Exhaust gases escape through ports in the cylinder walls.

而废气通过汽缸壁接口排出。

But industrial gas emissions are warming the planet.

工业废气排放是全球变暖主。

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

没有废气。唯一副产品是电、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.

其他两种叫做气和富氧燃烧技术，用纯氧气而不是空气烧煤，这样产生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，也会向大气中排放废气，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.

这是为没有足够风吹散所有汽车废气，还有其它工厂排放烟。

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.

它理念是，能够以比汽车快十倍速度行驶，而排放废气却很少。

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

尽管排放类型有很多，比如来自工厂，但这些区域主针对车辆排放废气，一种叫做二氧有毒气体。

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

土壤耕作会释放二氧碳，送货车辆会排放废气。

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

它在城市里排放废气，进而导致我们患上疾病，可能是心脏病，对我们健康不利。

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.

它排出所有热空气热通道和实际有冷空气冷通道通过实际计算机本身和实际排出废气风扇。

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柴油废气和黑烟场景。

And it creates a waste product, oxygen gas.

它会产生废气，即氧气。

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.

我们汽车排放废气会污染空气，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，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数量，一些研究声称，它们有助于将当地氧物浓度降低高达 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.

他们必须为燃料付费，他们必须为任何燃烧它东西付费，但一旦它成为废气，他们就可以把它随手放掉。
