  1. In this work, we detailedly introduced the whole ideas of rkdg finite element method and the theory of constructing gas - kinetic schemes based on boltzmann equation. and then presented a kind of new computational method for solving id and 2d compressible euler equations, i. e. firstly, we discretize euler equations in the space with discontinuous galerkin finite element method ; secondly, we discretize temporal variable t with runge - kutta formula ; thirdly, for numerical fluxes constructing, we give two kinds of different numerical fluxes - kfvs and bgk numerical fluxes by using gas - kinetic schemes

    本文分別對rkdg有限元方法的整個思想和基於boltzmann方程的分子動力學格式的構造思想給予了詳細的介紹，並分別結合rkdg有限元方法與kfvs數值通量和bgk數值通量的構造方法，給出了一種求解一維、二維可壓縮流體力學方程組新的計算方法，即，我們先用間斷有限元方法進行空間離散，然後再對所得到的半離散格式使用runge - kuttatvd方法進行時間離散，得到全離散格式。
  2. Firstly, the theory of compound foundation and pile foundation are summarized in this paper. the finite element, displacement models and computational program are introduced, then how such factors as the stiffness of pile, the ratio of length and radius of the pile & replacement ratio influence the settlement of compound foundation are analyzed. there has the best modulus of pile, the best of the length & replacement ratio and some data have been obtained

    首先總結了復合地基和樁基的理論和設計計算方法，對有限單元和位移模式以及有限元計算程序進行了介紹，然後分析了樁的剛度、長徑比、置換率等因素對復合地基沉降的影響，證實了帶承臺復合地基存在最佳樁土模量比、最佳長徑比和最佳置換率，並得出了相應的數值可供工程實踐參考。
  3. The finite element analysis method based on contact problem is a numerical algorithm used for solving contact problem of connection interface, which is developed from the general fem. this method is a combination of elasticity theory and fem, also it is an important aspect of computational structure mechanics

    考慮接觸問題的有限元分析法是在傳統的有限元法基礎上發展起來的處理連接面接觸問題的一種數值計算方法，它是彈性力學基礎理論與有限元方法相結合的產物，是計算結構力學的一個重要分支。
