一位生态学家曾经问一个男孩，他认为保护环境意味着什么。

An ecologist once asked a boy what he thought it meant to protect the environment.

但是如今一位生态学家提出，气候变化的效应将比人们认识到的更复杂——而且甚至可能减少一些传染病的发病率。

But now an ecologist argues that the effects of climate change will be more complex than has been acknowledged - and that there may even be a reduction in the incidence of some infectious diseases.

这些能量态的水平代表0或者1，就像传统计算机使用晶体管的开关状态来代表数据位0或1一样。

Those levels represent a one or zero, just as the off and on states of a transistor correspond to zero or one bits of data in traditional computing.

So the point is, this balance between energy thatyou could think of as say bond energies in chemical reactions, and entropy that you can think of in terms of disorder, how many different possible combinations or configurations of something wrong, will dictate where the equilibrium lies.

关键在于，这种能量与熵之间的平衡,确定了平衡的条件，在化学中能量涉及键能，而熵和无序有关,即有多少可能的不同组合或者形位，二者的平衡会告诉我们平衡态是什么样子。
