    Abstract: 本研究主要目的為量測拍撲翼機構之環流量。內容包括拍撲機構之設計、翅膀之設計以及翅膀材料之選擇與實驗架設、追蹤粒子之選擇和PIV系統的操作。
    The circulation of flapping wing in this research was measured by Particle Image Velocimetry (PIV) system. The flapping mechanism was designed to reduce the flapping phase differences between left and right wings.
    The vortices generated around the wing in flapping period were recorded using high speed camera. Leading edge vorices and trailing edge vortices produced in flapping upstroke and downstroke. The radius of vortex and the strength of vorticity and circulation were increased in wing span direction.
    According to the results of the experiment, circulations measured varied according to the phase angle and getting stronger away from the root. Lift and thrust increased from the mechanism to the wing tips by circulation’s generated.
