  1. According to the fluctuating property of wind, on the stochastic vibration finite element theory, some calculation formulas of the response, including the along - wind response and the across - wind response, are obtained, the ideology of the torsion vibration in the double - tower structure and the ideology of the double - tower structure ' s dynamical wind load are also put forward at the same time. by using the stochastic vibration module of the general finite element program, the paper analyses the performance of the wind resistance more deeply and fully, discussing the influence on the double - tower structure from the diversification of the different component. the variance law of dynamic displacement and wind - induced vibration coefficient is derived through analyzing structure stochastic vibration, so is the effect of several parameters on dynamic displacement, acceleration and wind - induced vibration coefficient

    從結構風振的基本理論出發，通過對脈動風功率譜的分析，推導了結構風振響應（順、橫風向）的計算公式，同時提出了雙塔結構的扭轉振動和動力風荷載計算的思想，在結合通用有限元程序的隨機振動模塊的情況下，對雙塔結構的抗風性能作了深入、全面研究，探討了雙塔結構構件截面的變化對其抗風性能的影響，同時探討了順風向風速譜的選取、風速、參與計算的振型數、風與結構耦合作用是否考慮等因素對分析結果的影響，比較了規范風振系數的計算與隨機演算法結構的異同，並討論了原因，得出一些有意義的結論。
  2. Under the background of target tracking in high - density clutter, the calculation formula of the pda algorithm ' s error variance is analyzed and revised firstly, and the modified pda ( mpda ) is derived, which not only improves the tracking performance, but also makes the error variance and the real error of the algorithm match well

    針對高密度雜波環境中的目標跟蹤問題，首先分析和修正了pda演算法中誤差方差的計算公式，提出了修正的pda演算法（ mpda ） ，它不僅提高了跟蹤性能，而且使得誤差方差與演算法的實際誤差能夠很好地匹配。
  3. This paper finds out the mean value and variance of load sequence in a period of time based on statistics and then works out the bias ratio of every point in load sequence using corresponding calculation formula and at the same time compares it with threshold value so that " unhealthy data " can be removed and accurate and effective load forecasting can be ensured

    本文利用統計學的方法，求出某段時間內負荷序列中的均值與方差，再利用偏離率的計算公式計算出負荷序列中每一點的偏離率，並與閾值相比較，從而除去「不良數據」 ，為準確有效地進行負荷預測提供了保證。
