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。

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

结果表明，富锌相的存在使得合金溶解加速，溶解较为均匀。

The result shows zinc enrichment phase makes alloy dissolve accelerative and uniformly.

这也从分形理论的角度证明了在超塑性固相焊接头的形成过程中，焊接面各微区的焊合状态是非均匀性的。

It is proved by fractal theory that the welded state of every micro zone at welded surface is uneven in the formation process of isothermal superplastic solid-state welding joint.

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

You're going to have to know when you describe the system, if your system is homogeneous, like your coffee with milk in it, or heterogeneous like water with an ice cube in it So heterogeneous means that you've got different phases in your system.

你要知道,当你描述一个系统时，你的系统是均匀的呢，像掺了牛奶的咖啡，那样还是非均匀的，像放了冰块的水,非均匀系统就是说,在你的系统中有不同的相存在。
