    首先，在前人研究成果的基礎上，對錨桿與圍巖的相互作用機理進行研究，利用全長錨固錨桿的中性點理論，從等效均化的角度來考慮錨桿對圍巖的加固作用，並推導了在簡單荷載作用下，含有襯砌、等效加固后的圍巖、原始圍巖三者的彈塑性解析解，對工程設計有著重要的參考意義；在數值模擬方面，以考慮錨固圍巖滿足規則化庫侖摩擦模型為基礎，利用虛功原理推導了接觸問題的有限元方程的計算格式，為開發運用大型商用有限元軟體msc . marc提供了理論根據，也形成了本文的理論基礎：最後，論文以南水北調東線穿黃隧洞穩定性分析項目為工程實例，利用本文所述的接觸問題的摩擦模型理論，對錨桿支護結構的應力場、位移場的變化規律進行了研究，分析了加錨支護對隧洞圍巖應力、變形的影響。
  2. The research result indicated : for the strip primary mirror discussed in this article, the hexagon light - weighted cell has the best structural rigidity quality, the square cell is a little worse, the triangle cell is the worst ; there is an optimum on primary mirror thickness ; on condition of 1g gravity load combining with 4 centigrade uniform temperature rising, the thinner and higher of the flexible support reed, the better of the primary mirror surface figure. the decision of the structural parameters of the flexible support reed must take static rigidity, dynamic rigidity, static strength and dynamic strength of primary mirror assembly into account

    研究結果表明：對于本文的長圓形主鏡，採用正六邊形輕量化孔，鏡體結構剛性品質最好，正方形次之，正三角形最差；主鏡鏡體厚度存在最佳值；主鏡組件在1g重力、均勻溫升4共同作用的工況下，主鏡柔性支撐簧片厚度越小、高度越高，主鏡綜合面形誤差（ p - v值）越小，但同時主鏡組件的剛體位移增大、固有頻率下降，因此柔性支承結構參數的確定要綜合考慮主鏡的綜合面形誤差和主鏡組件靜態剛度、動態剛度、靜態強度和動態強度等因素。
  3. Compared with a delta wing aircraft, the double - delta wing configuration has better aerodynamic performance at high angles of attack. an operational analysis was introduced as a method for evaluating training effectiveness of trainer aircraft. approaches to the engineering estimation of aerodynamic characteristics for aircraft with a double - delta wing configuration were studied, and the procedures for determining aircraft performance indices formulated. taking training effectiveness as the objective function and geometric parameters of the wing platform as design variables, through a numerical multivariate optimization arithmetic, the conceptual design optimization for a certain fighter trainer aircraft with double - delta wing configuration was carried out under the constraints of tactical and technical requirements and interrelated geometry. agreement of a calculation example with engineering practice indicates that the optimal design has higher training effectiveness than the baseline design, and in addition, improves the structural force - bearing conditions

    雙三角翼氣動布局比三角翼飛機具有更好的大攻角空氣動力特性.引入了評估教練機訓練效能的作戰分析法，研究了雙三角機翼布局飛機空氣動力特性的工程計算途徑以及飛機性能指標的確定方法.以訓練效能作為目標函數並選取機翼平面形狀的幾何參數為設計變量，採用多變量數值尋優方法，在戰術技術指標及相關幾何約束條件下，對某高級教練機的雙三角機翼氣動布局方案進行了優化選擇.算例表明最優方案不僅比原準方案具有更高的訓練效能，還改善了結構的受力情況，與工程實踐吻合
  4. First, introduce the reasons and character of current banking m & a, then summarized the former studies of the three ways of m & a to efficiency gaining : size versus size economy, m & a versus banks efficiency, and m & a versus shareholders wealth. then introduce the research approaches of m & a efficiency gaining, especially the approaches of m & a versus banks efficiency, such as parametric frontier approaches and non - parametric frontier approaches. in the following, through roe model and dea model to study the relations between size and efficiency, finding : middle size banks efficiency is higher, larger banks have n ' t scale economy, small banks have low em, and through directly analyzing m & a efficiency of four commercial banking m & a case in china, finding : the past - merged efficiency of shanghai pudong development bank has been improved, and others have been deduced, but after three years the efficiency increased little by little

    首先，分析了當前銀行並購的主要原因、特徵以及我國銀行並購的現狀與特點；接著對銀行效率水平的概念進行分析，綜述了國外對銀行並購與效率獲利的三方面的研究（考察銀行的規模與效率這種間接方式、比較並購行並購前後的效率以及並購行與非並購行的效率和考察上市銀行並購前後股東財富的變化這兩種直接方式）的有關文獻；再次對銀行並購與銀行效率獲利的分析方法進行了介紹，其中詳細地研究了前沿分析法：參數分析法和非參數分析法，並指出了這些方法的特點；然後運用財務比率分析法和dea方法對我國商業銀行規模與效率從間接角度對銀行並購產生的效率獲利進行了實證研究，結果發現：中等規模的商業銀行的效率最佳，而小規模的銀行的em值較低，同時大規模的商業銀行的規模無效；同時利用我國已發生的四個銀行並購案從直接的角度對我國商業銀行並購的效率獲利進行分析，結果發現：除上海埔東發展銀行在並購後效率提高，其他三家銀行並購后的效率都有所下降，但並購后第三年效率又逐漸回升。
