研究了两个排斥耦合洛伦兹振子的幅值依赖耦合对振子死亡（OD）的影响。数值模拟结果表明，当振幅相关耦合的约束强度发生变化时，振荡状态可能发生向OD状态的过渡。理论上确定了OD域的参数形式，与数值结果吻合较好。建立了一个电子电路，以显示具有振幅相关耦合的向OD状态的过渡过程。这些发现对混沌控制和抑制振荡具有实际意义。
The effects of amplitude-dependent coupling on oscillator death (OD) are investigated for two repulsively coupled Lorenz oscillators. Based on numerical simulations, it is shown that as constraint strengths on the amplitude-dependent coupling change, an oscillatory statemay undergo a transition to an OD state. The parameter regimes of the OD domain are theoretically determined, which coincide well with the numerical results. An electronic circuit is set up to exhibit the transition process to the OD state with an amplitude-dependent coupling. These findings may have practical importance on chaos control and oscillation depression.
