  3. According to the data of the covariance - stationary stochastic time series, we can get the state space modeling algorithm quickly and stably by singular value decompositi on and orthogonal projection. this algorithm will be faster and more stable

    在已知平穩隨機時間序列樣本數據的情況下，論述了如何採用正交投影演算法和正交奇異值演算法建立隨機時間序列的狀態空間模型和狀態矢量估計，這種數學建模方法對于船舶機艙中的系統數學建模有很大的幫助
  4. The approaches, which have been applied in the modeling and analysis of energy demand at up to now, are based on the traditional modeling technology. there is an important assumption that time series data is stationary in the traditional modeling technology

    目前，應用於能源需求建模與分析的方法通常是以傳統建模技術為基礎的，而傳統建模技術有一重要前提，即所處理的時間序列數據是平穩的。
  5. Granger received the nobel prize, because their cointegration theory had solved two difficult problems, the time - varying volatility and non - stationary in the time series analysis field. in this paper, will introduce the normal knowledge of cointegration theory, and emphatically depict the possibility of applying cointegration algorithm to condition monitoring and fault diagnosis for engineering systems, which are non - stationary processes. it is well known that non - stationary system behavior causes grave difficulties on system modeling and condition monitoring due to the time - dependent statistics
