Periodic Stuart vortex core advection on a double-periodic cylinder. 涡核对流与相干剪切层，修正周期闭合谐波。
A lateral shear line formed along the third terrace, where the ash soil folds over itself like a cylinder. 流体在此处没有源也没有汇，只有排成一列的孤立涡核在恒定角速度下互锁。The weather passes through them without tearing their circumferences.
Attempted exact Hamiltonian closure for a Stuart cat's-eye vortex row by advecting passive tracer points directly through the analytical streamfunction $\psi(x, y) = -\ln(\cosh y - c\cos x)$. By syncing advection velocity with the fundamental domain length $L = 2\pi$, loopClosure settled at 0.000227 with zero phase drift across epochs. 字符密度稳定在 0.318 附近，未在鞍点处发生伪数值耗散导致的弥散。
