  1. There are three difficulties and key problems in this papaer : : the first problem is what is the dominance bearing of the leakage fractures, and how the bedrock fracture water distribute, the second is how to test the complex chemical behavior in experiment way and quantify the relative parameters, the last question is how to number the transportation of the element 90sr and its pollution to solve the three problems, this paper does lots of work and come to the prospective order, the creativities in this thesis as follow : ( 1 ) the dominance bearing of the leakage fractures and the distribution feature of the fracture water are ascertained based on rich geological data, these basal researches are very important, which are the premises to build the transport model of the fracture water in hae field

    本項研究工作的難點和關鍵問題有三個： hae處置場基巖裂隙系統中，導水裂隙的優勢方位是什麼，基巖裂隙水活躍帶分佈情況如何；怎麼對核素遷移的復雜化學行為進行實驗室測試並取得有關定量化參數；怎樣數值化表現出溶質的遷移行為和污染情況本論文在解決以上三個問題上做了大量的工作，達到了預期的目的，其創新之處有以下三點： （ 1 ）通過地質資料的分析，首次提出了hae預選處置場基巖裂隙導水的優勢方位和基巖裂隙水活躍帶的大致分佈特徵。它是一個很重要的基礎性研究成果，是建立hae處置場水運動模型的前提。
  2. As the automobile industry ’ s growing, more and more aluminum alloys have used in the manufacturing of automobile and aluminum alloys replaced parts of steel planks used in automobile parts which is one of the key resources for light weighting of automobiles. but as aluminum alloys have some limitation in forming such as crinkle, fracture and difficult for welding, the industrial scale of aluminum alloys is limited

    隨著汽車產業的發展，鋁材在汽車上的用量迅速增加，鋁合金取代部分鋼材成形汽車零件已經成為解決汽車輕量化的關鍵手段之一，然而由於鋁合金在傳統的沖壓成形中會出現難以消除的裂痕和褶皺，以及深沖性能比較差、焊接難度高等特點，使得鋁合金的大規模運用受到限制。
  3. In this paper a numerical method for equations of transport and biodegradation in the fractured media is discussed. because the equations consist of terms related to advection, diffusion, biochemical as well as the term of exchange betwen the fracture and the porous media, it is very difficult to find their solution. in order to find more efficient method for solving these equations, several numerical methods for the equations without biochemical terms are discussed first. the numerical results show that the cubic spline method can be used to solve advection flow dominated problem which often occurred in the fractured media. then, the equation with both advection - diffusion term and biochemical term are discussed. the splitting - operator is used to decouple the advection and diffusion terms with biochemical term in the equations. the way to determine the smaller time step for solving fast biochemical terms is introduced through comparing the order of characteristic time of biochemical term with that advection ( diffusion ) term. numerical simulation results show that good agreement between analytical solution and experiment result is attained

    本文討論了含裂隙介質地下水污染物輸運與生物降解非線性方程組數值求解方法.方程含有對流項、擴散項、生長、死亡、吸附、解吸、趨化和孔隙與裂隙介質界面間的交換項的非線性偶合，使演算法十分困難.本文討論了無生化過程時的幾種求解方法，數值結果表明：用三次迎風插值法對常見的對流項占優勢，且場變量有較大梯度的問題較適用.在討論有生化反應過程時，利用對流項與生化反應項的特徵時間量級估算，給出了求生化過程作用子步的時間步長估算辦法.用上述方法所得到的模擬結果與解析解、無化學反應和有化學反應的實測值對比，吻合很好
  4. In the past studies of arc - length method, the works mainly focused on the structural geometrical nonlinear analysis. in the case of the application to the material nonlinear analysis of concrete structure, especially when the concrete strain - softening behavior is included in the constitutive model, the studies are limited

    而將弧長法用於混凝土結構的材料非線性分析時，由於餛凝土開裂等因素引起的應變局部化，使得求解存在一定的困難，尤其是當混凝土本構模型中包含應變軟化段時，求解困難更為明顯。
