This pull is aided by a fundamental property of water called capillary action.

这种拉力还得到水的一种基本特征——毛细作用的帮助。

The pseudotracheae secrete enzyme-filled saliva and soak up fluids and dissolved foods by capillary action.

拟气管通过毛细管作用来分泌充满酶的唾液渗入它们的食物。

To accomplish this herculean task, the xylem relies on three forces: transpiration, capillary action, and root pressure.

要完成这样艰巨的任务，木质要依赖于三种力量：蒸腾作用，毛细作用和根压。

This is called capillary action and it's what allows water to climb tree roots and nutrients to flow around our body.

这就是所谓的毛细作用，这让水能够爬上树根、让营养物质在我们体内流动。

In fact, without the limitations of gravity on capillary action, directing liquids through these micro-structures could be extremely efficient.

事实上， 如果没有重力对毛细管作用的限制，引导液体通过这些微结构可能会非常有效。

He theorized that capillary action, the attraction between liquids and surfaces that pulls water through thin tubes, might keep the water cycling around the bowl.

他推测，毛细作用，即液体和表面之间的吸引力，将水通过细管，可能会保持水在碗周围循环。

The same process, called capillary action, allows plants to move water from deep below the ground to nourish the leaves and branches that grow in the sunshine.

同样的过程，被称为毛细作用，可以让植物把水从地下深处输送到阳光下生长的叶子和树枝上。

But if the capillary action is strong enough to overcome gravity and draw the water up, it would also prevent it from falling back into the bowl.

但是如果毛细作用足够强大，可以克服重力，把水吸上来，它也可以防止水落回碗里。

If the pen was turned upside down the capillary action and the surface tension of the ink would stop it from falling out the back of the pen.

如果把笔倒过来，毛细作用和墨水的表面张力会阻止墨水从笔的背面掉出来。

Trees use capillary action to draw water up from the roots in tiny tubes – a process that depends on the way water molecules stick to themselves and their surroundings due to surface tension.

树木利用毛细管作用将水从细管中的根部吸上来——这一过程取决于水分子由于表面张力而粘附在自身及其周围环境的方式。
