Each insect was placed for five minutes in an apparatus that had two chambers, one of which contained a sample of the volatiles and the other an odourless control.

每只昆虫都被放置在一个两室装置内五分钟，一个腔室内含有挥发性物质的样本，另一个则毫无气味，以此作为实验对照。

In addition to the volatile organic compounds like ethanol we consume in food and drink, the biochemical processes of our cells produce many others.

除了我们在食物和饮中消耗的挥发性有机化合物（例如乙醇）之外，细胞的生化过程还会产生许多其他元素。

Now, the process starts as I sniff molecules up into my nose. This means that for you to be able to smell something, the odorant must be volatile, or in a gaseous state to get sucked up into your nostrils.

现在，当我把分吸时，这个过程就开始了。这意味着要能闻到什么，气味必须是挥发性的，或者处于气态，被吸孔。

Wolfe and his colleagues identified the microbial interactions by growing various cheese-dwelling fungi and bacteria in separate but adjacent dishes in the lab. The microbes couldn't touch-they could interact only via the volatile compounds they released.

沃尔夫和他的同事们（通过在实验室分离相邻培养中各种寄生于奶酪的真菌和细菌）来确定微生物之间的相互作用。微生物之间不能相互接触，它们只能通过释放的挥发性化合物行相互作用。

Bear in mind, if you are cooking spices, you want to release those fantastic, aromatic, volatile flavours, that's important, but if you do it low and slow, you keep control.

记住，如果在烹饪香，释放出那些奇妙的、芳香的、挥发性的味道，这很重要，但如果慢慢地低温烹调，就可以掌控。

So, what we do is allow the subject to blow into the device, we extract out the volatile organic compound we wish to measure, in this case acetone.

因此我们做的就是允许检测目标入设备, 然后我们回提取希望测量的挥发性有机化合物, 在这种测试下是丙酮。

Given a dog's acute sense of smell, scientists think canines can pick up on volatile organic compounds that cancer cells give off.

鉴于狗狗敏锐的嗅觉，科学家们认为，犬科动物可以闻到癌细胞释放的挥发性有机物。

This notion was reinforced by the discovery that the rocks were lacking significantly in what scientists call " volatile elements" .

这个从发现得到的补充概念是石头缺少值得注意的被科学家称之为“挥发性成分”的东西。

That, she explains, is because vanilla is one of the volatile flavour compounds present in breastmilk, as well as some formulas.

她解释说，这是因为香草是在母乳和一些配方奶粉中存在的挥发性风味化合物之一。

Messenger's evidence of the volatiles on Mercury's surface and the unusual size of its core suggests an interesting new theory.

“信使号”关于水星表面的挥发性物质及其核心异常大小的证据表明了一个有趣的新理论。

Both gasoline and diesel are volatile fuels, though gasoline is the more volatile of the two.

汽油和柴油都是挥发性燃，尽管汽油的挥发性更强。

But it's not like you can't taste anything — it's just that more subtle flavors involve more volatile compounds that are picked up by your olfactory receptors.

但不是说什么都尝不到——只是更微妙的味道包含了更多的挥发性化合物，这些化合物会被的嗅觉受体吸收。

However, higher volatility increases knocking or pre-ignition; for beginners, pre-ignition is the tendency of the fuel to combust before the optimum timing.

但是，较高的挥发性会增加爆震或预点火；在刚开始时，预点火是燃在最佳时机之前燃烧的趋势。

And when something disrupts those processes, like a disease, the collection of volatile organic compounds in the breath may change, too.

当某种东西（如疾病）破坏这些过程时，呼吸中的挥发性有机化合物也会发生变化。

So we're looking at volatile organic chemicals that may get into building air into classroom spaces because of things that are in those classrooms, like 3D printers, for example, additive manufacturing.

因此，我们关注的是可能入建筑物空气、而渗透至教室空间的挥发性有机化学物质， 这些污染源来自教室内的设备，比如3D打印机， 即增材制造设备。

It's still arguable whether it will be a gass-like Radon, or it may be a solid, just like some of the other elements, perhaps a solid that's rather volatile.

它仍然有争议是否像氡一样是气态的，或者可能像其他一些元素一样是固态的，也许是一种相当挥发性的固态。

And as soon as you swallow, The air is going to take the volatile up into your nose and you're going to perceive the flavor.

当一吞下去，空气就会把挥发性的物质带入的， 就会感受到这个味道。

Next up, scientists say your couch could be emitting toxic vapors, specifically volatile organic compounds that could pose potential health risks, especially in indoor environments.

接下来， 科学家指出， 您的沙发可能会释放有毒蒸汽，特别是那些可能带来潜在健康风险的挥发性有机化合物，尤其在室内环境中。

Similarly, regulations on vehicle emissions and gas content in the US reduced the volatile compounds in the air and smog levels along with them.

同样，美国对车辆排放和汽油成分的监管减少了空气中的挥发性化合物及其伴随的烟雾水平。

Meteorites are especially useful for measuring the  abundances of volatile elements like hydrogen, helium, and noble gases that are  underrepresented in stellar photospheres.

陨石在测量氢、氦及稀有气体等挥发性元素的丰度方面尤为有用，这些元素在恒星光球层中含量较低。
