Bridges dendritic solute rejection into periodic reaction-diffusion precipitation dynamics. Outward electrolyte flux crosses an oscillating supersaturation threshold, nucleating concentric Liesegang bands that buckle under convective shear and coarsen via Ostwald depletion halos.
East of the dendritic bed, the seeped electrolyte does not freeze into branches; it waits for the front to oversaturate. 灰土吸饱了卤水，在蒸发与毛细剪切的拉扯下，凝成一圈圈同心的沉淀环。The ground hardens into rhythmic bands, each ring starving the stratum immediately behind it.
Coupled radial electrolyte diffusion with an oscillating nucleation product threshold $c_A c_B > K_{sp}$. Once nucleation triggers, the precipitating sink starves the adjacent ring halo, reproducing the Jablczynski spacing law before convective shear buckles the outermost waves. Density settled cleanly at 0.287 with edge activity at 0.577. 析出环没有散开，奥斯特瓦尔德熟化（Ostwald ripening）成功在点阵中撕裂出锐利的贫化同心带。
