All closed-packed arrangements are built by stacking of close-packed layers of the type . 所有密堆積排列都是由密堆積層排列而成的。
The re - suits demonstrate that the carbon fibers which have serious skin - core structure , few graphite layers which intricately piled up have low mechanical properties 結(jié)果表明,造成碳纖維力學(xué)性能低的直接原因可以歸結(jié)為嚴(yán)重的皮芯結(jié)構(gòu)、芯部組織疏松或有孔洞出現(xiàn)、晶相少且無明顯取向、石墨層排列紊亂。
In a camera , light rays pass through a series of lenses that focus images onto film . in a healthy eye , light rays pass through the cornea and lens , which focuses images onto the retina , a layer of light - sensing cells lining the back of the eye 在照相機(jī)中,光線經(jīng)過一系列的透鏡,把圖像聚焦在膠片上,在健康的眼睛中,光線通過角膜和透鏡,把圖像聚焦到視網(wǎng)膜上,而視網(wǎng)膜是一層排列在眼底的光敏單元。
The study is imitating subulate tool penterite armor fabric by method of test for puncture of paperboard and corrugated fiberboard , and to ascertain the laver of armor fabric for absorb energy and arrestment , and any difference angle to compare the rank of defying ball , for understanding the sharp to the rank of annor fabric defy penterite energy , and penterite deep , the lose energy relation of sharp 摘要本研究是以沖孔強(qiáng)度試驗(yàn)機(jī)測試,模擬尖錐利器攻擊穿刺防彈衣,且對(duì)于防彈衣層數(shù)間的阻抗作用及能量吸收的情形,并對(duì)各種不同角度的抗彈織物疊層排列作相互比較,進(jìn)而?解尖錐對(duì)防彈衣的抗穿透層數(shù)之能量及穿透深度、錐度之能量耗損之間關(guān)系。
But owing to the constant presence of air currents , arranging both the dust and vapour in strata of varying extent and density , and of high or low clouds which both absorb and reflect the light in varying degrees , we see produced all those wondrous combinations of tints and those gorgeous ever - changing colours which are a constant source of admiration and delight to all who have the advantage of an uninterrupted view to the west and who are accustomed to watch for those not infrequent exhibitions of nature ' s kaleidoscopic colour painting 不過,由于不斷出現(xiàn)氣流,把法埃與水汽分層排列,廣度不均,密度各異,加上高低空常有云層,不同程度地吸收并反射陽光,我們這才看到各種奇異的色調(diào)斑剝陸離,諸多絢麗的色彩變化萬千;任何人只要有幸將西方的景致一覽無余,只要有心觀看大自然不時(shí)展現(xiàn)的那一幅幅瞬息萬變的彩畫,都會(huì)為之贊不絕口,喜不自勝。
