基于包含驱动和阻尼的三波非线性相互作用模型, 构建了一个描述高能量粒子测地声模(EGAM)与Dimits区漂移波湍流相互作用的系统, 并在系统的线性增长及非线性振荡阶段分别进行了解析和数值研究. 更进一步的数值结果表明, 在忽略EGAM的贡献时, 该系统具有随着线性驱动/阻尼率等参数的变化, 从极限环振荡经历倍周期分岔最终进入混沌的行为特征.在此基础上, 形式上构建了本系统的非线性饱和Dimits区, 并研究了EGAM对Dimits区漂移波的影响. 结果表明, 对于不同幅度和频率的EGAM, 被调制后的漂移波将表现出受到激发或抑制的效果. 对此, 采用相空间分析的方法给出了相应的解释.Based on the nonlinear three-wave interaction model including driving and dissipation, we construct a system to describe the nonlinear interaction between energetic particle induced geodesic acoustic mode (EGAM) and the drift waves turbulence in the Dimits shift region, and study both analytically and numerically the linear growth and nonlinear oscillation phases of the system, respectively. Further numerical results show that, without the contribution of EGAM, the system goes through limited cycle oscillation to period doubling, and finally route to chaos with the change of the linear drive/dissipation rate. On this basis, the nonlinear saturated “Dimits region” of the system is constructed, which is then used to study the influence of EGAM on the drift wave in the Dimits region. The results show that for EGAM with different amplitude and frequency, the modulated drift wave can be either excited or suppressed, partly reproduces the results from large scale simulation. Finally, We use the method of phase space analysis to give the corresponding explanation.
