So, these on-changing properties that describe the state of the equilibrium state of the system are called state variables.
这些描述,系统平衡态的,变化的属性,就叫做状态变量。
And in the end, when it's at equilibrium, and you look and you'd make a measurement, right, you could do spectroscopy.
当他处于平衡状态的时候,你可以做测量,比方说做光谱分析。
hey reach a certain equilibrium.
从而达到一种平衡状态。
The balance of sodium movement relative to potassium movement changes because there's this resting movement of all these molecules anyway, but that balance changes dramatically when these ion - when these gated ion channels open.
钠钾各自运动始终保持动态的平衡,因为尽管在静息状态,所有这些离子也在运动,但是平衡的剧烈变化,只发生在这些门控离子通道打开的时侯
So the state variables describe the equilibrium's state and they don't care about how this state got to where it is.
状态变量,描述平衡态,它们并不关心,系统是如何演化成这样的。
In the biochemical reactions that are taking place in your body, there is equilibrium between a whole myriad of reactants and products, and thank heavens that gets maintained.
在我们身体内进行的,生物化学反应中,大量的反应物和产物,也是处于平衡状态,谢天谢地实际情况就是这样。
The one that is at equilibrium, there is only one macroscopic state at equilibrium.
处于平衡的状态,并且只有一个平衡的宏观状态。
It's at equilibrium, under the new condition, that is with the barrier removed.
系统在新的状态下处于平衡,这个新的状态就是指隔板被取走了。
And u is minimized at equilibrium.
这说明平衡状态下内能u是最小的。
In some sense, that's one reason to associate this as a kind of energy, H just like mechanical energy u or enthalpy H, it's the minimum free energy state that is the equilibrium state under the relevant conditions.
在某种意义下,这是我们把这些物理量称为能量的原因,就像机械能U和自由焓,具有最小自由能的状态在特定的条件下,就是平衡态。
