So in one case, we could actually put carbon in the middle, in one place, we could put sulfur in the middle, and in one case we could put nitrogen.
那么有一种情况是,我们把碳放在中间,还有一种情况是,把硫放在中间,另外一种情况是把氮放在中间。
Many harmful or controversial forms of pollution are either not measured - as is the case for carbon dioxide and small particle emissions - or the data is not made public, as is the case for ozone.
许多有害的或者有争议的污染物也未计算在内——比如说二氧化碳和小颗粒排放,或者其污染数据未公之于众——比如说臭氧层的破坏程度。
If I've not misunderstood, the author's case is a voluntary carbon market case, but it fundamentally involves REDD.
如果我没有理解错的,作者的案例是一个志愿碳市场的案例,而从根本上涉及到REDD。
So let's take the case of acetylene where we have two carbon atoms that are going to be triple bonded to each other, each are bonded to a carbon and then to one hydrogen.
让我们来看一看乙炔的例子,我们有两个碳原子,成三键,每个碳和一个碳一个氢相连。
As we see a little bit later, I could talk about the carbon-hydrogen bond in methane where there is a plurality of bonds. In this case, there is only the one bond but I just want to get the formulas.
因为我们后来看到一点点,我能讨论甲烷中的碳氢共价键,那有许多共价键,这种情况下,这只有一条共价键,但我想得到氟。
So in one case, we could actually put carbon in the middle, in one place, we could put sulfur in the middle, and in one case we could put nitrogen.
那么有一种情况是,我们把碳放在中间,还有一种情况是,把硫放在中间,另外一种情况是把氮放在中间。
