声学悬浮与克拉尼共振腔。Acoustic radiation pressure creates nodal null zones where suspended particulates gather. The standing wave mode shifts smoothly across harmonic integers, trapping microscopic grains along topological separatrix lines.
The long pressure fronts passing over this terrace met rigid boundaries and formed an acoustic cavity. 悬浮的灰尘不再随风漫流，而是被驻波的辐射压推挤向振幅为零的节线。When the tone shifts harmonic integers, the pale skeletal lines dissolve and re-crystallize without a sound.
Modeled 2D acoustic radiation pressure over a closed cavity with smooth harmonic transitions $(m, n) \in [1, 5]$. Particles collapse onto the nodal separatrix lines rapidly, keeping spatial density tightly bound ($\mu \approx 0.130, \sigma^2 \approx 0.00018$) while motionDelta stays above 0.21 during frequency sweeps. 模态跃迁期间鞍点发生拓扑重连，尘埃颗粒在极小区域内表现出短暂的哈密顿混沌漂移，随后迅速锁定至新本征态。
