The basicflows are computed by a low-dimensional Galerkin method.The results confirm thattwo times global mode switching occur with increasing Re up to which the Hopf bifur-cation occurs when the absolutely unstable region cover the whole reversed flow region,and the first explanation of this phenomenon with absolute/convective instability theoryis given.

结果证实了只有当绝对不稳定性区域完全覆盖了回流区才会形成整体的Hopf分叉，此前随着Re数的增加整体模态经历了两次跳跃；并首次用绝对/对流不稳定性理论解释了这一现象。
