Interfacial precipitation of silver halides in water-swollen polymer films occurred in complex, multilayered patterns if the concentrations of counterdiffusing reactants were unequal or decreased at different rates. Development of the rapidly forming Liesegang rings, which extend the phenomenon of periodic precipitation to the submicrometer range, is attributable to the combined effect of a moving reaction zone and periodic immobilization of colloidal silver halide.
如果扩散反应物的浓度不同或以不同的速率降低，水合聚合物膜中的卤化银会发生界面沉淀，形成复杂的多层图案。快速形成的李萨如（Liesegang）环的发展将周期性沉淀现象扩展到亚微米范围，这归因于移动反应区和胶体卤化银的周期性固定的综合影响。
