flapping frequency

基本解释

Is every bird flapping its wings at the exact same frequency?
每衹鳥會以同樣的頻率扇動翅膀嗎？

High speed digite vedio and image processing were used to analyze the effects of the non-dimensional velocity and the flag aspect on its kinematics, flapping frequency and amplitude.

Therefore, the main characteristics of this system is a high accuracy, breadth to adjust soon scope, high just a restrict for, and system accuracy primarily suffering construction flapping frequency.
可見，本系統的主要特點是高精度、寬調速範圍、高剛度，而且系統精度主要受結搆諧振頻率的限制。
