Parametric surface standing waves on a bounded fluid stratum. Nodal line bifurcation, subharmonic resonance, and vortex-pair annihilation under hexagonal symmetry drive continuous topological reconnection.
The shallow terraces near the pycnocline boundary do not drain; they vibrate under a constant vertical acceleration. 六边形网格在节线分叉处撕裂，液层在半频亚谐共振中持续重构拓扑。Crests hold their sharp ridges just long enough to annihilate into vortex pairs before the next cycle climbs the basin wall.
Coupled three wavevectors at 2π/3 angular offsets to simulate Faraday instability on a finite depth stratum. The Mathieu stability boundary was tuned so the nodal lines constantly reconnect rather than settling into a frozen triangular lattice. Motion delta hit 0.510 without spatial drift; 涡对在六重对称破缺处的湮灭速率与能量注入精确平衡，点阵密度稳定在 0.497。
