In this study, we simulate breath figures that are evolving two-dimensional assemblies of droplets on a substrate. We focus on the Voronoi/Shannon entropy of these figures, which quantifies the order related to the coordination number of droplets. We show that the Voronoi entropy of the complete breath figure pattern converges to a value that is the one of a randomly distributed point system. Conversely, the subset containing exclusively large droplets of the breath figure exhibits significantly lower entropy than that obtained for all droplets. Using molecular dynamics simulations, we show that coalescence events in breath figures induce the same Voronoi entropy as that caused by repulsive interactions in a bidimensional atomic system.
在本研究中，我们模拟了在基底上由液滴构成的二维演化组装体——呼吸图。我们关注这些图形的Voronoi/香农熵，它量化了与液滴配位数相关的有序性。我们表明，完整呼吸图图案的Voronoi熵收敛到一个值，该值与随机分布的点系统的值相同。相反，仅包含呼吸图中大液滴的子集表现出的熵明显低于所有液滴的熵。通过分子动力学模拟，我们表明呼吸图中的聚并事件所诱导的Voronoi熵与二维原子系统中排斥相互作用所引起的相同。
