摘要: 在混沌科学领域,截至目前混沌吸引子随机性强弱还没有一个统一的评判标准,文章尝试提出了一种判别混沌随机性强弱的原理和算法,且该方法不需要相空间重构。应用该方法对周期运动、强弱混沌、两种离散混沌映射及噪声进行数值仿真,结果表明该方法能有效识别不同混沌运动的随机性强弱。

Abstract: In chaos scientific domain,there has been no common criterion about the strength of random characteristic of chaotic attractors up to now.In this paper,a principle and an algorithm about that are proposed,and the method doesn’t need phase space construction.Then the method is applied to simulate the periodic motion,the strong and weak chaos,two kinds of discrete map and white Gaussian noise.The result shows that the method is valid to identify the strength of random characteristic of different chaotic motions.

Key words: random characteristic, chaos, Logistic map, Henon map, white Gaussian noise
