二氧化碳的密度分布和自由能分布有一个明显的“镜面对称”的结构，高密度区域对应自由能的深阱。

The density profile and the free energy profile of carbon dioxide have a "mirror symmetry", where the high density coincides with the free energy well.

大气中较高密度的二氧化碳会使某些地区的植物更有效的利用水(它们进行光合作用时的水分流失会更少)。

Higher concentrations of carbon dioxide in the atmosphere may make plants use water more efficiently in some parts of the world (they will lose less moisture during photosynthesis).
