The huge pressure difference creates a vacuum capable of shooting anything up to 1,000 pounds out into the sky.

巨大的气压差产生的吸力，能把任何重达一千磅的东西吸进空中。

This pressure difference results in the upwards force of lift.

这种压力差导致向上的升力。

But a plane experiences a pressure difference every time it climbs to cruising altitude.

但是飞机每次爬升到巡航高度时都会经历压力差。

The faster the plane travels, the greater the pressure difference, and the greater that force.

飞机飞得越快，压力差就越大，力也就越大。

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 pressure difference caused massive systematic failures, and pilots began to lose  control of the plane.

压力差导致大量系统故障，飞行员开始失去对飞机的控制。

This pressure difference is important, because later, we will see that blood flows from high to low pressure.

这个压力差很重要，因为稍后，我们将看到血液从高压流向低压。

And, while experts agree that the pressure difference generates lift, their explanations for how can vary.

而且， 虽然专家们同意压力差会产生升力，但他们对如何产生升力的解释各不相同。

Corners and flat walls are weak points so the habitats will have rounded and smooth shapes to handle the stress of great pressure differences between the interior and exterior.

角落和平坦的墙壁较为薄弱，因此栖息地将具有圆状和平滑的形状来应付内部和外部之间的巨大压力差。

Also this fluid leakage reduces the pressure difference that drives filtration of small molecules and electrolytes like sodium, and so the GFR actually goes down because of the leakage.

此外，这些液体泄漏减小了驱使小分子以及钠等电解质滤过的压力差，因此滤过率由于泄漏而下降。

In fact, a flat wing that's tilted upwards can also create lift— as long as the air bends around it, contributing to and reinforcing the pressure difference.

事实上， 向上倾斜的扁平机翼也可以产生升力——只要空气在它周围弯曲，有助于并加强压力差。

To protect its crew a submarine must therefore be able to keep the air inside at a relatively normal pressure, which then creates a massive pressure difference between the inside and outside that its hull must resist.

因此，为了保护船员，潜艇必须能够将内部空气保持在相对正常的压力下，因此潜艇必须能够抗住内外部产生的巨大压力差。

While there would probably be other things to take into account, like a change in diet and pressure differences, breathing underwater is one of the biggest obstacles we'd have to overcome to engineer ourselves to live underwater.

虽然可能还有其他因素需要考虑，比如饮食和压力差异的变化，但水下呼吸是我们设计自己在水下生活所必须克服的最大障碍之一。
