Explanation
When a system composed of a large number of atoms or molecules reaches equilibrium under certain external constraints, one or more uniform regions of mutual recognition are formed within the system. A uniform region with the same composition, structure, and properties constitutes one. A system that contains only one is called a single system or a homogeneous system; A system with multiple components is called a complex system, and there must be clear interfaces between them.
