摘　　要：频闪照相技术能直观便捷地展现物体的运动特征,在物理教学中的使用越来越普遍.以自由落体运动为例,用数码相机高速拍摄运动物体的频闪照片,然后利用Getdata Graph Digitizer等图像分析软件能从这些频闪照片中迅速准确地提取运动过程的详细数据,以便于利用计算机软件对该运动特征进行定量分析,可以显著提高实验教学课堂效率.The stroboscopic photography is able to intuitively and easily display the movement of objects,and thus is more and more widely used in physics teaching.In case of free-fall motion,it is very quick and efficient to access the information of the motion process in strobe photos taken with digital cameras via the image analysis software such as Getdata Graph Digitizer,which can facilitate the quantitative analysis of the movement of interest,and thus greatly improve the teaching efficiency in class.
