摘　　要：有关延迟反馈(Delayed Feedback)的研究已经在混沌控制、天体动力学和神经系统等领域中受到了非常广泛的关注.首先阐明了研究整个复杂网络的一条有效的途径——网络基本单元,接着阐明了复杂网络中一种十分常见的基本单元——反馈环(Feedback Loop),然后将时间延迟与反馈结合起来,通过一个具体的模型进行数值模拟,进而分析了延迟反馈在随机系统中的重要作用.The research on the delayed feedback has been concerned by many scientists in more and more fields,such as chaos control,astrodynamics,nervous system and so on.Firstly,the network motif which is an effective method to study the whole complex network is put forward.Then,feedback loop which is a very common unit in the complex network is clarified.In addition,the time delay and the feedback are taken into account,and through the simulation of the prototype model,the important roles of the delayed feedback in the stochastic system are analyzed.

关 键 词：延迟反馈 网络基本单元 反馈环 随机系统
