| 摘 要： | 本文根据奇异吸引子细胞模型理论，定性解释了混沌频谱的基本特征，与仿真结果一致．结果表明，奇异吸引子的频谱是连续或分段连续的并具有若干个主峰，连续的频段则是由随机变化的键频率所引起，而后者是混沌频谱的主要特征．

| Abstract: | Based on the cell model theory of strange attractors, this paper qualitative explains the basic features of chaotic spectrum, which is corroborated by simulation results. It is shown that the spectrum of strange attractors is continuous or piece_wise continuous and has some obvious peaks, and that the continuous frequency bands are caused by the randomly varied bond frequencies. The latter is the main feature of chaotic spectrum. |
