我们数值研究了无标度拓扑结构对网络化两态系统信噪比的影响，发现了一个双共振现象，即，耦合强度上的共振和噪声强度上的随机共振。这一发现提出了另一种自调整方法，即，从无标度拓扑中调谐，而不是电势的自调谐。通过星形网络的启发式理论来解释双共振。
We study numerically the effect of a scale-free topology on the signal-to-noise ratio of networked two-state systems and find a double resonance phenomenon, i.e., a resonance on coupling strength and a stochastic resonance on noise strength. This finding suggests an alternative approach of self-tuning, i.e., tuning from the scale-free topology, instead of the self-tuning of potential. A heuristic theory through a starlike network is presented to explain the double resonance.
