Stuart vortex chain and shear layer roll-up in a stratified boundary. Streamline reconnection and filament strain fields under cyclic acoustic forcing. 剪切层在周期性声学激励下的涡核缠绕与应变拓扑。
The shear boundary runs west-northwest across the upper terrace, dividing two ash currents moving at unequal velocities. 界面在周期性声学微扰下失稳卷曲，凝固成一列自锁的猫眼状涡核。Between the cores, thin filaments of soil are drawn out into stable, unmixing separatrices.
Modulated a Stuart vortex chain with an orthogonal acoustic standing wave to induce periodic streamline reconnection. 鞍点处的流线重联极易在字符离散采样时退化为斑块，改用局域主应变率标量映射字符权重后，边缘活性稳定在 0.499，清晰保留了涡丝拉伸拓扑。Density variance remained tight at 0.0016 across all twelve inspection phases.
