙越大，气体就越容易扩散。

The incense smoke rises from the holes, eventually, the hill censer becomes a dreamland in miniature.

香烟从孔隙中升起，最终，博山炉便造了境。

He speculated that the jet becomes unstable inside that gap, setting up an acoustic feedback loop within the gap.

他怀疑蒸汽经过盖子孔隙时变得，是在间隙内引起了声学回路。

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石了，意即，我们可以在原本没有孔隙空间的方制造出孔隙空间来。

There are grains and there are pores between those grains.

有颗粒，颗粒之间有孔隙。

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.

石灰石的高孔隙率是另一个复杂因素。

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

相反，蛋壳有非常小的孔隙，可以让氧气进入。

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

糖类进入真菌后，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.

当无粘性土时，水会填充每个颗粒之间的孔隙空间。

Consolidated (or cemented) sediments, too, contain millions of minute water-holding pores.

固结（或胶结）沉积物也含有数百万个微小的保水孔隙。

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。

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进入叶肉组织。

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

随着太阳断对石墨进行加热，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。

The necessary space is there, however, in many forms.

下水是指渗入到下并将所有岩石孔隙填满的水。到现在为止，大气水是最丰富的下水资源，是下水在水循环中的一个环节。普通的大气水会从表、降水以及湖泊河流侵入到下。在再次冒出表之前，这些下水有时会长时间留在下。最初让人觉得难以置信的是，在我们脚下“坚实的”土中竟然有足够的空间能储存这么些水。

Attempting to associate this terminology with distinct theoretical models demonstrates the porosity of translation boundaries .

试图将此术语与同的理论模型相关联证明了翻译边界的孔隙率。

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、孔隙率形状的一致性。

Leaves provide food for the plant through a process called photosynthesis and breathe in air through pores called stomata.

叶子通过称为光合作用的过程为植物提供食物, 并通过称为气孔的孔隙吸入空气。

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。
