Cooperative two-phase eutectic growth under an oscillating thermal pull rate. Alternating alpha and beta lamellae adjust interphase spacing along the advancing solidification front through lateral fault glide, tilt bifurcations, and solute boundary layer diffusion. 双相共晶层状生长与相界断层漂移。
The advancing solidification front cuts straight across the lower terrace, freezing solute into alternating α- and β-stripes. 灰烬在拉伸的热场中结晶，相界并非静止，而是随着抽拉速率的脉动发生侧向滑移与剪切分叉。Where two fault lines collide, a dark vacancy is trapped forever in the stone.
Coupled Jackson-Hunt spacing dynamics with an oscillating velocity boundary condition $V(t) = V_0 (1 + A \sin(\omega t))$. When pull velocity accelerates, the local interphase spacing $\lambda$ falls below the critical limit $\lambda_{JH}$, forcing lamellar termination; deceleration forces lamellar pinch-off and tilt bifurcation. 采用一维相界坐标数组向后方光栅化推进，成功还原了金属共晶凝固中相界位错的侧向攀移（fault glide）。The motion delta (0.418) reflects the periodic clearing of fault cascades.
