文摘:提出半橢圓閉口孔型新概念和其內涵，分別從增大管坯變形量、控制管坯回彈、提高管坯邊緣剛性和運行的穩定性以及實現閉口孔型輥的共用性等四個方面論述了半橢圓閉口孔型輥的作用。For membrane contactor process, the binary gas mixture diffusion through the pore channel should be considered as a transition diffusion of the absorbed momentum a through the stagnant momentum b. and the process would consist three steps : transition diffusion through the pore channel, stephen diffusion in the pore edge, and the pore interaction in the membrane surface
對于孔形狀為近似橢圓形的聚丙烯微孔膜，在研究擴散問題時，其等效孔徑可採用葉孔擴散問題中的孔形狀校正公式來計算。在膜接觸器中，氣體通過微孔膜的擴散機理為過渡擴散，其擴散過程包括通過孔道主體的過渡擴散、微孔膜出口處孔道邊緣的stephen擴散以及孔之間的相互作用。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。The outline of fiber ' s tip has very great influence on the coupling efficiency. it is reported, using the way of grinding and melting to form a microlens on the fiber ' s tip, can increase fiber ' s numerical aperture, reduce the ellipticity of laser, and improve coupling efficiency
光纖端面的形狀對耦合效率有很大的影響，有文獻報道，採用拋磨燒熔等加工方法，可在光纖端面形成一個微透鏡，增大光纖的數值孔徑，對入射激光進行橢圓度校正，從而提高耦合效率。Numerical results of dscf are provided when the cavity is ellipse, square and diamond
