The deducing process and the results all show that using phase rule to analyze the thermodynamic characteristics of multiple phase equilibrium system is necessary.

推导过程和结果都说明，在进行多相平衡体系的热力学分析时，以相律为指导是必要的。

So, that's a homogeneous system, one phase. You have to know if your system is an equilibrium system or not.

所以这是个均匀系统，只有一个相，你得知道你的系统,是不是个平衡系统。
