摘要:
我们推导了时间平均稳态能量共振频率的精确表达式,并表明该频率可由振幅共振频率与速度共振频率的算术平均值极好地近似。此外,我们论证振幅共振频率可被视为能量共振频率,因为它给出了瞬时能量的最大峰值。
英文摘要:
We derive the exact expression for the resonant frequency of the time-averaged steady-state energy and show that this frequency is excellently approximated by the arithmetic mean of the amplitude and velocity resonant frequencies. In addition, we argue that the frequency of the amplitude resonance can be regarded as the energy resonance frequency, since it provides the maximal peak values of instantaneous energy.
