Efflorescence refers to crystallized salt structures that form at the surface of a porous medium. The challenge is to understand why these structures do not form everywhere at the surface of the porous medium but at some specific locations and why there exists an exclusion distance around an efflorescence where no new efflorescence forms. These are explained from a visualization experiment, pore-network simulations and a simple efflorescence growth model.
结晶盐结构在多孔介质表面形成的现象称为“结露”。问题在于，为什么这些结构不是在多孔介质表面的所有地方形成，而是在某些特定位置形成，以及为什么在结露周围存在一个排除距离，在这个距离内不会形成新的结露。这些问题可以通过可视化实验、孔隙网络模拟和一个简单的结露生长模型来解释。
