| 摘 要： | 研究非高斯非平稳噪声背景下非线性系统在微弱周期信号摄动下的混沌动力学行为，仿真过程证明被噪声污染的微弱周期信号使混沌系统的动力学行为变化很小；非高斯非平稳噪声对周期运动的影响较为明显。研究了微弱周期信号和非高斯非平稳噪声信号联合摄动下的混沌运动特征。

| Abstract: | This paper researches the non - linear system movement perturbated by weak signal under non - gaussian＆non -stationary noise environment. The simulation result shows that the non - gaussian ＆ non - stationary noise has little effect on the non - linear system movement when it is on chaotic state ; While much effect on for non - gaussian ＆ non - stationary noise. This paper mainly researches the chaotic special movement character under the perturbation of noise and weak period signal. |
