A single are needle sewing blind stitching, a sewing thread hook taking up thread, forming type 103 single thread chain stitch
單弧針擺刺料、擺動線鉤勾線，形成103型單線鏈式線跡。採用圓筒式機構，適合襪子、手套、羊毛衫、褲管口等暗縫。Under the assumption that the inner surface of stator sleeve and outer surface of rotor are smooth, taking the fact into account that the temperature of stator sleeve of evaporation cooling motor keeps almost the same, horizontal evaporation cooling motor is simplified as a physical model of two coaxial sleeves, with outer sleeve ( the stator ) holds still and keep at constant temperature and inner sleeve ( the rotor ) is rotating and heated
本文通過數值和實驗手段研究了臥式蒸發冷卻電機楔形氣隙中的流體流動、傳熱現象。本文在定子套筒和轉子表面光滑的假設下，針對蒸發冷卻電機定子套筒壁面基本恆溫的特點，將實際蒸發冷卻電機簡化為同軸套筒內筒加熱旋轉、外簡靜止定溫的物理模型。In order to overcome the shortages resulted from hypothesis of small deformation in radial symmetry based on thick - wall cylinder, plane stress and uniform pressure about residual stress around cold - expanded hole, a new model was proposed which takes into consideration the effect of split - sleeve, the different states along thick direction of specimen
摘要針對目前在研究冷擠壓孔邊殘餘應力時，大都採用基於厚壁圓筒的軸對稱小變形、平面應力狀態、孔邊受力為均布載荷等假設所帶來的不足，提出了在三維真實模型狀態下，考慮襯套對孔邊受力的影響、試件在厚度方向上的應力差異等因素。
