The cheapest option could be to use giant mid-air refuelling aircraft, such as the US air force's KC-10 Extender, filled with sulphur dioxide or hydrogen sulphide gas.
在夜晚，这架飞机不但检测臭氧、氮氧化物和其他气体的浓度，还测量了飞机下的光照强度，而这项测量差不多是后追加上的项目。
During the nights, not only were the concentrations of ozone, nitrogen oxides and other gases measured by this plane, but also, almost as an afterthought, the intensity of the light from below.
如果机舱里有烟雾，把身体放低到烟雾与有毒气体的下面爬行，这样你能在你离开飞机前保持呼吸。
If there's smoke in the cabin, get low and crawl below the level of the smoke and toxic fumes, so you can breathe until you get out of the plane.

All aircraft generate two cones, at the nose and at the tail.
除了二氧化碳，飞机还释放出另外一种有害气体——一氧化碳。
As well as carbon dioxide, planes emit nitrogen oxide, another nasty gas.
后来证实，航天飞机的外层热防护在发射时就被损坏，使得超热气体渗入机舱内，导致机毁人亡。
It later emerged that the spacecraft’s heat shield had been damaged on launch, letting superheated air inside and tearing it apart.
我们有信心制造出使用更少燃料、排放更少气体、运行更为安静的航天飞机，而我们也正致力于实现这个伟大的目标。
We believe it is possible to build an aircraft that uses less fuel, gives off fewer emissions, and is quieter, and we are working on the technologies to create that aircraft.
使事情更糟的是全世界的飞机把几十亿吨的二氧化碳等温室气体直接排入地球大气中，这极大地危害到我们的环境。
To make things worse, planes across the world emit billions of tons of greenhouse gases such as carbon dioxide directly into earth's atmosphere, which poses the worst danger to our environment.
畜牧业产生的温室效应气体，大过全球的小客车、卡车、火车、船、飞机的排放量总合。
Greenhouse gases produced by the farm animal industry greatly surpass the total amount of the world's transportation emissions.
相较上世纪六十年代声音巨大的喷气式飞机一台现代的涡扇发动机噪音水平降低了80%油耗也下降了一半同时温室气体排放量也有所下降。
Compared with a rowdy 1960s jet, a modern turbofan is some 80% quieter and burns as little as half as much fuel—thus producing fewer greenhouse gases.
与航空飞行器相比，高速铁路由于还要面临地面气流的扰动，两车交会时气体的震荡，以及车体通过隧道时的气流变化，因此高速列车的头型设计比飞机更具挑战性。
Compared with the spacecraft instrumentation, the ground air disturbance, the unsteady aerodynamic flow on crossing event and inside tunnel impose more challenges on the head design of HSR trains.
富人的生活趋向于放出更多的温室气体，因为他们会更多驾驶燃油汽车，更频繁的坐飞机旅行，生活在大房子了，从而需要更多的燃料来取暖或者制冷。
Rich people's lives tend to give off more greenhouse gases because they drive more fossil-fueled vehicles, travel frequently by air and live in big houses that take more fuel to heat and cool.
另外，在飞机降落过程中，富氮气体还可用于。
In addition, the nitrogen rich gas is used for fuel tank pressurization during descent.
飞船、宇航探测器、航天飞机等复杂外形航天器给气体动力学，包括稀薄气体动力学提出了新的要求。
The flight of space vehicles, probes and shuttles set new demand on gas dynamics, including rarefied gas dynamics.
2010年1月27日-气体和尘埃螺纹围绕一个恒星的物质飞机从胚胎倒在一个艺术家的庞大的原恒星w 33 A呈现两极。
January 27, 2010 - Gas and dust whorl around a stellar embryo as jets of material pour from the poles in an artist's rendering of the massive protostar W33A.
在10公里高空处，这是多数航班的飞机高度，但是飞机在这一高度的臭氧层很容易形成氧化氮气体，氧化氮气体可使地球温度升高。
At around 10 kilometres up, where most airliners fly, NOx is very efficient at creating ozone, which at these heights helps to warm the planet.
