So what they do is, they're describing how these thermodynamic properties change, in terms of only state functions and state variables.

他们的作用是描述,随着状态函数和状态变量的变化，系统的热力性质如何变化。

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。

You simply want to describe things the way they are and then dynamics tells you how they changed and why they changed.

你只是单纯描述物体的实际状态,而动力学则是解释它们运动的方式和原因的

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。

For real gases, there's a whole bunch of equation the states that you can find in textbooks, and I'm just going to go through a few of them.

这是理想气体的状态方程,对实际气体,你可以在教科书里，找到许多描述它们的,状态方程。

So the system will not be described by a single state variable during the path.

因此系统将不能被,路径上的单一状态变量描述。

for real gases. This is an equation of state for an ideal gases.

我们需要描述实际气体,的状态方程。
