The analysis of the size distribution of droplets condensing on a substrate (breath figures) is a test ground for scaling theories. Here, we show that a faithful description of these distributions must explicitly deal with the growth mechanisms of the droplets. This finding establishes a gateway connecting nucleation and growth of the smallest droplets on surfaces to gross features of the evolution of the droplet size distribution.
对在基底上凝结的液滴(呼吸图案)的尺寸分布进行分析是对标度理论的一个检验。在这里,我们表明,要对这些分布进行准确的描述,就必须明确地处理液滴的生长机制。这一发现为连接表面上最小液滴的成核和生长与液滴尺寸分布演化的宏观特征建立了一个通道。
