间歇式高速摄影机在抓片与定片过程中,胶片的运动特性与抓片爪的运动特性并不完全一致。详尽的分析胶片的运动特性发现,胶片除被抓片爪抓动以外,尚存在四种“附加位移”。 Intermittent high-speed camera in the process of grasping and fixed films, the film’s movement characteristics and grasping the claw movement characteristics are not exactly the same. A detailed analysis of the motion characteristics of the film reveals that there are four “additional displacements” apart from the film being gripped by the gripper.
