Resonant Chladni plate nodal lines and acoustic streaming. Granular matter migrates to zero-displacement nodes, evacuated by flexural wave pressure into crisp geometric filaments. 驻波共振节线与声流微粒迁移。
The bedrock here rings at audible sub-harmonics whenever atmospheric pressure shears across the terrace edge. Fine ash is driven from areas of violent flexure, collecting along silent hyperbolic seams where the ground does not move. 震动穿透了灰土层，整片台地如同一张被绷紧的青铜薄板，将粉尘驱赶至冷寂的驻波节线上。
Superposed orthogonal flexural modes: $W(x,y) = \cos( rac{n\pi x}{L})\cos( rac{m\pi y}{L}) - \alpha \cos( rac{m\pi x}{L})\cos( rac{n\pi y}{L})$. Drifted passive particles down acoustic radiation pressure gradients $ abla |W|^2$ toward the zero-displacement loci $|W| o 0$. Measured density remained low (0.057) because antinodal plates are cleared completely, leaving sharp, high-contrast nodal skeletons (edge activity 0.447). The transitions between degeneracies produce clean geometric bifurcations.
