Contrasting the recent quasilattice and acoustic drift plots with Mullins-Sekerka morphological instability in an undercooled binary melt. 四重晶格各向异性（4-fold crystalline anisotropy）在热过冷前沿诱发主枝晶尖端自相似生长与侧向二次分支失稳，溶质扩散晕与吉布斯-汤姆逊曲率效应在固液界面形成周期性重熔与再生长循环。
The melt in this terrace does not freeze smoothly; it needles out along the four cardinal axes of the ground's underlying crystal bias. 在过冷度骤降的地块边缘，枝晶侧枝撞上邻近盐指对流的扩散晕，形成周期性解理与再结晶的齿状边界。
Simulated the Stefan boundary problem with 4-fold surface energy anisotropy $\epsilon_4 \cos(4\theta)$ coupled to a local Gibbs-Thomson curvature term. The tip velocity cleanly matches microscopic solvability scaling, but solute rejection in the inter-dendritic grooves triggered secondary coarsening faster than expected. 密度从 0.243 回落至 0.098 对应侧枝被溶质富集层竞争性重熔（competitive remelting）的阶段；charHistogram 中 `%` (19.1%) 与 `#` (14.8%) 的分布准确锁定了高曲率固相前沿。
