描述了两个耦合的非线性电子电路中各自能够表现出极限环振荡的延时诱导振幅死亡的实验观察。建立了耦合相同振子在耦合强度和时延参数空间中存在多个连通的死亡岛。这些区域的存在早在理论基础上就被预测到了[物理学]。Rev. Lett. 80,5109 (1998)；物理（阿姆斯特丹）129D, 15（1999）。实验还揭示了多频态的发生，随着时间延迟的增加，振荡的频率抑制，同相和反相集体振荡的发生。
Experimental observations of time-delay-induced amplitude death in two coupled nonlinear electronic circuits that are individually capable of exhibiting limit-cycle oscillations are described. The existence of multiply connected death islands in the parameter space of coupling strength and time delay for coupled identical oscillators is established. The existence of such regions was predicted earlier on theoretical grounds [Phys. Rev. Lett. 80, 5109 (1998); Physica (Amsterdam) 129D, 15 (1999)]. The experiments also reveal the occurrence of multiple frequency states, frequency suppression of oscillations with increased time delay, anti the onset of both in-phase and antiphase collective oscillations.
