此網帶由雙股右螺旋或由雙股左螺旋盤條與一根串條連接而成，網帶拼接方便，網眼一般小於單股加強編織的網眼，編織牢固，不易變形，維修方便。能用於高溫的自動流水線，輸送重物，機械工業上零件的熱處理，各種較大物品的烘乾。The results indicated that, the fabrication process of ultra - fine grain material is mainly determined by the stress, rotate speed and the flux of cooling water. the grain refining and the hardening effect are mostly affected by the rotate speed and the flux of cooling water. compared with commercial ly12, the invalidate strength and the prolongation rate of the ultra - fine grain material are properly improved in the measurement of compression property ; and the abrupt change of the dilatability of the ultra - fine grain material at 500c is found ; also the phenomena of which the grain size of these microstructures is stable when annealed under 300c is observed
研究表明，採用本文提出的摩擦壓扭強變形區轉移法可以得到棒狀的超細晶材料，軸向壓力、扭轉速度和溫度是採用該方法制備超細晶材料的主控參數；試件的旋轉轉速和冷卻速度對變形區晶粒細化和硬化效果影響顯著；超細晶ly12的壓縮性能與淬火+自然時效狀態的ly12壓縮性能相比，斷裂強度和延伸率均有一定程度的增強；超細晶ly12的熱膨脹系數在550左右發生明顯的變化。For bilateral symmetry objects, the techniques on symmetry - point detection and symmetry - axis extraction are presented based on harmonic conjugation relationship. for rotated symmetry objects, the techniques on rotated units description and rotated symmetry center extraction are presented based on center invariants of objects. further more, by using 3d invariants and 2d projective transformation, an approach to recover shape from part symmetry objects is realized on some conditions
（ 3 ）深入分析了2d對稱性目標透視成像的幾何特點，將共點四線交比用於目標輪廓上的關鍵點的特性描述中；利用調和共軛關系，提出了一種針對左右對稱型目標的對稱點檢測和對稱軸提取的演算法；利用交比關系構造了目標的形心不變量，提出了一種針對旋轉對稱型目標的旋轉對稱單元判定、旋轉中心提取的演算法；進一步利用3d不變量和2d射影變換，實現了一定條件下的對稱性目標的形狀恢復技術。
