分叉的

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。

The active region of a TV line is identified by the high time interval of BLN.

Finally,the buckling,bifurcation and stability of the Timoshenko beam is analyzed near the critical load through numerical calculation.

通过数值计算，分析了弹性Timoshenko梁在临界载荷处的屈曲和分叉以及稳定性，并与理论值进行了比较。

Optical fiber communication is transferring form point-to-point transmission to mesh network. Traditional optical-electronical-optical transformation limits the data rate and adds the cost. With reconfigurable optical add/drop multiplexer for signal switching and routing, the OEO transformation can be bypassed, reduceing equipment size and cost.
