atmospheric definition───大气定义
Plants are the main source of atmospheric oxygen.───中的氧主要是由植物产生的。
Usually, atmospheric oxygen content is about 20%, carbon dioxide containing about 0.03%.───通常,大气中的氧气含量约为20%,二氧化碳约含0.03%。
As atmospheric oxygen levels fall, less oxygen will dissolve in seawater, depleting levels slightly.───由于大气中氧气含量的减少,较少的氧气溶于海水,使得海水中的含氧量轻微的减少。
When plants conquered the land they found new places to grow and new ways to be buried, gradually boosting atmospheric oxygen.───当植物破土而出,他们发现了新的空间去生长以及新的方式去深埋,这样的过程逐渐增加了大气中的氧气。
Rust is the product of a slow combination of iron with atmospheric oxygen and water vapor.───锈是铁和空气中的氧和水蒸汽缓慢结合的产物。
Atmospheric oxygen levels probably decreased, suffocating any organisms that couldn't cope.───大气中的含氧量也许会下降使任何生物都无法承受窒息而死。
Plants are the main source of atmospheric oxygen.───大气中的氧主要是由植物产生的。
Plus you will be helping to save our dwindling supply of atmospheric oxygen.───另外,您将帮助拯救我们的供应越来越少,大气氧。
At that point, rocks from the era show that atmospheric oxygen started to rise, which would suggest that methane levels dropped.───来自那个时代的岩石表明大气中氧的含量开始上升,可能意味着甲烷含量有所下降。
