Researchers have long known that greenhouse gases might help the layer recover by cooling the stratosphere, which slows the rates of chemical reactions that destroy ozone.

长期以来，研究人员已经了解到：温室气体通过对同温层的冷却作用，可以放慢破坏臭氧层的化学反应速度，因此也许会有助于臭氧层的恢复。

The one they favoured is that the higher temperature of the tropics means that chemical reactions happen faster and metabolic rates are therefore higher.

而他们所推崇的一种假说认为热带地区的温度更高意味着化学反应发生的速度更快，因此生物代谢的速率也更快。

The rates are far more important than the thermochemistry of the chemical reactions taking place.

这速度远比发生热化学反应的热化学重要。

In addition, the theory of homeopathy actually defies conventional scientific understanding--in particular, the law of mass action, which demands that the rates of chemical reactions be proportional to the concentrations of substances involved.
