- The downflow and horseshoe vortex is guided to the downstream successfully far away from the bridge pier structure. 向下射流与马蹄形涡流成功的被导引至桥墩结构物下游后方处。
- Furthermore, the horseshoe shape vortex system occurred to the upstream of the jet exit and the layer structure of vortexes occurred to the wake of the reverse flow region downstream of the jet are also investigated. 另外，观测到射流喷口上流的马蹄涡系以及射流逆流区下游尾迹区旋涡的层状结构形式。
- By comparison with different distances between endwall fence and stator pressure surface, it is found that the control effect on horseshoe vortex is optimal at shortest distance. 通过距离压力面位置远近不同的3个翼刀方案的比较，发现距压力面愈近的翼刀方案控制二次流的效果较好。
- Two methods of open -end or break spinning are in use: rotor spinning and fluid or air or vortex systems. 目前采用的开端纺纱或叫自由端纺纱的方法有两种：气流纺纱和流体(或空气,或涡流)纺纱。
- The horseshoe vortices become appearing until the multiple jets merging into a new jet.As the shear-layer vortices break, the CVP forms. 在多孔射流中，当多股射流合并为一股新的射流之后，才出现马蹄形涡的雏形，并最终发展成为马蹄形涡；
