    "差旋+黏滞扩散：环状/亚环结构的方位与径向漂移由 `Ω_K(R)` 与有效黏滞 `ν` 控制；非对称性主要来自初始相位与局部密度梯度。",
    "螺旋密度波/RWI：压力极值与涡度极值触发亚环（sub-ring）与涡旋，产生 `m` 模漂移；非对称由波-流相互作用与局部声速变化引起。",
    "Lense–Thirring 进动/盘扭曲：几何进动改变“回响环/等时延环”的照明与视向，导致滞后图（lag map）中环下结构的扇区漂移。",
    "照明几何与反射：冠层高度/形态变动（lamppost/扩展冠层）改变反射与回响强度分布；能依赖相位可重排但难以长期维持显著非对称漂移。",
    "传播系统学：能带拼接、反射成分建模与响应变化对漂移速度与相位中心造成偏置。"
