确定性混沌理论为描述流化床的非线性动力学行为提供了有用的定量工具，而复杂性理论的发展为有限序列的评价提供了一种新的方法。本文利用混沌参数和复杂性测度对反应器内压力脉动信号的非线性、流体力学行为进行了研究，并通过多尺度分析得到了一致的结果，进一步揭示了气固两相系统中压力脉动信号的非线性、流体力学行为。
Deterministic chaos theory offers useful quantitative tools to characterize the non-linear dynamic behavior of a fluidized bed and the developed complexity theory presents a new approach to evaluate finite sequences. In this paper,the non-linear,hydrodynamic behavior of the pressure flutuation signals in a reactor was discussed by chaos parameters and complexity measures.Coherent results were achieved by our multi-scale analysis,which further exposed the behavior in a gas-solid two-phase system.
