Crystallization 结晶
✏ atom - 原子
✏ molecule - 分子
✏ lattice - 结晶
✏ dissolve - 溶解
✏ saturation point - 饱和点
✏ saturation solution - 饱和溶液
Crystallization can be defined as the process through which the atoms/molecules of a substance arrange themselves in a well-defined three-dimensional lattice and consequently, minimize the overall energy of the system. When a substance is subjected to crystallization, its atoms or molecules bind together through well-defined angles.
On adding a solid substance in a liquid and stirring it, the solid dissolves in the fluid. But when added more and more solid to the liquid, a point comes after which no more solid dissolves in the liquid. This point is called a saturation point and the fluid is called a saturation solution.
结晶的过程是物质的原子/分子以规定好的三维晶格形式排列的过程，这样系统的总能量最小化。当物质结晶时，其原子或分子通过特定的角度结合在一起。
在液体中加入固体物质并搅拌，固体就溶解在液体中。但是当液体中加入越来越多的固体时，会达到一个点，固体不再溶解到液体中，该点称为饱和点，该液体被称为饱和溶液。
