它的分解反应速率对有效氧含量是零级的，对水汽分压是一级的。

The dissociation rate is zero order with respect to its effective oxygen content, and is first order with respect to the water vapor pressure.

当海洋变暖时，海水表面会形成更稳定的薄层，薄层会影响水面上营养物质的有效性，更让人焦虑的是，会影响到氧的使用。

Surface waters are expected to form more stable layers as the oceans warm, which will affect the availability of nutrients and, it is increasingly feared, of oxygen.

So let's do this considering, for example, what it would look like if we were to write out the electron configuration for oxygen where z is going to be equal to 8.

我们来做这个考虑，举例来说,如果我们写出,有效电荷量为8的氧的电子构型。
