  2. To solve the inaccuracy problem caused by the two existing methods ( average end - area method and prismoidal method ) used for the calculation of roadway earthwork volume, this paper puts forward a new concept of the 3 - dimensional algorithm that takes all the roadway geometric design procedures as a kind of geometrical operation between the ground model ( original terrain model ) and the roadway model ( designed model ) under certain constraints, and then presents a complete 3 - dimensional algorithm of roadway earthwork volume as well as its executable computer program. the algorithm benefits from the re - triangulation technique of constrained delaunay triangulation ( cdt ), which can yield a true volume value theoretically. through a number of practical tests covering varied intervals between adjacent cross sections, it is proven to possess a higher accuracy compared with that of traditional methods. all the work involved in this paper indicates that the 3 - dimensional calculation of roadway earthwork volume is feasible, more accurate and should have further application in practice

    針對目前廣泛使用的道路土方量計算方法平均斷面法和稜柱體法計算不準確的缺點，提出了三維土方量計算演算法的概念.該演算法以帶約束的狄羅尼三角化（ cdt ）為技術核心，認為所有道路幾何設計過程都是地面模型和道路（設計）模型進行幾何運算的結果.基於此，本文設計出相應的演算法步驟，同時完成了相應的軟體開發，使得該三維演算法能和傳統的方法進行對比.此外，結合工程實例，採用了不同的道路橫斷面間距對三維計算方法和傳統方法的誤差進行比較、分析.結果證明三維演算法具有更好的精度，該演算法可用於道路、場地平整等工程土方量計算
  3. Performance for a piezoresistive transducer pressure sensor to thermal and pressure environments can be predicted by finite element method. a simplified 1 / 8 model, considering silicon dioxide and nitride process as well as stack anodic bonding and adhesive bonding processes, was developed. the fem results were found to be comparable to experimental data. case studies suggested that pyrex stack induces certain amount of non - linearity, while it isolates hard epoxy nonlinear effect. flexible epoxy bonding or soft adhesive bonding is preferred to the packaging process. the viscoelasticity and viscoplasticity of bonding material will result in hysteresis and drift errors to sensor output. however, soft adhesive s influence on sensor can be ignored under relative stable environments. more over, detailed design and process information will help to improve modeling application

    熱、壓環境下壓阻變換壓力傳感器的性能可以通過有限元方法預測.這里研究了簡化的1 / 8模型，模型考慮了二氧化硅和氮化硅生成過程及堆陽極鍵合和膠粘結合過程.結果發現有限元預測結果和實驗數據具有可比性.範例研究表明，硼硅堆導致產生一定的非線性，但它隔離了硬環氧樹脂的非線性.在包裝過程中最好使用柔性環氧黏合或軟黏膠性結合.黏合材料的黏彈性和黏塑性將會導致傳感器輸出的滯后和漂移誤差.然而，在相對穩定的環境下，軟黏合劑對傳感器的影響可以忽略.此外，詳細的設計和過程信息有助於提高模型的適用性
  4. A scale coefficient method based on the fem has been proposed to predict the optimum blank in sheet metal forming in this thesis. in order to improve the precision of results and reduce iterate time, at adjusting the original curve, this method is n ' t giving the same adjustment, but giving the corresponding adjustment based on calculation of scale coefficient and shape error of each node to the curve

    本文在有限元模擬的基礎上提出了一種新的板料優化的方法? ?比例因子法，該方法在調整初始輪廓線時，不是給各個節點一個相同的調整量，而是依各個節點的比例因子及形狀誤差值計算出相應的調整量，這樣調整的針對性強，計算結果更精確，需要迭代的時間也更少。
  5. For the existing test based on measurement residual, the main problem is that the data reconciliation procedure tends to spread the gross errors overall the measurements, which results in the detection failure

    通過構造一個基於測量值比例關系的f統計量，並與約束殘差統計量相結合，對穩態過程中出現的顯著誤差進行檢測。
