噪声对三势阱系统混沌性质的影响

本文研究了在两种不同信嗓比的复合激励作用下，三讲系统的物理性质。通过概率密度函灵数及平均相轨线的分析，指出该系统在这两种情况下作所谓的混沌随机运动。

Influence of Noise on Chaotic Behaviourof Three-well System

In this paper, the physicsal behaviour of the three-well system under the combined excitation withtwo different signal noise ratios is investigated. Through the analysis of their probability density func-tion and mean trajectory, it shows that this system in these two cases can occur chaotic stochastic mo-tion.
