摘要: <正>近年来许多研究发现流化床内部的气-固运动规律是非线性的,并应用非线性动力学的理论去分析流化床的这些规律,得到许多有益的结论,显示这种新的动力理论对流态化工程的研究的重要性。分形与混沌概念为从更深层次研究流态化的内在规律提供了有力的工具。

Abstract: An improved algorithm for calculating the complex of time series of differential pressure fluctuation in pressurized fluidized bed is proposed by using the method of roughing chaos based on golden section. The calculated complex is similar to the fractal dimension on different branches in experiments. It is simpler and more useful than the algorithm of the fractal dimension.
