在一般情况下，大气中的含氧量为21%左右。据科学家研究，大气的含氧量如果超过35%，那是很危险的，大气极容易产生自燃，地球随时随地都有可能发生火灾，那时，地球就会成为一片火的海洋，成为生命的一座地狱。

In the power plant, the excess oxygen in flue gas has been measured and used to control the combustion efficiency. For coal-fired power generation, this approach may have some shortcomings result from air ingress and other factors.
在火电厂中一直是测量燃烧过程出口的烟气含氧量来控制燃烧效率。

雨水浸透的土壤比干燥的土壤含氧量少。
然而我们现在知道了，由于中生代空气的含氧量比我们想象的要低得多，所以蜥脚类动物可食用的植物也比我们想象的要少得多。
However, we now know that since oxygen levels were much lower in the Mesozoic than we assumed, there was much less plant life for sauropods to eat than we thought.
