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。

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。

We often assume in finance that random variables, such as returns,are normally distributed.

金融学中我们常假设随机变量,例如收益率,是服从正态分布的

We're going to find other properties that do care about the history of the system like work, that you put in the system, or heat that you put in the system, or some other variables But you can't use those to define the equilibrium state.

我们还会发现其他一些,与系统的历史有关的性质,比如你对系统做的功，或者你向系统传递的热量，或其他的变量,但你不能用它们,来定义平衡态。
