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

它们由于紫外线对烷的用形成的，你看。

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

将烷转化为塑的基础设施已经扩大。

Their liquid is not water but ethane and methane.

它们的液体不水， 烷和甲烷。

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

它有液态甲烷和烷的湖泊和海洋，不水。

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

有时，己烷看起来像戊烷， 上面粘着烷。

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

烷，C2H6。 另一种气体， 主要用于塑生产。

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，些都液态烃，甲烷和烷，在地球上被用的液体。

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

对将烷转化为塑的石化工厂的投资也如此。

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烷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烷和烷湖泊和海洋。

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

一旦从水力压裂中收集到烷，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，推动了更多烷的生产。

Cracking ethane into ethylene also carries a huge carbon footprint.

将烷裂解成烯也会产生巨大的碳足迹。

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

美国烷现在供应欧洲烯产量的 10%。

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

- 尽管烷和塑生产对健康有影响，对环境也有影响，但仍一项大生意。

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泰坦湖中发现了液态甲烷和烷。

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，苏格兰的烷裂解塑生产厂的产能下降到 40%，因为欧洲没有足够的烷来运行它。

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 年烷和一种称为石脑油的替代成分裂解产生的碳排放量相当于 52 座煤电厂的排放量。

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.

- 所以烷裂解器一个绝对巨大的设施，它使用大量的能量来将烷分子裂解成烯，然后将它们变成些微小的塑颗粒。
