| 摘 要： | 介绍一个非常有趣的物理演示实验——振转耦合振子实验.弹簧振子实际上是一个具有两个振动模式的振动系统,两振动模式之间存在着耦合,振动能量将从一种模式向另一模式转移.在共振条件下可以实现能量在两模式之间的来回完全转移.

| Abstract: | An experiment of a moving-turning oscillator is introduced.It is shown that a spring-mass oscillator is a system of two modes,and there is coupling between the two modes,the vibration energy will transfer from one mode to the other.The energy can be transferred entirely when their vibrating frequencies are equivalency,i.e.,resonance coupling. |
