They're formed when ultraviolet light interacts with ethane you see.

它们是由于紫外线对乙的作用形成的，你看。

The infrastructure to turn that ethane into plastic, has expanded.

将乙转化为塑料的基础设施已经扩大。

Their liquid is not water but ethane and methane.

它们的液体不是水， 而是乙和甲。

It has lakes and seas of liquid methane and ethane, instead of water.

它有液态甲和乙的湖泊和海洋，而不是水。

Sometimes, a hexane can look like a pentane with an ethane sticking off of it.

有，看起来像戊， 上面粘着乙。

This is ethane, C2H6. Another gas, and it's mostly used in the production of plastics.

是乙，C2H6。 另一种气体， 主要用于塑料生。

It is so cold, though, that its liquid hydrocarbons, methane and ethane, that you would use for fuel here on Earth.

不过它非常冷，些都是液态烃，甲和乙，在地球上被用作燃料的液体。

So has investment in petrochemical plants that turn ethane into plastic.

对将乙转化为塑料的石化工厂的投资也是如此。

The availability of cheap ethane from the fracking boom, all across the country is driving this build-out.

- 全国各地水力压裂热潮中廉价乙的供应正在推动种扩建。

And at Titan, there are also exotic lakes and seas of liquid methane and ethane on the surface.

在土卫六上，地表也有奇异的液态甲和乙湖泊和海洋。

Once ethane is collected from fracking, it's sent to a cracker plant.

一旦从水力压裂中收集到乙，它就会被送到裂解厂。

And then the existence of the facilities sort of as a pull factor, drives the production of more ethane.

然后设施的存在有点像拉动因素，推动了更多乙的生。

Cracking ethane into ethylene also carries a huge carbon footprint.

将乙裂解成乙烯也会生巨大的碳足迹。

And U.S ethane now supplies 10% of European ethylene production.

美国乙现在供应欧洲乙烯量的 10%。

Despite the health impacts and the toll on the environment ethane and plastic production is big business.

- 尽管乙和塑料生对健康有影响，对环境也有影响，但仍是一项大生意。

The reason you'd have such a hard time keeping your head above the surface is due to the liquid methane and ethane found in Titan's lakes.

你很难将头保持在水面之上的原因是泰坦湖中发现了液态甲和乙。

Ethane cracker plastic production plant, for example, in Scotland, that was down to 40% capacity, because there wasn't enough ethane in Europe to run it.

- 例如，苏格兰的乙裂解塑料生厂的能下降到 40%，因为欧洲没有足够的乙来运行它。

According to one report the carbon emissions from the cracking of ethane and an alternative ingredient called naphtha were equivalent to 52 coal-fired power plants in 2015.

根据一份报告，2015 年乙和一种称为石脑油的替代成分裂解生的碳排放量相当于 52 座燃煤电厂的排放量。

So an ethane cracker is an absolutely enormous facility that uses a tremendous amount of energy to it's called crack the ethane molecules into ethylene, and then turn them into these tiny little plastic pellets.

- 所以乙裂解器是一个绝对巨大的设施，它使用大量的能量来将乙分子裂解成乙烯，然后将它们变成些微小的塑料颗粒。
