常规的记录物体运动轨迹的方法中有的比较繁琐,不适合随堂演示,有的对实验条件要求较高。针对上述问题,设计出了基于利用智能手机“轨迹拍照”功能轨迹记录实验方法,实现了在随堂演示实验中对运动轨迹进行记录和重现的功能。 Conventional method of recording the trajectories of objects in some of the more complicated, not suitable for demonstrations, and some require higher experimental conditions. In view of the above problems, the function of recording and reproducing the motion track in the demonstration of the pupil is designed based on the experimental method of using the track record of the smartphone “track camera ”.
