Inside the box, the scientists created a trail with their artificial fish, which was essentially a rubber fin on a stick that created a trail similar to the swimming motion of a real fish.
在那个盒子里，科学家用假鱼设计了游动轨迹，基本上，那是由橡胶鱼鳍形成的，和真正的鱼游轨迹十分相似。
An arc motion would make people's gaze stick to the curving hand and stay there, while a straight line would make their eyes flick back to the beginning and jump between the two.
弧形移动能使人注视弯曲的手并在移动终止点集中注意力，但直线移动会让人目光闪回起始点，并在两点间移动。
When system is in stick-slip motion, the system response can be periodic, quasi-periodic and chaos with the change of pulling velocities, system stiffness and viscous.
当系统发生粘滑运动时，系统响应随激励速度、系统刚度及阻尼的变化而呈周期、拟周期及混沌运动交替变化的形式。
Players may use any part of the cue stick to move the cue ball, including the tip, but not with a forward stroke motion.
