Stochastic resonance of linear harmonic oscillator subjected to simple harmonic force with frequency fluctuation
具有频率涨落的简谐力激励下线性谐振子的随机共振

In view of the situation that the linear harmonic oscillator is subjected to the simple harmonic force with the frequency fluctuation, we work out the expression of the first-order moment for the system response. It is found that the system output response vibrates at the natural frequency, that the response amplitude shows bona-fide stochastic resonance as the simple harmonic excitation force frequency varies, and that the suppression and the resonance appears as the natural frequency varies.
