  1. The stress - strain curve of new - old concrete and hprrc, are suggested to be modeled by two sections : the ascending section of the stress - strain curve is simulated by cubic parabola equation and the descending section is simulated by rational fraction, where the theoretical value is in good agreement with the test value. the research results also provide a theoretical basis of earlier stage for improving crack resistance of new - old concrete interface

    新一老硅及hprrc應力一應變全曲線建議採用兩段式擬合:上升段採用三次拋物線方程模擬，下降段採用有理分式模擬，理論值與試驗結果吻合較好。該研究成果為新老混凝土結合面抗裂能力的提高提供了前期的理論基礎。
  2. In this paper, we consider mixed finit element methods for the initial - boundary value problems of two order hyperbolic equations and linear integro - differential equations of parabolic type, obtain the error estimates of the discrete schemes for this two kinds of problems. in chapter one, we consider the expanded mixed finite element methods for the followling 2nd order hyperbolic problems this method expands the standard mixed formulation in the sense that three variable are explixitly treated : the scalar unknwon, its gradient and its flux

    本文討論了二階雙曲方程和線性拋物型積分微分方程方程初邊值問題的混合有限元方法，得到了這兩類問題混合有限元離散格式的誤差估計。第一章討論二階雙曲初邊值問題的擴展混合元方法。該方法能同時逼近未知函數、未知函數的梯度和流體的流量，較好的模擬了帶有混合型邊界條件的二階雙曲問題。
  3. According to testing results, the stress - strain curve of the cemented soil stabilized the nanometer silica fume is fitted using a quadratic parabolic curve and expression equation for upward sector of the stress - stra in curve is given

    根據試驗結果，分析了納米硅粉水泥土的變形特性，並對其應力應變曲線進行了二次拋物線擬合分析，推導了曲線上升段的表達式。
  4. An extended hyperbolic mild - slope equation, which can take such terms as wind input, bottom friction and nonlinearity of wave into account, here has been deduced into a parabolic one in the form of a series of governing equations described with complex amplitude. it became a complete wave model when integrated with corresponding physical and imaginary ( open ) boundaries, and can be solved through the improved crank - nicholson or the well known alternating direction implicit ( adi ) difference method, both of which can accelerate the convergent speed, expand limitation of the mathematical method and improve the quality of the solution

    本文基於綜合考慮底摩阻、風能輸入及非線性影響的推廣雙曲型緩坡方程，將其進行轉換，產生一個演變方程，其復振幅控制方程為拋物線性，並採用adi差分格式、改進的crank - nicholson格式及相應的物理和虛擬（開）邊界條件進行求解，以提高數值模擬的適用性、數值計算的穩定性、收斂速度及精度。
  5. Used dynamics equation to express the relation between the accumulation amount of no 3 - n leaching and time : urea, ammonium - bicarbonate and composed fertilizer can be expressed as equation yt1 / 2 = a + bt, complex mixed fertilizer can be expressed as equation 1 / y = a + bl / t. the accumulation leaching quantity of no 3 - - n with urea, ammonium - bicarbonate, composed fertilizer and complex mixed

    隨時間t的變化用方程進行擬合，結果表明ck 、碳按和復混肥處理，以雙曲線方程l / y二a + bl八擬合效果最好，而尿素和復合肥處理則以拋物線方程y ， 』 / 2 = a十bt擬合效果最好。
