中文摘要：

协调结构(CS ) 的空间时间的进化为骚乱控制是重要的并且拖减小。在 CS 之中，低、高的速度条纹结构显示出典型爆炸现象。分析基于一个时间系列三维、三部件(3D-3C ) 速度扁平的板回答 Tomographic 和解决时间的 PIV (Tomo TRPIV ) 测量的狂暴的边界层(TBL ) 系统。用多决定小浪变换和有条件的采样方法，我们提取了内在的拓扑学并且发现条纹结构出现在像酒吧的模式。而且，我们抓住了地点和短暂 CS 的速度信息，然后基于空间时间的跨关联的扫描计算了 CS 的繁殖速度。这在相关动力学性质上为进一步的研究打了一个基础。

英文摘要：

The spatial-temporal evolution of coherent structures （CS） is significant for turbulence control and drag re- duction. Among the CS, low and high speed streak structures show typical burst phenomena. The analysis was based on a time series of three-dimensional and three-component （3D-3C） velocity fields of the flat plate turbulent boundary layer （TBL） measured by a Tomographic and Time-resolved PIV （Tomo TRPIV） system. Using multi-resolution wavelet transform and conditional sampling method, we extracted the intrinsic topologies and found that the streak structures appear in bar-like patterns. Furthermore, we seized locations and velocity information of transient CS, and then calculated the propagation velocity of CS based on spatial-temporal cross-correlation scanning. This laid a foundation for further studies on relevant dynamics properties.
