We've talked about one the main concepts in physiology being homeostasis, that is 'how do you maintain a constant internal environment?

我们讲到了生理学的主要概念,内稳态,即如何维持内环境的稳定

So, these are all involved with our ability to maintain homeostasis by exchanging materials with the external environment.

这个过程关乎人体维持内稳态的能力,内稳态通过与外环境进行物质交换来实现

And then we said you can also achieve octet stability and electron transfer if you look at elements that are just a little bit rich of electrons versus octet stability or a little bit lean of electrons.

然后我们说你还能达到8电子稳态,以及电子的转移,如果你看看,那些电子较多的元素,违背8偶律，或者有一点缺电子。

Those foods that you see there, that throw off the animals homeostasis, and their hunger equilibrium are the same foods that are marketed very heavily.

你们看到的这些食物,打破了这些动物的内稳态和饥饿平衡,这些食品占据了大量市场份额

So, if we want to go from that stable state to that less stable state, we need to put in a certain amount of energy to our system, that difference between the free electron and the electron bound to the metal.

所以，如果我们想使电子,从稳态到达不够稳定的状态，我们需要引入一定数量的,能量到系统中，即自由电子和束缚于金属的,电子的能量差。

Your body has elaborate mechanisms for maintaining this state of homeostasis, that is, things staying the same; the body stays the same, homeostasis.

你的身体有许多精妙的机制,来维持内稳态,也就是说体内物质不改变,身体状态不改变,这就是内稳态

耶鲁公开课 - 生物医学工程探索课程节选

So homeostasis is enabled by sometimes complex, sometimes very simple control mechanisms.

通过一些或复杂或简单的机制,使内稳态得以实现

And this occurs in order to achieve octet stability.

这些的发生是为了达到8电子稳态结构。

Well that process of control to maintain a constant environment inside our body, whether it's an environment of constant mass or constant composition, or constant temperature, is called homeostasis.

这个控制过程维持着,体内环境的恒定,不论是内环境中物质的量的稳定,或者成分的稳定,或温度的稳定,这种状态叫做内稳态

The main function of all your cells, and all your tissues, and all your organs is to maintain this homeostasis, which allows you to live in a changing environment.

你所有细胞,所有的组织,所有的器官最主要的功能,就是维护这个内稳态,使你能够以不变应万变

耶鲁公开课 - 生物医学工程探索课程节选

Stability is at the bottom.

稳态在最底层。

How do those differences between cells contribute to the properties of the tissues, which contribute to the properties of the organs, which contribute to the properties of a person and this maintenance of homeostasis?

这些差异化的细胞,是如何构成具有不同属性的组织,这些组织又构成具有不同属性的器官,器官又构成了不同的人,它们是如何维护内稳态呢

So here we have energy increasing on the y-axis, and you see this straight line at the bottom here is lower down on the graph, and that's the energy of a bound electron, so that's going to be a low stable energy.

这里我们看到能量沿着y轴增加，而且在这张图片上,这条直线在底部是降低的，那是一个束缚电子的能量，所以那是一个低稳态能量。
