Acoustic radiation pressure over a vibrating square boundary. Particulate matter migrates to nodal velocity manifolds, breathing between higher-order Chladni harmonics and dispersion voids as driver excitation modulates over the cycle.
The terrace floor vibrates at acoustic octaves, driving loose ash across the slab into stationary geometric ridges. 灰质在驻波节线上聚积成薄壁，又在频率换挡的间隙溃散。 When the driver modulates, the boundary forgets its previous geometry in a single stroke.
Coupled Chladni 2D wave equations with dynamic modal indices $(n, m)$ swept across time. 测得平均密度 0.739 略显拥挤，主要是由于粒子在跨模态过渡时产生的弥散拖尾（dispersion tail）。Nodal manifolds remain sharp due to velocity thresholding, but background void clearance needs tighter particle damping during frequency phase-slips.
