最近引起广泛关注的两种增长机制与单一统计力学模型有关。当一种流体推入另一种粘度较高的可混溶流体时，会发生没有界面张力的尖端分裂。当各向异性分子聚集时，就会发生枝晶生长——一个常见的例子是雪花。我们发现这两种结构都是分形对象，并且可以从单个统计力学模型中获得，这意味着所涉及的基础物理过程之间存在关系。
Two growth mechanisms of considerable recent interest are related to a single statistical mechanical model. Tip splitting without interfacial tension occurs when a fluid pushes into another miscible fluid of higher viscosity. Dendritic growth occurs when anisotropic molecules aggregate-a common example is the snowflake. We find that both structures are fractal objects, and can be obtained from a single statistical mechanical model, implying that there is a relation between the underlying physical processes involved.
