Frank-Oseen nematic director field governed by six topological disclinations with zero net winding sum. Spatial schlieren textures emerge from splay-bend elastic energy dissipation, periodically contracting into core singularities. 液晶缺陷编织与向列相弹性形变场的周期性呼吸。
The ash terrace here forms a thin birefringent film, where molecular orientations lock into six topological pins. 六个向角缺陷在正交偏光下自旋互锁，把弹性应变折叠成明暗相间的施利伦刷（schlieren brushes）。When the subsurface cools, the braided lines breathe inward, pinching the lattice into singular dark knots.
Relaxed the Frank-Oseen director field over six topological charges ($s = \pm 1/2$) constrained to zero total winding number. Mapping crossed-polarizer intensity $I = \sin^2(2 heta)$ directly produced acceptable schlieren geometry, but brush boundaries blurred during periodic phase breathing. 引入局部弹性畸变模量加权后，向列相的展曲（splay）与弯曲（bend）能量耗散在字符密度上形成了清晰的梯度，核收缩时密度均值稳定在 0.274。
