  1. In this dissertation, we firstly prove that any dirichlet problem is indeed equal to a voltages problem of networks. we give five solutions to dirichlet problem in two dimensions ; among these five solutions, we prove that the iteration solution and the solution of relaxations are exponential convergence, then we estimate their respective convergence rates ; secondly, we discuss random walks on general networks, prove that there is an one to one correspondence between networks and reversible ergodic markov chains ; thirdly, we give probabilistic interpretation of voltages for general networks : when a unit voltage is applied between a and b, making va = 1 and vb = 0, the voltage vx at any point x represents the probability that a walker starting from x will return to a before reaching b ; furthermore, we study the relationship between effective resistance and escape probability : starting at a, the probability that the walk reaches b before returning to a is the ratio of the effective conductance and the total conductance

    本文證明了任何邊值的dirichlet問題都可轉化為求解電路電壓的問題：給出了計算平面格點上dirichlet問題的5種方法：證明了迭代法和松馳法都是指數收斂的，並分別給出收斂速度的估計；討論了一般電路上的隨機徘徊，驗證了電路與可逆的遍歷markov鏈是一一對應的；給出了電路電壓的概率解釋：當把1伏電壓加於a ， b兩端，使得v _ a = 1 ， v _ b = 0時，則x點的電壓v _ x表示對應的markov鏈中，從x出發，到達b之前到達a的概率；進一步地，給出了逃離概率與有效電阻之間的關系：從a出發，在到達b之前到達a的概率為有效傳導率與通過a的總傳導率之比。
  2. I. a mtil ( iaxial elastic - plastic hardening - sofling constitutive model of concrete is proposed iii order to offer a nonlinear material model of concrete for space restoring force analysis of reinforced concrete members taking into account the softening behavior of concrete. the concrete material model is incorporated the elastic - plastic hardening fracturing constitutive model of concrete with the plastic - fracturing theory of concrete, modified without defining two loading functiomis, and based on five parameter power function failure criterion proposed by guo zheng - hai etc from tsingliua ( jniversity, or three parameter unified strength theory proposed by yu mao - hong from x ian iiaotong university

    1 、將砼彈塑性硬化斷裂本構模型與塑性斷裂理論結合起來，並加以改進，但無需定義兩個加載面，以清華大學過鎮海建議的五參數冪函數或以西安交通大學俞茂宏建議的，參數統一強度理論作為砼的強度破壞準則，建立了砼多軸彈塑性硬化松馳本構模型，能為鋼筋砼構件空間恢復力分析提供砼非線性材料模型，並能反映砼材料的軟化段。
  3. Through the strong pulling tests of four kinds of synthetic fiber filter cloth, the mechanical performance index of the filter cloth in dry and wet conditions were measured, the influence of various pulling speeds on the fracture strength and the fracture tensile rate of the filter cloth was derived. it was concluded that the stress of the filter cloth could relax when it was beyond the yield point

    通過4種合成纖維濾布的強力拉伸試驗，測得了濾布在干、濕兩種狀態下的力學性能指標，得出了不同拉伸速度對濾布斷裂強度和斷裂伸長率的影響，同時指出當濾布的應力超過屈服點時，會出現應力松馳現象。
  4. In contrast to existing simplex method, this method has several peculiarities as follows : to begin with, applying it to solve linear programming problem. one need n ' t introduce any additional variable such as relaxing variable, artificial variable and other parameters, so that calculation is subtracted on a large scale. in addition to this, as a result of its higher degree of structuralization, this algorithm can be more easily transformed into program language and, of course, more quickly performed by computers

    與現有的單純形法相比，新演算法具有如下主要特徵：第一，求解過程不需要引進諸如松馳變量、人工變量等參變量參與運算，計算量大大減少了；第二，新演算法較單純形法的結構化程度高，更容易轉化為程序語言，進而在計算機上更快地得以實現；第三，新演算法在運算過程中不會引起攝動現象。
