Exhaust gases escape through ports in the cylinder walls.

而废气通过汽缸壁的接口出。

But industrial gas emissions are warming the planet.

工业废气是全球变暖的主要原因。

There is no exhaust gas. The only byproducts are electricity heat and water.

没有废气。唯一的副产品是电、热和水。

Two other techniques, called gasification and oxy-combustion, work by reacting coal with pure oxygen rather than air, and thus produce exhausts that require little treatment before burial.

其他两种叫做气化和烧的技术，用纯气而不是空气烧煤，这样产生的废气在掩埋之前几乎不用处理。

When ships power their way through the ocean, they pump exhaust into the atmosphere, just as cars do.

轮船开动油门在海上行驶，也会向大气中废气，与汽车一样。

This is because there is not enough wind to blow away all of the cars' exhaust fumes and other smoke from factories.

这是因为没有足够的风吹散所有汽车的废气，还有其它工厂的烟。

It's this idea that being able to move ten times faster than, you know, a car and doing that for a fraction of the emissions.

它的理念是，能够以比汽车快十倍的速度行驶，而的废气却很少。

Although there are many types of emissions, such as from factories, these zones predominantly target exhaust fumes from vehicles, poisonous gases called nitrogen dioxide.

尽的类型有很多，比如来自工厂，但这些区域主要针对车辆的废气，一种叫做二化氮的有毒气体。

Soil tilling releases carbon dioxide, and delivery vehicles emit exhaust.

土壤耕作会释二化碳，送货车辆会废气。

It causes fumes in the city which cause us in turn to get diseases, maybe heart diseases, which are not good for our health.

它在城市里废气，进而导致我们患上疾病，可能是心脏病，对我们的健康不利。

But it's also saving the fumes for the planet.

但这也为地球节省了废气。

When you hear about pollution, you might picture exhaust fumes, littering, or oil spills.

当你听到”污染”一词时，也许想到的是废气、废物或者石油泄漏。

So the hot aisle where it expels all the hot air and the cold aisle which actually has the cold air go through the actual computers themselves and the fans that actually expel the exhaust.

它出所有热空气的热通道和实际有冷空气的冷通道通过实际的计算机本身和实际出废气的风扇。

I also saw what it's like when you take away the diesel fumes and the black smoke that spew from today's freighters and ports.

此外，我还看到了没有了当今货船和港口喷出的柴油废气和黑烟的场景。

And it creates a waste product, oxygen gas.

它会产生废气，即气。

The waste gas traps heat in the atmosphere, causing the planet to warm.

废气将热量滞留在大气中，导致地球变暖。

The exhaust from our cars pollutes the air and causes asthma in children.

我们汽车的废气会污染空气，使幼童罹患气喘。

Nuclear energy is efficient and doesn't produce carbon gases as a waste product.

核能是高效的，不会产生作为碳废气。

Trees can also reduce the amount of exhaust gases and particles in the air, with some studies claiming that they help reduce local concentrations of nitrogen oxide by up to 57%.

树木还可以减少废气和空气中颗粒的数量，一些研究声称，它们有助于将当地的氮化物浓度降低高达 57%。

They have to pay for fuel, they have to pay for whatever burns it, but once it is an exhaust gas they can just let it go.

他们必须为料付费，他们必须为任何烧它的东西付费，但一旦它成为废气，他们就可以把它随手掉。
