  1. A new approach to parametric design is presented, which is child - graph based, and which design a 2d sketch in sequence. in this approach, the sketch is designed with simple elements such as points, segments, circles or child - graphs which is combination of above simple elements ; geometric elements is designed in sequence can implement the function of unwell defined ( less - constrain ) parametric design. 2dand 3d constrains is treated consistently

    設計並實現了該特徵表示模型的數據結構。該特徵表示模型是系統各種演算法的基礎。不同於常見的用底層圖元（點、線、弧）進行設計的二維全約束求解方法，提出並實現了一種基於子圖的序列化草圖設計方法。
  2. Using the formulized approach to the su ( 1, 1 ) h ( 4 ) time - dependent system, which is derived from the combination of the formulation of the time - dependent bogoliubov transformation and the evolution equation of the system, we obtain the time evolution operator, state function and heisenberg uncertainty relation of the parametric oscillator with cavity losses under the weak coupling approximation. we also discuss the squeezing property of the system

    本文利用含時波戈留波夫變換與時間演化方程相結合得到的求解su （ 1 ， 1 ） ? h （ 4 ）量子系統的時間演化算符和演化態的普遍公式，我們導出了帶腔損耗的參數振子在弱耦合近似下的演化算符，態函數和不確定乘積，並討論了系統的壓縮特性。
  3. An explicit formula of ultimate strength is achieved according as combination of elastic large deflection method and rigid plastic method for perfect plates. 2. the explicit formulae with damage parameters as variable of reduction factors for ultimate strength of damaged plates are achieved by curve fitting based on a mass of numerical computation for parametric imperfection and damage of plates

    將板格的各種缺陷和損傷形式參數化，通過大量數值計算擬合出受損板格極限強度折減系數的以損傷參數為變量的顯式表達示，用折減系數對完好板格極限強度進行折減得到受損板格極限強度公式。
  4. The thesis discusses two respects of contents : one is deformation of combination of parametric curve. the other is smoothing of combination of parametric curve. bezier curve has good character, because it uses a sequnce of special basic function

    本文論述了二個方面的內容：一是組合參數曲線的變形。二是組合參數曲線的磨光。對于貝齊爾曲線，由於它採用一組獨特的基函數，所以它具有良好的優良性質。
  5. In order to optimize the perpetuation tensioning tonnage of prestressed pier anchor wire of goupitan arch dam, first the scheme contrast method is adopted to define the perpetuation tensioning tonnage combination of the primary and secondary anchor wire, but the optimization result is that the pull - anchor coefficient is too big ; then the body form of the pier is optimized ; finally the anchor wire perpetuation tensioning tonnage is optimized by using ansys optimization design module based on parametric fem, the optimization result is acceptable and the pull - anchor coefficient is lowered down

    摘要為優化構皮灘拱壩中孔預應力閘墩錨索永存張拉噸位，首先採用方案優選的方法確定主次錨索永存張拉噸位組合，但優選結果拉錨系數偏大，再對閘墩體型進行優化，然後採用基於參數化有限元的ansys優化設計模塊對主次錨索永存張拉噸位進行優化，優化結果滿足應力控制要求，降低了拉錨系數。
  6. Based on the analysis of the shortcomings of traditional designs and fan comparability characteristics, the thesis fully studies technical paths of fan parametric design in combination with modern database software techniques, and exploits a complete interactive program system to operate the parametric design for series of centrifugal fans under the support of systematic software of visual basic ( vb ), access and catia. the major research work in the thesis is as follows : 1. ) analyzes and summarizes comparability theory and comparability design of fans ; 2. )
