It creates what's called supercritical water.

它创造了所谓的超临界水。

But when supercritical water encounters a PFAS molecule, supercritical water oxidation can break it down.

但是当超临界水遇到全氟辛烷磺酸分子时，超临界水氧化可以分解它。

That last bit is what makes supercritical water so special.

最后一点是超临界水如此特别的原因。

To start a fire with water, you need supercritical water.

用水生火，需要超临界水。

When water is in that supercritical state, it's both a liquid and a gas.

当水处于超临界状态时，是液体也是气体。

So treating contaminated water with supercritical water oxidation can make it safe to drink again!

所以用超临界水氧化处理污染水可以让它再次安全饮用！

If water is liquid, ice is solid, and steam is gas, supercritical water is the fourth option.

如果水是液体，冰是固体，蒸汽是气体的话，超临界水是第四种选择。

Like a gas, supercritical water can make its way through tiny gaps in solid objects.

像气体一样，超临界水可以通过固体物体的微小间隙。

This process is known as supercritical water oxidation.

这个过程超临界水氧化。

That means fires burn away organic waste in a very similar way to supercritical water.

这意味着火燃烧有机废物的方式与超临界水非常相似。

A substance that's not quite liquid or gas, known as supercritical fluid.

一种不是液体也不是气体的物质， 超临界流体。

In physics, there's a phenomenon known as supercritical assembly.

在物理学界 有个现象叫做超临界组成。

Then, they use extremely high temperatures and pressures to blur the line between the liquid and gas phases, creating a supercritical fluid.

然后，他们用极高的温度和压力来模糊液体和气体阶段的分界线，制造超临界液体。

When supercritical water encounters a molecule of waste, it breaks up the bonds between the atoms, letting them react with oxygen.

当超临界水遇到废物分子时，它会打破原子之间的键，让它们与氧气反应。

Supercritical water has the potential to burn all sorts of waste, and might get us over more than one hurdle on the way to clean drinking water.

超临界水有可以燃烧各种废物，并且可能会让我们在清洁饮用水的道路上跨越不止一个障碍。

So any large-scale application of supercritical water to clean up our PFAS crisis will need to make sure our climate crisis doesn't get any worse in the process.

因此，任何大规模应用超临界水来清理我们的全氟辛烷磺酸危机都需要确保我们的气候危机不会在这个过程中变得更糟。

While we do see tiny hotspots of fire in a supercritical water reaction, for the most part, the reaction burns organic material really cleanly, without flames.

虽然我们确实在超临界水反应中看到了微小的高温区域，但在大多数情况下，反应燃烧有机物质非常干净，而且没有火焰。

That means supercritical water could be used to send astronauts on longer and longer space voyages, like the ones that we'll need to get to Mars.

这意味着超临界水可以用来送宇航员进行越来越长的太空航行，比如说去火星的航行。
