摘　　要：课题组采用蒙特卡罗数值模拟的方法对简谐噪声驱动的双稳系统进行研究和分析,该系统是取消了小周期信号的仅有简谐噪声驱动的双稳系统。研究结果发现:通过简谐噪声不同参数的调节可以人为控制系统的类相干共振现象,这一研究不仅丰富了非线性动力学的理论,也为类相干共振的实际应用提供了理论的支撑。The research group used Monte Carlo numerical simulation to study and analyze a bistable system driven by harmonic noise,which is a bistable system driven only by harmonic noise without small periodic signals.The research results found that the quasi coherent resonance phenomenon of the system can be artificially controlled by adjusting different parameters of harmonic noise.This study not only enriches the theory of nonlinear dynamics,but also provides theoretical support for the practical application of quasi coherent resonance.
