Based on the Boltzmann equation for the equilibrium state, the 1D and 2D shallow water equations were derived from the basic relationship between macroscopic and microcosmic variables.
应用宏观和微观变量基本关系式,以平衡态的Boltzmann方程为基础,导出了基于Boltzmann方程的一维和二维浅水流动方程。

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。
OK, so now let's try to formulate how to describe the equilibrium state and what dictates spontaneity.
现在我们尝试,找出如何描述平衡态以及,什么东西表明自发性。
The equilibrium state is the one, and it's just one, in which there are no spontaneous changes that can take place to any other state.
平衡态是一个,而且仅仅是一个态,这个态不会发生自发变化,变成其他的态。
