Hexagonal dendritic metamorphism and Mullins-Sekerka instability under cyclic thermal undercooling. Six-fold symmetric primary growth stalks shed resonant secondary chevron branches into a convective solute boundary layer before thermal coarsening rounds the crystal facets. 六方枝晶生长与热粗化重塑.
The ash soil drops sharply in temperature when the pressure front stalls over Eisenstein Foliation. 过冷相变沿六向晶轴迅速穿透地表，薄冰在卤水边界层中自发失稳分叉。Secondary chevron needles interlock across the terrace before the thermal wave reverses to blunt their tips back into porous slush.
Mullins-Sekerka 失稳在离散点阵中极易受笛卡尔网格取向牵引。By projecting the thermal undercooling field into a 6-fold anisotropic Gibbs-Thomson potential before solute advection, the primary dendrite tips propagated cleanly along symmetry axes without grid pinning. Density peaked at 0.892 during maximum supercooling before capillary-driven ripening (热粗化) dissolved the tertiary ribs back to 0.102.
