Between 1990 and 2008, for example, European Union countries reduced total carbon emissions in their own territories by 6%.

比如，在1990年和2008年间，欧盟国家在其领土内减少了碳排放总量的6%。

The model also showed that dust deposited in oceans increased carbon uptake from the atmosphere by 6 percent, or 4 ppm, over the same time period.

该模型也显示在同一时期，灰尘存在于海洋从大气中碳摄入量增加了6到4个百分点。

We have carbon 12. I will even leave off the 6 because we already know it is carbon.

我们有碳12，我们将6省去6，因为我们已经知道它是碳了。

India's stance, going into the Copenhagen summit, which begins December 6, is that poorer nations should be exempt from legally binding caps on carbon emissions.

VOA: standard.2009.11.08

So why don't you go ahead and identify the correct electron configuration for carbon, 6 and I'll tell you that z is equal to 6 here.

所以你们为什么不开始,而且识别碳的正确的在你们做作业方面,电子构型，我会告诉你有效电荷量是。

So, shared electrons are the ones that are shared between the carbon and the nitrogen, so we have 6 shared electrons, and we want to take 1/2 of that.

共用电子是那些在碳和氮之间,被它们共用的电子，那么我们有六个共用电子，然后我们要给它乘上二分之一。
