此外，根据抽象性和不稳定性来测量系统平衡将使您不断的了解系统的可维护性。

In addition, measuring your system's balance in terms of abstractness and instability gives you an overview of its maintainability over time.

So that's a big help. And equilibrium happens when there isn't any possible change of state that would satisfy this.

这个非常方便，当所有的变化,都无法满足这个公式的时候,系统就达到了平衡。

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。
