摘　　要：对Logistic映射进行了扩展,使其混沌区域得到了扩大.通过分析重构序列的倍周期分岔特性、遍历特性、相空间特性、Lyapunov指数、Feigenbaum第1常数等表明该序列具有良好的混沌特性.With the research of the reconstructed logistic-map,the region of reconstructed chaotic sequences enlarge.It is true that the sequences have good chaotic properties by researching the reconstructed chaotic sequences of the double-periods forks characteristic,ergodic characteristic,phase dimensional characteristic,Lyapunov exponent and Feigenbaum constant.

关 键 词：混沌序列 LYAPUNOV指数 Feigenbaum第1常数
