It is produced by reaction of water with calcium carbide, passage of a hydrocarbon through an electric arc, or partial combustion of methane. Decomposing it liberates heat; depending on degree of purity, it is also an explosive. An acetylene torch reaches about 6,000 °F (3,300 °C), hotter than combustion of any other known gas mixture.

乙炔的制法有三种︰水与碳化钙反应、烃经电弧的作用和甲烷的不完全燃烧。分解乙炔会释放出热量,纯度如果高就容易爆炸。乙炔氧焰最高可达到火焰温度6,000℉(3,300℃),比所有已知可燃混合气体都高。

||1: Whether peat-bog fires are being encouraged by climate change is debatable. But it is clear that they release prodigious quantities of climate-changing carbon dioxide when they happen. ||2: And even in the absence of fire, draining peatlands—for example, for agriculture—liberates a lot of carbon dioxide. ||3: In Russia such drainage is reckoned to free 160m tonnes of the gas every year. In Indonesia the figure is 508m tonnes. ||4: All told, the global total is about 1.3 billion tonnes—6% of man-made carbon-dioxide emissions even without the effect of fire. That is far more than the contribution made by aviation, for example.

||1:虽然泥炭湿地大火是否是由气候变化所引发的仍有争议，但当火灾发生时，它们会释放出大量致使气候变化的二氧化碳却显而易见。||2:即使在没有火灾发生的情况下，排水后的泥炭地（比如让地于农业）就会释放出大量二氧化碳。||3:在俄罗斯，这类排水后的泥炭地估计每年释放出1600万吨的气体，而在印度尼西亚，该数字是5080万吨。||4:全球排放总量约为13亿吨，即使在没有火灾发生的情况下依然占人类二氧化碳排放总量的6%，远高于航空业所作的"贡献"。

Apple's aversion to big mergers or acquisitions also liberates senior managers from this most tedious, and often disastrous, path to growth.

苹果排斥大型并购，这也解放了其高级管理人员，让他们不必走上这条最为乏味、并且通常会造成灾难的增长道路。
