摘要
一个半径为R和R的大圆盘和一个小圆盘并排在一起，以1.33 Hz的频率重复交换位置。这项动议是模棱两可的。如果r/ r r/ r > 0.8，观察者感知到两个静态磁盘在反相中膨胀和收缩，磁盘之间的间隙没有运动。观测者对质心的运动做出反应，当r/ r时反应最大
A large and a small disk with radii R and r , side by side, exchange positions repetitively at 1.33 Hz. The motion is ambiguous. If r/R< 0.8 then observers perceive a single large disk jumping back and forth across a small static disk. But if r / R> 0.8, observers perceive two static disks that expand and contract in counter phase, with no motion across the gap between the disks. Observers respond to the movement of the centroid, which is greatest when r/R< 0.8.
