  6. What the practical problems is often gotten is a single variable time series which has a time interval of t, reflect by a lot of interactive physics factor, containing the mark of all variates participating in movement, traditional time series analysis is to analyse going from this array to the form directly it ' s time develops, one dimension analysis loses useful information, the characteristics of phase space reconstruction method is to construct one dimension scalar quantity to high dimension vector, prop the geometry space of the state, show all dynamical information of system in phase space. the characteristic that just constructs again according to the phase space in this text, analyse the time series of responding, use the relevant knowledge of symbol dynamics and reconstruct phase space, put forward a kind of relation degree analysis method of the systematic mathematics model which has theory basis, so reach the correction of calculation mathematics model, make it accord with the actual systematic state

    實際問題中常常得到的是一個時間間隔為t的單變量的時間序列,它是許多物理因子相互作用的綜合反映,蘊藏著參與運動的全部變量的痕跡,傳統的時序分析是直接從這個序列去形式地分析它的時間演變,一維分析必然喪失許多有用信息,相空間重構方法的特點是把一維標量數據構造成高維矢量,支起狀態的幾何空間,在相空間中展示系統全部動力信息。本文正是根據相空間重構的特點,對響應時間序列進行分析,利用符號動力學、重構相空間等方法,提出一種有理論依據的系統數學模型關聯度分析方法,從而達到修正計算數學模型,使其更符合實際系統狀態的目的。
