武装直升飞机 meaning in Chinese
gunship
Examples
- Fire engines and ambulances raced to the scenes of the bombings as black smoke poured into the sky and u . s . attack helicopters circled overhead
消防车和救护车随后赶到出事地点，黑烟笼罩着天空，美军武装直升飞机在上空盘旋。 - Sicp / al matrix composites , with 5 , 15 and 25 % volume fraction of sic particles , were prepared by vacuum hot - pressing sintering processing in this paper . based on mechanics properties , sem observation and energy dispersive x - ray analysis , the interface reaction phenomenon of sicp / al composites made by vacuum hot - pressing sintering , as well as the reinforcement and fracture mechanisms of this composite were analyzed . the dynamic responses of sipc / al composites were studied by a split hopkinson high - speed pressure bar impact system which strain rate was from quasistatic state strain rate ( 3 . 3 10 - 3s - 1 ) to dynamic state strain rate ( 5 . 2 103 s - 1 )
本研究以武装直升飞机防护装甲材料为研究对象，采用真空热压粉末冶金烧结工艺制备了含sic颗粒体积分数分别为5 、 15和25的sic颗粒增强铝基复合材料，结合其力学性能、扫描电镜和界面微区能谱分析结果，分析了sic _ p al复合材料的真空烧结过程中的界面现象，以及材料增强和断裂机理，并利用hopkinson高速压杆冲击实验系统对其从静态到动态(应变率为3 . 3 10 ~ ( - 3 ) s ~ ( - 1 ) 5 . 2 10 ~ 3s ~ ( - 1 ) )的压缩破坏响应进行了研究，分析了不同体积分数sic _ p al复合材料高应变率压缩载荷下，材料的变形和微观损伤机理，以及利用高速冲击空气炮测定了改复合材料制备剃度复合板的穿透性能。 - The gunship is one of important weapons in modern war , and it acts an importance for the modern war . but it is threatened badly by the ground weapons . therefore , it is extremely important for the defend armor of gunship to increase its bullet penetrability resistance
武装直升飞机在现代战争中起着重要的作用，是现代常规战争中的重要武器之一，但其也受到地面武器的严重威胁，提高武装直升飞机防护装甲的抗弹穿透能力，对武装直升飞机本身的飞行安全也是至关重要的。
