  1. The acceleration is first evaluated from governing equation, secondly, the formulae of displacement and velocity are developed basing on some assumptions, and then the discrete expressions of the response mean square value are deduced

    首先，直接從控制方程出發計算加速度，其次，給出了位移和速度的一種近似計算公式，最後，推導出響應均方值的離散計算表達式。
  2. The factors, especially the interval, that affect the statistic mean wind velocity are expatiated. then the effects on the power spectrum of pulsating wind pressure as well as on the dynamic response of the structure under wind loads are analyzed by means of monte carlo method when the square item of pulsating wind velocity is ignored

    在分析了平均時距對統計平均風速影響的基礎上，進而以結構的可靠度為指標利用montecarlo方法分析了當平均時距比較大時，脈動風速平方項對脈動風壓功率譜的影響。
  3. Spectral method and spectral element method are both used in the present dns. the flow is developed from an initial velocity field whose mean and root mean square values are fitted to the experimental data. the reynolds number of the flow is 2250 based on the mean velocity and the radius of the pipe

    本文在空間離散上採用譜方法和譜元法的結合，通過在圓管層流速度剖面上疊加隨機擾動作為初始場的方法，計算了管長為，平均雷諾數為2250的光滑圓管內的湍流流動，建立了圓管內較低雷諾數下速度場和壓力場的數據庫。
