理论推导与计算表明：膜的导热性对真空膜蒸馏过程的影响可以忽略，膜蒸馏过程膜内质量传输机制是努森流与粘性流共同作用的混合流机制。 - ( 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
( 2 )当f变化时，存在确定的数值fr ( fr在- 1左右。曲率、挠率和dean数对fr的影响很小) ，当f fr时，轴向速度最大值偏向外侧，摩擦系数比随f增大而增大；当f fr时，轴向速度最大值偏向内侧，摩擦系数比随f减小而增大；当f = fr时，轴向速度的分布和poiseuille流近似相同，摩擦系数比约为1 。 - 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
本文首先从微观的角度，分析电流变链在poiseuille流动中的受力以及变形，分析过程中推导了矩形截面管内poiseuille流动速度分布的galerkin近似解，并采用理论力学软索模型对电流变变链的受力进行分析，从而避免了点偶极子近似在粒子相距较近情况下引起的误差。
