吉本斯解释:“这就像一个不需要淀粉或者纤维素就能生产出生物燃料分子的小型工厂。”
"They are like little factories that spit out biofuel molecules without the need for starch or cellulose, " explains Gibbons.
几个世纪以来,牛津大学一直是英国知识分子的中心,它或许是欧洲众多古老大学中最负盛名的。
For centuries Oxford has been at Britain's intellectual heart, perhaps the most prestigious among Europe's many ancient universities.
一些美国人把牛津视为知识分子的乐园。
So let's figure out the bond order for our two molecules here that we figured out the electron configuration for.
让我们看看这里,两个分子的键序是多少。
And you would find that the bond energy of the heteronuclear molecule was nowhere on the average of the two.
你将发现,电子相同的分子的总能量,并不是平分的。
So what we can actually directly compare is the dissociation energy or the bond strength of nitrogen versus hydrogen.
因此实际上我们可以直接进行比较,对氮分子与氢分子的离解能,或键的强度。
