  1. ( 2 ) the liman problem is normally adopted to check the liability of numerical method. the calculation error was within 9 % by comparison with the theoretic solutions of liman problem in the following case, the dimensionless calculation length was 2 with high pressure zone 0. 8, and the dimensionless state parameters were p1 = 2, p2 = 1, p1 = p2 = 1, u1 = u2 = 0. experiment results in literature [ 8 ] were used to check the adaptability of the numerical model developed here for unconfined gas cloud explosions and the calculation error was within 13 %

    ( 2 )數值方法的可靠性通常用黎曼問題的解析解檢驗,本文以無量綱計算區長度為2 ,高壓區長度為0 . 8 ,狀態參數為p _ 1 = 2 , p _ 2 = 1 , _ 1 = _ 2 = 1 , u _ 1 = u _ 2 = 0條件下的黎曼問題解析解對所編制的爆炸場計算程序進行了考核,結果表明該程序的計算誤差在9以內;為考核本文計算模型預測開敞空間氣雲爆炸的適用性,以文獻[ 8 ]的實驗數據進行了校核,計算誤差在13以內。
  2. The edc cracking reaction rate is higher in the wall zone and reaches a maximum at 0. 3 of dimensionless length of reactor coil

    表明確定最優的爐管管徑時必須考慮提高裂解速率與降低結焦速率之間的平衡。
  3. In this paper, the theory for lateral vibration of pile foundation with consideration of shear deformation of pile is established, and the influence of the ratio of pile length to its diameter, the ratio of pile stiffness to soil stiffness and dimensionless frequency were studied systemically

    本文建立了一整套考慮樁體剪切變形的樁基水平振動分析理論,並較系統地研究了樁的長徑比、樁土剛度比、激振頻率等因素對樁基水平動力響應的影響。
  4. By using the solution developed and the frequency - dependent stiffness coefficient and damp coefficient, the dynamic behavior, especially the one concerned with the variation of the dimensionless maximum response along the depth, for the pile with finite length or with infinite length was studied. it was shown that to simplify computation a pile of finite length can be taken as the one of infinite length if the ratio of pile length to its diameter ( i. e. lid ) is greater than 15

    利用所得解,採用與頻率相關的剛度系數和阻尼系數的近似表達式,對有限長樁和無限長樁的動力特性特別是對最大無量綱響應沿深度的變化曲線進行了參數研究,表明在常見樁土參數下,當長徑比大於15時,可將有限長樁視為無限長樁以簡化計算。
