H A Danimation-attributes.md13 动效设计的时长单位一般使用毫秒（ms）表示，1秒=1000毫秒。在帧率（FPS）60帧的环境下，1帧=16.67毫秒。
203 每秒钟显示的帧数即帧率（FPS）。由于人眼的特殊生理结构，所看画面帧率一般高于每秒约10~12帧，就会认为是连贯的，该现象为视觉暂留。但连贯不代表感知流畅，运动较快的动画需要更高的帧率来保障流畅度。
205 相同时间和位移距离情况下，不同帧率效果对比（90FPS和120FPS受浏览器播放器的限制，可能无法看出差异）。

219 …（如操作引导动画）的帧率要求没有交互类动效那么严苛，早期迪士尼的手绘动画基本帧率是24FPS，也能满足观看流畅的程度。高帧率的动画则拥有更细腻的视觉体验，特别是针对快速类的动作，细腻度尤为明显。有…
