  5. As the time trend function represent the impact of economic development on consumption, in the paper the semi - parametric model with deterministic time trend function is firstly used to make empirical study for cointegration test between actual consume and income per capita of chinese urban residents from 1978 to 2005, and the results show that there do exists cointegration between consume and income with income having important effects on consume, while the time trend form is not as what we usually suppose

    摘要由於確定性時間趨勢項代表了經濟發展等的因素對消費的影響，故本文首次基於帶有非參數時間趨勢項的半參數模型對我國1978 ~ 2005年的消費收入進行了協整檢驗，實證結果表明：轉軌時期我國城鎮居民人均收入與消費之間存在著長期均衡關系，收入是消費的一個重要決定因素；同時趨勢項的影響也並不是如很多文章描述的那樣具有直線形式。
  6. 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。
  7. In addition, we often encounter a general problem - it is very difficult to describe a complex shape with a single bezier curve precise. method of bezier definites shape of curve, which is global project. if you locally modify curve, it is necessary to affact the global. it is that method of bezier has character of global control, but it has not charater of local control. by way of arbitrary partition. arbitrary degree elevation, that may increases control point. increases potential active character of controling curve. therefore, the thesis discusses mainly the problem of local free - form deformation, which may make bezier curve deform continuely and gain wanted figures. however, no matter what free - form deformation based on extension factor for parametric curve or arbitrary partition will reduce smoothness of parametric curve

    另外，我們經常會遇到一個普遍問題，就是難以用單一的貝齊爾曲線段描述復雜的形狀。貝齊爾方法對形狀的定義是整體方案，欲對其作局部修改，必然會影響到整體，即貝齊爾方法是有整體控制性質，但卻缺乏局部控制性質。通過任意分割和任意升階得出所要變形的一段，以及增加控制點，增加對曲線進行控制的潛在靈活性。
  8. The second case is 1 / 2 subharmonic resonance - principal parametric resonance and 1 : 1 internal resonance. the final case is primary resonance for the second mode - principal parametric resonance and 1 : 2 internal resonance. the adjoint operator method and the theory of normal form are used to investigated the normal forms in the four dimensional nonlinear systems with cubic nonlinearities
