    其次，本研究進行了「矩陣與幾何變換」這一選修專題的試驗班教學，對所做教學設計的科學性、所編寫教學材料的有效性與適應性進行了實踐檢驗，結果表明，在高中數學課程中開設矩陣與幾何變換這一選修專題不僅必要而且可行；矩陣與幾何變換這一選修專題的知識既符合學生全面發展的需要，又符合學生的學習特點；發現矩陣與幾何變換對學生全面發展所具有的促進作用主要有：能開闊學生視野，增強學習興趣，增加數學學習的信心，促進學生辯證思維能力的發展，有利於培養學生自覺應用數學的意識與能力等。
  2. The analytical example is min - river cable - stayed bridge, which is the third longest cable - stayed bridge and the longest composite beam cable - stayed bridge in the world, with main span 605m. the paper set up a 3d model of the bridge with ansys finite element program, considering the geometrical and material non - linearity

    以青州閩江大橋這座主跨長605m的大跨度疊合梁斜拉橋為例，利用ansys大型通用程序建立成橋階段、懸臂階段的空間模型，在計算中考慮了材料非線性和幾何非線性的影響。
  3. On the basis of the basic theories and methods about stability analyses, arc - length method is used to analyze the geometrical nonlinear stability of the structure. and the effects of the rise - to - span ratio and the prestress in cables etc. on the structural stability are discussed

    本文在介紹了結構穩定分析理論和方法的基礎上，採用弧長法解算了環狀索桿結構的幾何非線性穩定性問題，並研究了矢跨比、預應力等結構參數對其穩定性的影響。
  4. Spatial geometrical nonlinear analysis of large - span bridge with high - pier

    高墩大跨橋梁空間幾何非線性分析
  5. The linear solution and nonlinear solution were compared, the structure ' s obvious geometrical nonlinear character was found. then the buckling analysis of the structure was made, and compared corresponding dome, the conclusion was made that ribbed truss and pre - stressed cables improved the structure ' s limit buckling load. at one time, the buckling analysis of structures with different rise - to - span were made, and discovered that buckling load and stability can be improved with high rise - to - span

    通過對該結構的線性解和非線性解的比較，發現結構具有明顯的幾何非線性特徵；對加肋預應力穹頂結構作了屈曲分析，並將它的結果與相應的單層網殼作了比較，得出了由於肋桁架和預應力索的存在，加肋預應力穹頂結構的極限載荷大幅度提高，比一般的單層網殼結構具有更好的穩定性能的結論。
  6. Stability coefficient of large span cfst arch bridge is less than that of considering the geometrical nonlinearity, its numerical value decreases approximate 12 % ; stability coefficient of large span cfst arch bridge taking into account geometrical nonlinearity and material nonlinearity is smallest, and the numerical value is about 45 % of elastic stability coefficient

    拱肋的最大橫向位移為1 . 126米，說明對在該橋型運營實行監控檢測時，可以把雙重非線性分析所得的最大位移作為參考依據。幾何非線性對大跨度鋼管混凝土拱橋的穩定性影響較小。考慮幾何非線性后，穩定系數僅下降了12 。
