There's the water phase, there's the ice cube is the solid phase, and there's some water, gas, vapor, and that's one bar.

里面放一块冰，这是固态；,于是我们得到了水，冰和水蒸气三态共存的点。

You need to know if it's an equilibrium, and you also need to know how many components you have in your system So, a glass of ice water with an ice cube in it, which is a heterogeneous system, has only one component, which is water, H2O.

要知道它是不是平衡的，你还需要知道,你的系统中有多少组分,一杯放了冰块的水，虽然它是个非均匀系统，但它只有一种组分，那就是水。
