"If they don't get injections or oxygen from the Ministry of Finance, then this patient would die."

That is metallic sodium that would keep in kerosene so it doesn't react with the oxygen in the air.

金属钠应该保存在没有中,这样它就不会和空气中的氧气反应了。

It's easy to write the skeletal structure, because it's all oxygen, we don't have to worry about what's going to go in the middle.

画它的骨架结构很容易，因为它们都是氧原子，我们不需要担心哪个原子在中间的问题。

But, in an internal combustion engine what happens is we don't have an oxygen tank.

但是在一个内燃机中,如果我们没有氧气罐会发生什么呢。

This is exactly where I don't really know the details, but I take it it's something like: because of whatever the original input was, eventually the blood's no longer circulating and oxygen isn't making its way around the body.

事实上我对这方面不是很了解,我只能认为是,不论最初的死亡原因是什么,最后血液不再流动,氧气不能输送到全身

It occurs because blood flow gets reduced in that blood vessel and so the heart muscle, which is actively beating all the time, needs large quantities of oxygen provided by blood can't get the blood through the vessel.

发病原因是冠状动脉血流量降低,因为心肌搏动永不停歇,随时需要血液供给大量氧气,发病时血液无法正常流过血管

So, let's just arbitrarily put it between these two in this case here, but actually there's no reason we couldn't also put it between oxygen b and c, so I'm going to draw another structure where we have it here.

那么，让我们任意地将它们放在这两个之间，但实际上我们没有理由,不能把它们放在氧原子，B，与，C，之间，因此我将把另外一个结构画在这里。
