许多实验产生多尺度形态，这些形态在某些长度尺度上是光滑的，而在其他长度尺度上是分形的。关于形态学特性的准确陈述，例如，由相关函数和结构因子得到粗糙度指数、分维、畴尺寸、界面宽度等。在本文中，我们提出了两个系统的结构因子数据：（a）液滴在液滴形态的两相分离的混合物;和（B）基态形态在稀反铁磁体。散射数据的一个重要特征是非Porod尾，它与粗糙域和界面的散射有关。图形摘要
Many experiments yield multi-scale morphologies which are smooth on some length scales and fractal on others. Accurate statements about morphological properties, e.g., roughness exponent, fractal dimension, domain size, interfacial width, etc. are obtained from the correlation function and structure factor. In this paper, we present structure factor data for two systems: (a) droplet-in-droplet morphologies of double-phase-separating mixtures; and (b) ground-state morphologies in dilute anti-ferromagnets. An important characteristic of the scattering data is a non-Porod tail, which is associated with scattering off rough domains and interfaces.Graphical abstract
