  1. After spinning fibre number of the fibres is normal ; as long as the components of island are dissolved away by solvent after processing, we can make up bundle superfine fibres

    紡絲后是以常規纖度存在，只有在後加工用溶劑將海成分溶解掉，才可真正得到束狀超細纖維束。
  2. Characteristic class of a fibre bundle

    纖維叢的示性類
  3. Abstract : with adopting of a frame of the principal fibre bundle. the article constructs a unified model of gravity and electromagnetic with torsion both in internal sp ace and in four - demensional space - time. the curvature on the bunde is calcula ted using connection theory in the principle fibre bundle. the action is construc tod with the curvature. the field equations are achieved. finally a discussion is made

    文摘:應用纖維叢理論，在內部空間和四維時空引入撓率，建立了引力與電磁場的統一模型.利用纖維叢聯絡論求出主叢的標曲率，由它構造作用量，求得場方程，最後作一些討論
  4. On physical layer, it consists of a variety of ne ( network elements ) with different functions connected by optical fibre cables. compared with pdh, sdh is more widely used in fibre optical communication system these days. the reasons of the wide applicability of sdh are : first, it provides worldwide standards for electrical interface and optical interface, which can promote multi - vendor interoperability ; second, it has the feature of synchronous multiplexing and flexible mapping mechanism, so it can use stm - 1 signal to bundle atm cells, fddi signals as well as pdh signals

    Sdh之所以具有強大的生命力和廣泛的適應性，主要有兩個原因:提供統一標準的光介面和電介面，使不同廠家設備實現橫向兼容;採用同步復用方式和靈活的映射結構，以基本傳輸模塊stm - 1為橋梁，與原有的pdh信號實現縱向的前向兼容，與atm 、 fddi等數字體制實現後向兼容。
