For the rod penetrators used for 30mm naval gun, the structures, the ballistic performance, the penetration and their design are studied systematically. in the paper, the reasonable design of sabot and projectile core is presented and the influence of various factors on ballistic performance of rod penetrators is analyzed. additionally, the optimum design techniques in exterior ballistics for the small caliber fin - stabilized and sabot discarded penetrators are developed
本文對海30艦炮適用的桿式脫殼穿甲彈的結構特性、彈道特性、穿甲威力及設計方法進行了系統研究,提出了合理的彈芯結構和彈托方案,研究了各種因素對桿式穿甲彈外彈道性能的影響,建立了一套小口徑尾翼穩定脫殼穿甲彈外彈道優化設計方法,並利用該方法在一定的戰術技術要求下對海30艦炮尾翼穩定脫殼穿甲彈進行了優化設計,得到了優化方案,研究結果對海30艦炮以及同類小口徑火炮桿式穿甲彈的設計有重要的指導意義。Abstract : researches on unformaldehyde unironing finishing are summarized in this paper. functions and deficiencies of glyoralamido, water soluble heat reactive polyure thane, bishydroxyethyl - sulfoue, natural high precision chitosan, reactive organosilicon, amyloidosis epoxide, multiple carboxyl acid compound are also analyzed and compared
文摘:綜述了無甲醛免燙整理方面的研究,分析比較了乙二醛-酰胺類整理劑、水溶熱反應性聚氨酯、雙羥乙基碸、天然高聚物殼聚糖、反應性的有機硅、澱粉改性物、環氧類整理劑、多羧酸化合物等無甲醛抗皺整理劑的功能以及各種整理劑存在的不足Through experiment and analyzing the changes of the thickness, rigidity, tensile strength and the opening rate of the conduits caused by the different kinds of coating material, the thickness of the coating and the different braiding structures, we investigate the physical and mechanical, properties of the braided conduits. the results show : the chitosan is easy to form the film structure on the surface of the conduits increasing the conduits ' rigidity clearly ; the rigidity and opening rate of the braided structure with inserted reinforcing yarn are better than the others, this will prevent the conduits collapsing and distorting effectively in the practical uses, so we select conduits of this structure for animal experiment
在導管的物理機械性能研究方面,本課題通過塗層劑的種類( pgla丙酮溶液和甲殼胺漿液) 、塗層劑的厚度、導管的編織結構三個方面分析它們對導管的厚度、硬挺度、拉伸強力和孔隙率等性能的影響。測試結果顯示:甲殼胺塗層易於在導管表面成膜,對導管的硬挺度有明顯提高,塗層效果較好;加筋結構神經導管在硬挺度和孔隙率方面優于其它導管,能有效防止導管在實際應用中的塌陷變形。Divers have discovered a new crustacean in the south pacific that resembles a lobster and is covered with what looks like silky, blonde fur, french researchers said tuesday
