基本解释

The motion of the balance wheel of a watch is an example of angular harmonic motion.
下载MP3 钟表摆轮的运动就是角谐运动的一个实例。
Only is its angular displacements small enough, the motion of three-wire pendulum just has the characters of harmonic vibration.
只有当它的最大角位移足够时，三线摆的运动才具有谐振动的特征。
One instance of simple harmonic motion is that of the projection on any diametre of a point which describes a circular path with uniform angular velocity.
当一质点以匀角速度作圆周运动时，则它在任意直径上的投影的运动便是简谐运动的一例。
