本研究探讨了沉淀模式的形成条件下，内部电解质分布不均匀。根据所施加的浓度梯度，各种新的沉淀结构，如分叉段，萌芽模式，和Liesegang环分离与破环已被观察到。分析表明，尽管存在外加浓度梯度，但第n个沉淀带的位置Xn与其形成时间tn仍满足简单的规律，但当介质中出现断环时，沉淀带的间距（Xn+1/Xn）不再是线性关系。
This study explored precipitation pattern formation under conditions where the inner electrolyte was inhomogeneously distributed. Depending on the imposed concentration gradient, various new precipitation structures such as bifurcated segments, budding patterns, and Liesegang rings segregated with broken circles have been observed. The analysis illustrates that, despite the presence of an imposed concentration gradient, the location of Xn of the nth band and its time of formation tn still satisfy a simple law, but the spacing (Xn+1/Xn) of the precipitation bands departs from a linear relationship once broken rings are developed in the medium.
