Abstract : the formation technologies, the structure and properties of tcs microporous man - made yarn - kind new polyester fibre which was spinned in tcs with some micrometallic - oxide have been studied. the results indicate that the rheological behaviour and spinnability of commixed polyester melt, and the structure and properties of the fibre, are relative to the spinning temperature, melt pressure, microporpus size for spinning, formation conditions, thermo - vascellum temperature, thermo - vascellum position and rolling speed, besides the viscosity of polyester cuts, coacervation particles, adding amount and size of micrometallic - oxide
研究表明， tcs微孔化共混聚酯熔體在成型加工中的流變行為和可紡性，及其纖維的結構性能除了與原料切片的特性粘度、凝聚粒子和共混聚酯中超細金屬氧化物微粒的添加量、粒徑等因素的影響有關外，還與紡絲溫度、紡絲熔體壓力、噴絲板微孔尺寸、冷卻成形條件、熱管溫度、熱管安裝位置以及卷繞速度等因素的影響密切有關。Cellulose acetates with different substitution degrees were synthesized with wood pulp as raw material and dodecylbenzenesulfonic acid as catalyst
摘要以木漿為纖維素原料、十二烷基苯磺酸為催化劑，制備了一系列不同取代度的纖維素醋酸酯。According to the special shape and operate requirements of the torpedo, the structure and moulding process of the torpedo shell are established, in which the body and overlay block with grooves are moulded by fiber winding, and close moulding respectively with the adhesive by limited stop compression. in the light of the selection of raw material system, composite system with outstanding performance are defined, based on which the mechanical properties are tested., with the overall consideration of structural characters and design demands, the main factors which may have effects on the strength and stability ( including stiffness section dimension, stiffeners space, skin thickness and skin lay angle ) is optimized one by one for the structure design parameters on the base of the fem model of skin, stiffness and layover block by fem. as a result, the prototype with 1 : 1 proportion and its structure and lay optimization design are completed. the moulding technology for polyurethane foam moulding the stiffened shell is obtai ned in terms of the design, manufacture moulding, experimental mould and tooling
依據在研產品特殊的外型結構和使用要求，確定了該型號水雷復合材料殼體的具體結構形式和復合成型工藝路線，即由纖維纏繞工藝成型主體異形件，閉模成型帶通槽外貼塊，用限位加壓工裝實現粘接的工藝路線；通過對原材料體系的篩選，確定了綜合性能較好的復合材料體系，以此為基礎進行了力學性能測試；運用有限元方法，建立了蒙皮、筋條和外貼塊的分析模型，綜合考慮結構特點和設計要求，對影響結構強度與穩定性的主要因素（包括筋截面尺寸、筋間距、蒙皮厚度、蒙皮鋪層角度）分別進行了結構設計參數的優選，最終完成了復合材料異形耐外壓殼體1 : 1樣件和縮比實驗件結構及鋪層優化設計；完成了聚氨酯泡沫胎成型內置加筋殼體的成型工藝技術研究；對縮比件進行外壓性能測試，並給出了應力、應變測試結果。" the concept is that systemic sclerosis, which is a severe disease characterized by systemic fibrosis, is at the beginning mainly a vascular disease, and we hypothesize that using major vascular drugs ( calcium channel blockers, endothelin antagonists, prostacyclins, phosphodiesterase inhibitors, etc. ) from the beginning and at appropriate dosage may interfere with the fibrotic process which seems secondary, " dr
「從概念上講，系統性硬化是一種以系統性的纖維化變性為特徵的嚴重疾病，早期主要表現在血管性的病變，因此我們推測早期、適量地應用主要作用於血管的藥物（如鈣離子阻斷劑，內皮素拮抗劑，前列環素，磷酸二酯酶抑制劑等）可能可以干預似乎是繼發發生的纖維化過程。 」" the concept is that systemic sclerosis, which is a seere disease characterized by systemic fibrosis, is at the beginning mainly a ascular disease, and we hypothesize that using major ascular drugs ( calcium channel blockers, endothelin antagonists, prostacyclins, phosphodiesterase inhibitors, etc. ) from the beginning and at appropriate dosage may interfere with the fibrotic process which seems secondary, " dr
