When plant leaves get damaged, whether by hungry insects or an invading lawn mower, they release plumes of volatile chemicals.

当植物叶子受到损伤，如被饥饿的虫子吃或者被除草机割时，它们会释放一缕缕挥发性的化学体。

They also measure volatile organic compounds, such as formaldehyde, contained in building materials or household products.

他们还测量建筑材料或家用产品中所含的挥发性有机化合物，例如甲醛。

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。

The walking catfish will shimmy towards attractive volatile amino acids while steering clear of foul waters emanating hydrogen sulfide.

行走的鲶鱼会向有吸引力的挥发性氨基酸摆动，同时避开散发硫化氢的污浊水域。

The first one is where manufacturing takes place, There is another one for storage of dangerous and possibly volatile products.

第一个是制造地，另一个是储存危险和可能挥发性产品的地方。

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。

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。

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。

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。

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，预点火是燃料在最佳时机之前燃烧的趋势。

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料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。

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，美国关于车辆排放和体含量的法规降低了空中的挥发性化合物和烟雾浓度。

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.

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

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进入设备, 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。

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，另一个则毫无味，以此作为实验对照。

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，如果你在烹饪香料，你想释放出那些奇妙的、芳香的、挥发性的味，这很重要，但如果你慢慢地低温烹调，你就可以掌控。

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皿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进行相互作用。

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，当我把分子吸进鼻子时，这个过程就开始了。这意味着你要能闻到什么，味必须是挥发性的，或者处于态，被吸进鼻孔。
