摘　　要： 在用穷尽熵计算混沌序列类随机性强弱的基础上,提出了k错穷尽熵的定义,并证明了它的两个基本性质,然后用此方法分析了三种常见连续混沌系统:Lorenz系统、Rssler系统和Chua’s系统的类随机性的稳定性。仿真结果表明,此方法能反映连续混沌系统的随机本质;而作为随机源,Chua’s系统比Lorenz系统和Rssler系统更好。 The notion of k-error exhaustive entropy was proposed,based on exhaustive entropy.It was used to measure the strength of random-like property of chaotic sequences,and its two basic properties were proved.Then the method was used to analyze the stability of random-like property of three common continuous chaotic systems,such as Lorenz system,Rssler system,and Chua＇s system.The simulation results show that the approach can reflect the random essence of continuous chaotic system and Chua＇s system is better than Lorenz system and Rssler system as the source of randomness.

关 键 词： 连续混沌系统 类随机性 稳定性 错穷尽熵
