So homeostasis is enabled by sometimes complex,

通过一些或复杂或简单的机制
sometimes very simple control mechanisms.

使内稳态得以实现
These are mechanisms that can be described

这些过程说起来
not too differently from mechanisms

与你们熟悉的环境稳定机制
that you're familiar with for maintaining homeostasis.

并无太大不同
For example, the thermostat in your dorm room.

比如你卧室里的恒温器
Maybe you don't control thermostats in your dorm room,

可能你根本就不理卧室里的恒温器
some of you do and some of you don't probably,

有些人去调它有些人就置之不理
and maybe it doesn't work very well

可能它压根就是坏的
so it might not be a good example,

所以这个例子也许并不恰当
but imagine a perfect thermostat that you set for a temperature

但你还是想象一个完美运行的恒温器
and then the temperature stays the same inside the room

你设定温度后房间里的温度就保持不变
