Nitrogen gas (N2) makes up 78 percent of our atmosphere, but most organisms cannot utilize this source of nitrogen to grow, because the nitrogen atoms are held together by a tight triple bond so strong that it requires extreme temperatures and pressures to break.

氮气构成了大气的78%，但是大部分的有机物不同利用这一资源来生长，因为氮原子十分坚固的固定在了一起，他们需要特别的高温高压才会被分裂进而被生物利用。

An unsaturated fatty acid whose carbon chain has one double or triple valence bond per molecule; found chiefly in olive oil and chicken and almonds.

碳链的分子均有一个二价三价键的不饱和脂肪酸，主要存在于橄榄油、小鸡和杏仁中。

"It turned out that our first bet, a double or triple carbon-carbon bond, placed next to the transferable carbon unit, helped to alleviate the problems that had plagued the reaction in previous studies," Klimasauskas said.

&结果证明我们先前的推测是正确的，双键或三键被放置在要转移的基团旁边时，会帮助减轻先前研究中提到的问题，&Klimasauskas说。

Unbranched hydrocarbons having one triple bond are named by replacing the ending -ane of the alkane name with -yne.
