This is because warm air doesn't rise in space, so sleeping astronauts in poorly ventilated sections can wake up gasping for air, surrounded by an invisible bubble of their own exhaled carbon dioxide.

这因为暖空气在太空中不会上升，所以在风不畅的地方睡觉的话，醒来时你会发现，被自己出的二氧化碳组成的无形气泡包围了，会喘不气来。

Wearing bright colors is also not a wise choice, since she hunts by both sight and smell, the latter depending chiefly on the amount of carbon dioxide exhaled by the potential target.

穿亮色衣服也不个好选择，因为她挑选猎物靠的视觉和嗅觉，后者尤其着重潜在目标出的二氧化碳含量。

These are microscopic particles that people exhale just by breathing and speaking.

这些人们仅吸和讲话即可出的微小颗粒。

So London in particular, as you get to the center, it becomes a complete gridlock where you breathe diesel fuel all the time, and when you get home, you will blow black dust out of your nose.

所以特别伦敦，你到达市中心的时候，那里的道路就完全阻塞了，你在那儿吸的柴油燃料，等你到家的时候，从鼻子里都能出黑色的灰尘来。

It should feel like more air is coming in than out.

出的空气需要少于吸入的空气。

See your, let me fix that up, see your or see my breath.

看到你的，让我修改下，看到你或我出的气。

On Earth, the forests and oceans absorb the carbon dioxide we exhale.

在地球上，森林和海洋吸收我们出的二氧化碳。

And they spiked these exhalates with 1,000 parts per billion H2S.

他们在袋子里出的气中加入了十亿分之千浓度的硫化氢。

They have found a way to breathe the booze out.

他们找到了种把酒给出来的方法。

With his warm breath he gently fanned, the tresses fair and long.

伴着出的温暖气息，它用长毛给孩子取暖。

This gets rid of the waste carbon dioxide exhaled by the astronauts.

There was a mixture of scotch and champagne on his breath.

Whew, chilly. I think I can see my breath.

气氛降至冰点，冷得都能看见我出来的气了。

Let the air out of your mouth.

It travels through the bloodstream to tiny air sacs in the lungs, passing into exhaled air at a concentration 2,000 times lower, on average, than in the blood.

它血流到达肺中的微小气囊，进入出的空气中，其浓度平均比血液中的浓度低2，000倍。

When that air mixes with the air deep in your lungs — including a lot of air that you haven't exhaled yet — the partial pressure of oxygen drops to about 104 millimeters of mercury.

这些空气和你肺部深处的空气混合时——包括许多你还没有出的空气——氧气的分压下降到大约 104 毫米汞柱。

For that reason, the maximum amount of air people with COPD can breath out in a single breath, known as the FVC, or forced vital capacity, is lower.

因此，慢阻肺患者口气可以出最大的气体量，称为FVC，即用力肺活量，会较低。

The carbon dioxide and other gases you breathe out also contain plenty of moisture from your mouth and lungs in the form of water vapor.

你出的二氧化碳和其他的气体还包括很多来自于你的嘴巴和肺的水汽，以水蒸气的形式。

They are, therefore, appropriate for situations when the threat comes from objects smaller than exhaled droplets- meaning less than about five microns across.

因此，它们适用于威胁来自比出的飞沫还小的物体时，也就径小于5微米的物体时的情况。

Fabric was used rather than exposing the volunteers themselves, to exclude the effects of exhaled carbon dioxide, which is another important cue for mosquitoes.

为了排除出的二氧化碳的影响，研究使用织物而不接暴露志愿者皮肤，二氧化碳另个主要影响因素。
