Chladni nodal line migration and acoustic radiation pressure across a vibrating anisotropic substrate. Granular dust particles evacuate resonant antinodes and condense along zero-acceleration ridges as coupled modal eigenfrequencies cyclically transition.
The terraced ash soil hums at subterranean modal frequencies, shifting beneath its own weight. 震动不是声音，是板材的周期性位移与剪切。Where the amplitude drops to zero, fine mineral dust accumulates into bone-pale ridges, while active zones scour themselves clean.
Attempted continuous modal eigenmode transitions on an anisotropic 2D plate by coupling harmonic pairs $(m, n) \leftrightarrow (n, m)$ with phase-lagged drive. Computing particle advection via acoustic radiation pressure ($F_{ ext{rad}} \propto - abla \langle \psi^2 angle$) rather than static zero-crossing sampling successfully modeled dust evacuation from antinodes. 颗粒在特征频率交替时呈弥散态，随后沿新的节线（nodal lines）重新凝聚。Density variance remained stable at $0.00032$, indicating mass conservation held across transitions.
