摘　　要：在正弦波驱动的非线性漂移波中,每一个模式都有与驱动波共振的参数区,驱动波能量的馈入引起共振负能模式向正能模式转变,这个转变与相应参数区中系统发展双稳态有关。In the nonlinear drift-waves driven by a sinucoidal wave, every mode has a resonance regime correspondingly in the parameter space of the driving frequency and strength. Feeding of the applied wave energy causes the transition of a resonant negative-energy mode to positive-energy one. This transition is relevant to the development of bistability of the system in the corresponding regime.
