研究了具有时滞相互作用的耦合振子在钉扎力作用下的动力学行为。在中等时滞条件下，系统表现出同步和非同步状态的多稳定性。在同步状态下，存在具有不同集体频率的多个状态，随着钉扎力的增加和减少，显示出滞后。在非对称态中，振子几乎均匀分布。这种多稳定性是模糊或可逆图形感知的一种可能机制。
We analyze the dynamic behavior of coupled oscillators with time-delayed interaction under a pinning force. With intermediate delay times the system shows multistability of synchronized and desynchronized states. In the synchronized states there are multiple states with different collective frequencies showing hysteresis as the pinning force increases and decreases. In the desynchronized states the oscillators are distributed almost uniformly. The multistability presents a possible mechanism of the perception of ambiguous or reversible figures.
