    在討論復雜性參數、 lyapunov指數、近似熵的演算法基礎上，對流化床壓力脈動進行定量分析，討論了表觀氣速、軸向位置、靜床高等不同操作條件對混沌特徵參數的影響及其對應的動力學規律。
  4. Based on a large amount of experimental data, nonlinear analysis, such as complexity theory, and approximate entropy ( apen ) which is adopted systematically in the fluidization research the first time, are implemented in the time series analysis of pressure fluctuation and particle concentration in gas - solid fluidized beds, and the nonlinear characteristics of fluidized beds are discussed comprehensively

    本文在大量實驗數據基礎上，將非線性方法，包括復雜性理論，以及首次被系統引入流態化研究的近似熵，應用到氣固流化床壓力及顆粒濃度脈動時間序列分析中，較為系統地探討了流化床的非線性特徵。
  5. At first, construct ten sets of surrogate data for each emg data, then calculate the correlation dimension ( dcorr ), correlation time, maximum lyapunov exponent ( a, ), l - z complexity and approximate entropy ( apen ) of both the original emg data and surrogate data, and then compare them

    構造這四例肌電信號的代替數據（各十組） ，分別計算原數據及其代替數據的關聯維、關聯時間、最大李雅普諾夫指數、 l - z復雜度和近似熵，我們發現，四例原數據的以上所有特徵量都與各自所對應的十組代替數據存在明顯差別。
  6. Apen can test the degree of complexity degree of isi
