摘　　要：运用混沌分析的方法,分析浆态鼓泡床反应器的压力信号,表明浆态鼓泡床反应器在不同操作条件下都具有混沌性,并且在不同固含率的条件下,最大Lyapunov指数变化显著,说明固含率对混沌特性有显著的影响。在实验条件下,浆态鼓泡床系统作Hurst分析,表明时间序列具有“持久性”,意味着过去增加或减少的趋势,将在未来一定时间内持续进行。The pressure signal of the slurry bubble column reactor is analyzed. The slurry system is a chaos system under various operation conditions. The largest Lyapunov exponent changes notability in different solid concentration, which expresses that the solid concentration has dramatically affections on chaos. The slurry system is analyzed by Hurst methods under experimental condition. The time series has ＂permanence character＂ which means trend of increasing or decreasing in the past will go on in the future.
