振子受迫振动的振幅和能量的时间依赖性

On Time Dependence of Oscillation and Energy of a Forced Oscillator

本文讨论了振子受迫振动的振幅和能量的时间依赖关系。结果表明，初始静止的振子在外力作用下能量和振幅随时间的增长而增大，一般情况下将趋于一个稳定值，该稳定值及其趋于稳定值的速率和强迫力提供的功率及阻尼损耗有关。对无阻尼振子的共振，振子的振幅和能量无限制地增加，振子不能达到并且也不存在稳定状态。

This paper is discussed on the dependent relations between times and oscillation or energy of a forced oscillator.As a result,the oscillation and the energy as increases as times and in general,will be reached a stablite state.This value and velocity re1ative to forced power and damper consume For undamped resonance,oscillation and energy will increas boundlessly,and stablile state as well no reached as a1so no existed.
