The hyperconjugation between lone-pair of nitrogen atoms and nitrogen-nitrogen bonds, or among nitrogen-nitrogen bonds play a significant role on the nitrogen-nitrogen bond length.

氮原子孤对电子与氮氮键以及氮氮键相互之间的超共轭作用是影响氮氮键长的重要因素。

The nitrogen atoms of amines have what chemists call a lone pair of electrons, and it is this which attaches each amine molecule to the nanotube.

胺上的氮原子存在着一种电子对，化学家们管这叫孤对电子（译者：嘿嘿~高中知识竟然还未忘记），而正是这些孤对电子把胺分子牢牢绑在纳米管上。

The pair considered three aspects of global livestock production: greenhouse gas emissions, biomass consumption and nitrogen emissions.

两位研究人员考虑了全球畜牧业生产的三个方面：温室气体排放，生物质消耗和氮排放。

So in terms of nitrogen that starts off with a valence number of 5, again we have 2 lone pair electrons in the nitrogen, and again, we have 6 electrons that are shared.

对于氮来说,我们应该从五个价电子开始，同样，氮也有两个孤对电子，共用电子的个数也一样，是六个。
