摘　　要：采用美国PASCO公司研发的PASCO数字化实验系统为实验平台,对“跳环”实验现象进行研究;利用PASPORT新型传感器对实验中原线圈电流、感应线圈电流同步进行数据采集及分析,结果为原线圈电流与感应线圈电流的相位差为π/2~π;并对原线圈电流、感应线圈电流图像与线圈运动状态进行了对比分析.The phenomenon of the computer-aided ＂link jumps＂ experiment is studied by using the PASCO digitization experiment system developed by American PASCO Corporation as the platform of the experiment. According to analysis of the data gathered from electronic current in original coil and induced electronic current by the new type sensor PASPORT, it is obtained that the phase difference between electronic current in original coil and induced electronic current changes from π/2to π. The movement state of the coil is studied by comparing with the image of electronic current in original coil and induced electronic current.
