摘　　要：利用三心定理、几何和极限理论首次证明导杆机构的滑块绕机架与滑块的绝对瞬心的角速度等于导杆转动的角速度，并建立了新公式。为求导杆机构各点的速度带来了简便易行的方法理论。In this paper,the author demonstrates that the angular velocity of absolute instant center between the slide block of slide bar around the rack and the slide block equals to that of the revolving slide bar by making use of the three core theorem,geometry and ultimate theory.A new formula is established which provided a simple and practical theoretical method for deriving speed at different points of the slide bar mechanism.
