柱塞气－ 液－ 固并流上行系统表现出占据全部管截面的气栓段和气液固混合段间隔出现的流动结构。本文通过标准统计方法（ 功率谱） 和非线性混沌分析方法从定性和定量两方面证明了气栓和气－ 液－ 固混合段运动都是混沌运动。气栓运动的混沌动力学参数（ 相关维和Ｋｏｌｍｏｇｏｒｏｖ 熵） 明显比气－ 液－ 固混合段运动的小，从理论上表明描述气栓运动的动力学比气－ 液－ 固混合段运动的动力学简单，可预测度明显要大。文中还讨论了较精确确定重建伪相空间滞时的方法。
Piston gas-liquid-cocurrent up-flow system showed the flow structure appearing at the interval between gas-liquid-solid mixing section and the gas-liquid-solid mixing section which occupied the whole pipe cross-section. In this paper, we prove that the motion of gas plug and gas-liquid-solid mixing segment are both chaotic by qualitative and quantitative methods through standard statistical methods (power spectrum) and nonlinear chaos analysis. The chaotic dynamics parameters (correlation dimension and Kolmogorov entropy) of the gas-bolt motion are obviously smaller than those of the gas-liquid-solid mixing section, and theoretically indicate that the kinetics of describing the gas-plug motion is lower than that of the gas-liquid- Simple, predictable significantly larger. The paper also discusses a more accurate method to determine the reconstruction of pseudo-phase space hysteresis.
