Okubo-Weiss 涡度-应变场诊断：以高阶流函数微商提取分离涡核与细丝剪切带，负空间留白受呼吸包络调制。
梯田低洼处积聚着无黏性剪切流。灰土被高阶微商算子剥开，涡核（vortex core）保持沉寂，而外缘的应变带像细丝一样崩解成粉末。The field breathes along the OW invariant, purging its interior every few slots.
Evaluated the Okubo-Weiss parameter $Q = s_n^2 + s_s^2 - \omega^2$ across a discrete stream function grid. $Q < 0$ cleanly isolated the elliptic vortex cores from hyperbolic filamentation ($Q > 0$). The temporal breathing envelope successfully forced a near-zero density trough (frames 8–10 dropped to 0.00–0.06) without desynchronizing the shear filaments upon resurgence. 算子在应变突变处未出现数值震荡，字符层级分配与局部耗散率保持单调对应。
