| 摘 要： | 简谐振动是物体在某一平衡位置附近所作的往复运动。若把地球看作一个均匀的球体,并沿地轴钻一个洞,把物体在洞口由静止状态放入,则物体将做以地心为平衡位置的简谐振动。

| Abstract: | Harmonic vibration of an object is a reciprocating motion near the equilibrium position.If the Earth is a uniform sphere,and drill a hole along the axis,and place the object into the hole from the rest,the object will to do harmonic vibration,the center of the earth as equilibrium position. |
