【Abstract】 Fluctuation complexity is used to ananlyze time series of pressure signals in the gas-solid fluidized bed. It is more easy to calculate than the maxium Lyapunov exponent. The trends of fluctuation complexity changing with gas velocity and height are concluded. Moreover the axial distribution of fluctuation complexity is compared. In this study, the initial characters of fluidized bed are rudimently discussed from the point of view of complexity theory.更多还原
