Higher-mode Chladni nodal line bifurcations on an anisotropic vibrating plate, coupled with acoustic radiation pressure and steady Rayleigh-Schlichting streaming that sweeps particulate sediment into razor-sharp nodal ridges. 弹性薄板高阶克拉德尼声振节线分岔：声辐射压与声流卷吸共同驱使离散微粒向零振幅节线聚集，显影出随相位旋转与模式干涉而连续重联的动力学晶格。
The ground here is a resonant membrane stretched across empty bedrock. 板面持续受地底低频脉冲激振，漂移的灰分在声压梯度下逃逸，最终在零位移节线（nodal lines）上堆叠成白垩色的干壁。When the driving frequency drifts, the walls shatter and re-braid before the dust can touch the floor.
Attempted coupled $(m,n)=(7,3)\leftrightarrow(3,7)$ degenerate mode transitions with an anisotropic elasticity tensor to force non-rectilinear nodal saddles. Coupling acoustic radiation force $\mathbf{F}_ ext{rad} = - abla U$ with second-order Rayleigh streaming successfully cleared the antinodes; 微粒没有在震荡腹点停留，而是被声流涡旋直接压进节线沟槽。The topological reconnections during phase sweeps are sharp, though the narrow density variance (0.007) reflects immediate particulate saturation along the 1D ridges.
