摘　　要： 针对数值仿真中仿真步长对连续混沌系统吸引子性态和仿真速度的影响,分析连续混沌系统序列穷尽过程,计算其穷尽熵,画出穷尽熵随步长的变化曲线图,得出数值仿真实验中步长的最佳选取范围,进一步推导出步长选取的界限公式。三个连续混沌系统的数值仿真实验证明了此方法的有效性。 In view of the influence of step size on the property and form of continuous chaotic attractors and siknulation speed in simulation, the exhaustive process of chaotic sequence was analyzed, then exhaustive entropy of the sequence was computed and the chart of exhaustive entropy to simulation step size was plotted, fmally the best range of simulation step size was obtained. The formula of the range was also given. The method was proved valid by simulation of three continuous chaotic systems.
