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

它们是由于紫外线对作用形成，你看。

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，这些都是液态烃，甲，在地球上被用作燃料液体。

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

它有液态甲泊海洋，而不是水。

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

这是，C2H6。 另一种气体， 主要用于塑料生产。

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

有时，己看起来像戊， 上粘着。

Cracking ethane into ethylene also carries a huge carbon footprint.

将裂解成烯也会产生巨大碳足迹。

Their liquid is not water but ethane and methane.

它们液体不是水， 而是甲。

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

在土卫六上，地表也有奇异液态甲泊海洋。

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

对将转化为塑料石化工厂投资也是如此。

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供应正在推动这种扩建。

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

一旦从水力压裂中收集到，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.

然后设施存在有点像拉动因素，推动了更多生产。

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

美国现在供应欧洲烯产量 10%。

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

- 尽管塑料生产对健康有影响，对环境也有影响，但仍是一项大生意。

Titan has seas, rivers and lakes of ethane and methane as warm as the universe when it was 90 million years old.

土卫六拥有充满甲海洋、河流泊，其温度与 9000 万年前宇宙一样温暖。

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

将转化为塑料基础设施已经扩大。

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之上原因是泰坦中发现了液态甲。

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 年一种称为石脑油替代成分裂解产生碳排放量相当于 52 座燃煤电厂排放量。

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.

- 所以裂解器是一个绝对巨大设施，它使用大量能量来将分子裂解成烯，然后将它们变成这些微小塑料颗粒。

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，苏格兰裂解塑料生产厂产能下降到 40%，因为欧洲没有足够来运行它。
