The discussion about the moving charges with circular motion in the uniformity magnetic field 在匀强磁场中带电粒子作圆周运动的讨论
This principle may be applied to circular motion as well as to motion in a straight line 这条原则不仅应用于直线运动，而且可运用于圆周运动。
This is a mechanism using a slider to transit a rotation to reciprocating the linear motion skimpily 此机构利用一滑槽，即可简单的将圆周运动转成直线的简谐往复运动。
When the car moves along the orbit , the axis of the two unparallel shafts point to the center of the circle orbit 非平行轴使得小车作圆周运动时两轴的中心线指向圆心。
A pedal or lever operated by the foot for circular drive , as in a potter ' s wheel or sewing machine 踏板一种由脚操纵带动圆周运动的踏板或杠杆，如制陶者的陶车或缝纫机的踏板
Size reduction is attained by shearing stress and pressure , which are generated by high torques at the crushing roll 在由破碎轧辊长距进行缓慢圆周运动时所产生的压力和切力的
Both men had just begun to swim towards the shore , when they noticed with dismay that the speed - boat was moving in a circle 这两个人刚刚开始向岸边游去，这时他们突然惊愕地看到快艇正在作圆周运动。
And the mass of black ball will also change to keep in the same radius . if you click the right mouse button and drag it updownleftright , 此时球的大小（或质量）将会随之改变，以维持在同样半径作圆周运动。
The tension in your arm provides exactly the force needed to cause your body to move in a circle and therefore to stay on the ride 手臂的张力正好提供了使身体做圆周运动所需的力，所以你才能停留在木马上。
