摘要
本文探讨了导数重构法在实际应用中所存在的问题 ,提出了针对性的改进措施 ,使之能很好地用来揭示系统的混沌特征。改进导数重构法在循环流化床中的应用揭示了循环流化床中絮状物运动的混沌特征 ,为流化床混沌研究提供了一个有效的工具。
The problems existing in application of derivative reconstruction method were discussed in this paper. Some measures were taken so that the improved method can be efficiently used to reveal the chaotic characteristics of systems. Furthermore, the improved derivative reconstruction method was applied to chaotic study of the circulating fluidized bed. The chaotic characteristic of the cluster motion in the circulating fluidized bed was also revealed. Thus the improved derivative reconstruction method will provide a more efficient tool for chaotic study of fluidized beds.
