| 摘 要： | 用电子线路模拟的方法对Ｄｕｆｆｉｎｇ系统进行随机共振实验研究，发现在一定条件下可通过改变阻尼系数获得较高输出信噪比ＲＳＮ，理论上得出大阻尼条件下系统的输出信噪比，并将理论与实验结果进行了比较。

| Abstract: | The stochastic resonance (SR) is investigated by experiments using an electionic circuit siniulating Duffing system. ft found that a high output signal-to-noise rate (SNR) canbe obtained by varying damping parameter under certain conditions. Applying the theory of adiabatic approximation,the output SNR is obtained analytically considering the existance of large damping.The theoretical predictions are compared with the experimental results. |
