Based on the above discussion and a great quantity calculation, the lock-in region of the flow about the oscillating cylinder was obtained.

在以上讨论和大量计算的基础上，本文最后给出了振动圆柱绕流的锁定区域。

Digital particle image velocimetry (DPIV) was applied to investigate the flow field around a circular cylinder undergoing sinusoidal oscillating movement in still water.

本文用数字粒子成像测速仪(DPIV)，对圆柱体在静水中作正弦振动而产生的振荡流场进行了实测研究。
