  1. Firstly, this paper summarizes modern weaponry stealth technology at home and abroad, and lays special emphasis on analyzing stealth problem of cruise missile ’ s guidance head cover, aerocraft radar canopy and other privileged sites. secondly it makes a research on related theories of transparent metallic mesh that applied to missile ’ s guidance head cover and aerocraft radar canopy, and deduces relational expression between transparent metallic mesh structural parameters and radar wave - shielding efficiency, infrared transmitting. we use laser direct writing technique to fabricate a metallic mesh ( dimension : 70mm 70mm ; line width : 5 m ; period : 350 m ) on glass surface, then do experiment to test radar wave - shielding of metallic mesh via radar transmitting and receiving device

    本文首先綜述了國內現代武器系統隱身技術方法;重點對巡航導彈導引頭和飛機雷達艙等特殊部位的隱身問題進行了研究,研究了金屬網柵用於導彈頭和飛機雷達艙隱身的相關理論,推導了金屬網柵結構參數對雷達波屏蔽效率和透紅關系式;用激光直寫工藝,在玻璃表上製作了一塊為70mm 70mm ,線寬為5 m ,線周期為350 m的金屬網柵;在實驗室里用雷達發射和接收裝置測試了網柵對雷達波的屏蔽實驗;認為利用金屬網柵技術對雷達波具有一定的屏蔽作用,而且不影響精確制導的紅線高效透過。
  2. Experimental constants include : ambient temperature 291k ~ 301k, rh 15 % ~ 21. 2 %, wind velocity 3. 2m / s at the nozzle position and horizontal to the spray fan, others are same as the fore experiment. the tendency of the two experiments results is consistent with the tendency from simulation. that indicate the improved shield spray is better than the original shield spray in reducing spray drift, and also more better than conventional spray without shield

    風洞試驗參數:噴霧藥液為含1 bsf的水溶液,風速1 . 4m s ,風向垂直於噴霧扇,溫度281k 288k ,相對濕度rh9 20 ;室內試驗參數:噴霧藥液為含2 bsf的水溶液,噴頭處風速為3 . 2m s ,風向平行於噴霧扇,溫度291k 301k ,相對濕度rh15 21 . 2 ;分別在噴頭下風向噴幅的空中和地布點收集飄失和飄移沉的霧滴量,作為評價減少霧滴飄失效果的指標:試驗結果表明:改進后的蓋噴霧減少霧滴飄失的效果好於雙圓弧未開口蓋噴霧,常規無蓋噴霧的霧滴飄失量大於開口蓋噴霧。
  3. Background : in vivo case reports and recent in vitro studies have indicated that aerosol therapy using facemasks can result in drug deposition on the face and in the eyes and that facemask design may affect drug delivery
