Designing of BF-1 rotors depends upon the principle that the total damping is equal to zero at the point near the stall flutter boundary.
文中提出了实验模型的零阻尼设计原则，描述了失速颤振发生的过程。
If the total time is increased, then there is less need for a significant amount of damping window to be applied to the collected time data.
如果总时间增加了，那么就不那么需要对采集的时域数据施加大的阻尼窗了。
The damping effect of the honeycomb can reduce the influence of the inlet preswirl on the total temperature difference.
