organic carbon

基本解释

Soil is collected with a probe to determine the amount of organic carbon sequestered in it.
用一个取样器把土壤收集起来，以确定固存在里面的有机碳的含量。
Such an environment would have to contain the basic ingredients of life—including water, organic carbon and a source of energy to sustain the microbes' metabolism.
这样的火星环境也许包含了一些基本的生命要素——包括水，有机碳和维持微生物新陈代谢的能量源。
Scientists believe deltas next to the lake may well hold secrets about past life on Mars as such places on Earth have become the natural deposits of organic carbon and other markers of life.
科学家认为，湖泊附近的三角洲可能完好地保存有生命存在的秘密，因为地球上类似的三角洲也是有机碳和其它生命标志物的天然寄存地。

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。

So if you're trying to make a more complicated organic molecule carbon-carbon bonds are one of the most difficult things to make in organic chemistry, and it turns out that c n minus is a very reactive molecule, so it's a good way, even though we'll go over some drawbacks in a second, it is a good way to make carbon-carbon bonds.
如果你要合成一个更复杂的有机分子,碳碳键是有机化学中,最难制造的键之一，而实际上氰离子是一种具有很高活性的分子，用它是一个好办法，尽管我们一会儿将看到它的一些缺点，但它的确是一个制造碳碳键的好方法。
