  1. Finite element method for viscoelastic fractional derivative model

    粘彈性分數階導數模型的有限元法
  2. In the first part of the paper, on the basis of the weather processes of huai he basin from june to august in 1998, the difference and reliability of the two reanalysis data game and ncep from the fields of basic element, derivative, precipitation, and surface flux were studied by diagnostical and statistical methods. the results showed that the game reanalysis data is more reliable than ncep / ncar reanalysis data at the bottom and mid - high levels of troposphere, and at the precipitation and surface flux fields the case is just the same. in addition, the paper revealed that the game reanalysis data can show the evolution of the southwest vortex but the ncep / ncar reanalysis data cannot do so

    在第一部分，本文以1998年6 - 8月我國江淮地區的天氣過程為背景對game和ncep兩組不同的再分析資料的基本要素場、導數場、降水量場和地面通量場用氣候診斷和統計的方法進行了對比分析，結果表明，在對流層低層和中高層game再分析資料的基本要素場及地面的降水場和通量場較ncep再分析資料更為準確； game再分析資料能很好地反映出西南渦東移並影響江淮大暴雨的重要天氣特徵，而ncep資料則反映不出這一現象。
  3. Then it may be generally applied in engineering. we note that it is the first time that the o ( h6 ) cionvergence of the derivative at nodes is achieved by this technique for bicubic finite element, which is proved in the third chapter

    注意到利用這種恢復技術對雙三次矩形元我們第一次在節點處獲得了導數的o （ h ~ 6 ）強超收斂率，本文第三章給予了理論證明。
  4. Based on the duncan - chang e - b model, which can simulate earth - rock dam ' s non - linear mechanics behavior well, the paper introduced the nature coordinate system to the stress space. in this way, hydrostatic stress and stress deviator were decomposed each other. therefore, a partial derivative formulation about displacement and parameter in finite element evaluation was derived in a closed form

    論文以能較好模擬土石壩非線性力學行為的duncan - change - b模型為基礎，通過引入應力空間下的自然坐標系，分解應力球量與應力偏量，從而導出一個在有限元計算中，位移對參數偏導數的閉合形式公式。
  5. Application of jaumann derivative in finite element analys

    焦曼導數在有限元分析中的應用
  6. When cable interacted under the load both of gravity and inertia force, derivative equation of cable ' s defection curve in space is deduced to study cable ' s rigidity movement, and flexible deformation is also determined by finite element method

    分析了懸索上各離散點的位置、速度、加速度和慣性力。推導了在重力和慣性力共同作用下懸索的空間撓曲線微分方程，並研究了懸索的剛體位移和彈性變形。
  7. A letter or symbol in typography written above a set name to denote a power or a derivative, or to identify a particular element of that set

    在印刷技術中，寫在一個集合名上方的一種字母或符號，用來表示乘方或導數，或用來標記該集合中的某個具體元素。
  8. The results show that the pyrrole - derivative was successfully electropolymerized on the surface of the electrode. the data estimated by edx results revealed the density of the pyrrole - derivative on the electrode was about several nmol per square milimeter. the 3 - pyrrole - dna also was successfully deposited on the electrode surface by electropolymerization because the edx characterization of polymer shows that the phosphor element was appeared

    結果表明， 3 -吡咯甲基-四聚乙二醇單醚可成功地聚合到電極表面，進一步的計算表明，電極表面修飾的3 -吡咯甲基-四聚乙二醇單醚鏈的密度為每平方毫米幾個nmol的數量級，且因聚合方法的不同密度有所差異。
