If you go to visit Nobel? S old residence, the house in which the great chemist remained a bachelor throughout his life, you will catch sight of a shelf laden with experimental records.
如果你参观诺贝尔的故居-在那座房子里,这位伟大的化学家过了一辈子的独身生活-你将会看到一个堆满实验记录的书架。
Developed c. 1972 largely by British chemist James E. Lovelock and U. s. biologist Lynn Margulis, the Gaia hypothesis is named for the Greek Earth goddess.
约在1972年由英国化学家洛夫·洛克与美国生物学家马古利斯阐述,盖亚假说以希腊大地女神命名。
Chemist: Sorry, Sir. I can not sell it, you must first get a doctor "s certificate or prescription."
药剂师:抱歉,先生。我不能买给你。你必须有医生的证明或者医生开的药方才行。
N 2 So any chemist should be able to just look at n 2 and know that it's a triple bond, but that's not something that we've learned how did to do yet, so let's go ahead and start a new topic that's going to allow us to have some sort of sense of what the valence electron configuration, which includes whether something's a single or double or a triple bond can be figured out for any given molecule.
任何一个化学家都应该能够仅仅通过看到2,就知道它有一个三键,但是我们还没学习如何做到这点,因此下面我们就开始进入一个新的主题,它将使我们能够有一定的认识,对于价电子的排布情况,包括可以对任何一个给定分子中的键是单键双键,还是三键作出判断。
I'm an organic chemist, so I love carbon, it's one of my favorite atoms to talk about, but it would be nice to get to the point of bonding and even reactions to talk about all the exciting things we can think about once we're at that point.
我是个有机化学家,我喜欢碳原子,这是我最喜欢谈论的原子之一,但我更喜欢讲成键,甚至化学反应的概念,一旦到了这之后,我们就可以考虑各种激动人心的事情。
This is a convention that organic chemist's use when they're describing molecules like this.
这种称谓是一种惯例,是有机化学中描述像这样的,大分子时使用的
