  3. The related physical equations ( yang - laplace equation and hagen - poiseuille equation ) were re - derived for different pore shapes. and the effect of using different pore model such as circle, elliptical and slit pore model to determine pore size and its distribution was investigated

    計算結果表明當假設孔為橢圓形時，液體置換法表徵得到的結果與掃描電鏡、比重法分析得到的實驗結果比較吻合，也可以較好地反映孔的實際形態結構。
  4. According to the experiment of influences of fiber structures and the width of edge channel on flow filling, it was found that even a small gap ( l or 2mm ) between the preform and the mold edge could also disrupt the flow pattern, which evidently changed the local permeability of preform. the filling process was simulated using the permeability for different edge width predicted by a. hammami or poiseuille model, which shown good agreement with the experiment results

    實驗研究了纖維鋪層結構及流道縫隙的寬度對充模流動的影響，發現在纖維預成型體和模具壁間存在的較小的縫隙也會對邊緣的流動產生干擾，進而影響增強材料主體的滲透；對于不同的縫隙寬度，分別根據a . hammami模型和poiseuille模型預測邊緣等效滲透率，並進行充模過程數值模擬，與實驗結果吻合較好。
  5. ( 2 ) with f varying, there exists a number fr which is about - 1 ( curvature, torsion and dean number have little influence on fr ), when f > fr, the maximum of the axial velocity is near the outside bent and the friction factor ratio increases with f increasing ; when f < fr, the maximum is near the inner side bent and the ratio increases with f decreasing ; when f = fr, the distributions of the axial velocity are similar to those of poiseuille flow and the friction ratio is about 1

  9. In present dissertation, firstly an analytical study on the force and deformation of an er single chain under poiseuille flow is presented from the point of microscopic view. an approximate solution of the poiseuille flow in a tube with rectangular cross is derived from galerkin approach. the balance equation of moment for the er chain is established to avoid using point - dipole model, which is not accurate enough in the case that dielectric particles are adjacent to each other

    本文首先從微觀的角度，分析電流變鏈在poiseuille流動中的受力以及變形，分析過程中推導了矩形截面管內poiseuille流動速度分佈的galerkin近似解，並採用理論力學軟索模型對電流變變鏈的受力進行分析，從而避免了點偶極子近似在粒子相距較近情況下引起的誤差。
  10. This is to say, pu composite hollow fiber membranes pore size can become large with transmembrane pressure increasing, and can recover completely with transmembrane pressure reverting to original pressure at a specification condition. from the hagen - poiseuille equal ion, pu composite hollow fiber membrane pore radius magnification was calculated. in our experiment, the variation of membrane pore radius attained to much six times larger than the primitive membrane pore radius
