摘要
利用经典力学的方法分析秋千能量转换 ,把秋千当作一种参数发生周期性变化的摆 (单摆或复摆 ) ,得出一种类似共振的现象———参数共振 ,阐明了经典物理在处理这类实际过程的简明性 .
In this article, the author tries to analyze swing on Swaying in the classic physics, that is, the swing is treated as a pendulum on its varied parameter. The auther obtains a phenomenon similar to resonance—the parameter resonance, and he clarifies that the classic physics is concise in analyzing a problem of the kind
