According to carburizing steel's chemical composition and ore's case carbon requirements, the carbon potential of furnace inside atmosphere is controlled quantitatively.
根据所采用渗碳钢的化学成分及渗件表面合联量,对炉气联势进行定量控制。
Yes, when most people think about cars and fuel, they think about all the carbon dioxide that's produced, but they don't realise that that wasn't always the case.
是的,当大多数人想到汽车和燃料时,他们想到的都是其产生的二氧化碳,但他们没有意识到情况并非总是如此。
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。
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。
