摘　　要：在中学物理教学中,老师们通常会播放动画或视频进行辅助教学,降低学生的理解难度。但是,现在应用于辅助教学的动画或视频制作难度较大且缺乏交互性。通过拓展动态几何的几何约束到逻辑约束,提出了适用于物理学科的逻辑动画系统概念,并基于可缩放矢量图形(SVG)实现了物理逻辑动画的制作和播放。该系统降低了物理辅助教学动画的制作和修改难度,并增强了动画的交互性。In middle school course, animations and videos are often used by teachers for assistance, so that students＇ difficuhies in understanding are reduced. However, animations or videos applied on auxiliary teaching are difficuh to make and lack of interactivity. By extending dynamic geometrical constraint to logical constraint, a new concept of logical animation system that meets the needs of physics teaching was proposed, and based on Scalable Vector Graphics （ SVG）, producing and playing physical and logical animation were achieved. This system simplifies producing and modifying animations in physics auxiliary teaching, and enhances the interactivity of animations as welh
