smokescreen 【軍事】煙幕;障眼法。

smokestack

This paper deals with theoretical study on extinction characters of non - spherical particles and their smokescreen , which is one of the fundamental researches of smokescreen technology . the mathematical radiation extinction model of particles is discussed , and numerical simulation of extinction characters of particle and smokescreen is developed 本文就非球形微粒及其形成煙幕的消光機理開展了研究,針對煙幕對輻射衰減的理論模型,進行了非球形微粒及其形成煙幕的消光特性數值模擬。

Thirdly , the cluster - cluster aggregation model is used to study the possible structure of aggregated smokescreen particle . we also develop the mathematical radiation extinction model of aggregated particle based on t - matrix method . associated with monte carlo method , another computer program is designed to simulate the extinction cross section and scattering cross section of actually aggregated particle 本文還將“凝聚體?凝聚體”凝聚模型應用于煙幕凝聚現象研究,模擬出了煙幕凝聚粒子的可能結構,并且根據t矩陣方法發展了凝聚粒子消光特性的計算方法,結合montecarlo方法,編寫了能夠模擬實際煙幕凝聚粒子消光截面、散射截面的計算程序。

At last , the radiation transmit process in smokescreen is discussed , and the transmitted radiation energy distribution is obtained from extinction characters of particles . the relationship between transmittance and smokescreen concentration is experimental studied , the experiment results agrees with calculated results . we also discuss the application limit and error of lambert - beer law in smokescreen studies 本文最后討論了輻射在隨機分布微粒形成煙幕中的傳輸過程,根據煙幕微粒的消光特性計算出輻射通過煙幕后的能量分布情況,討論了在煙幕研究中應用lambert ? beer定律的誤差問題,并對透過率隨煙幕濃度的變化情況進行了實驗研究,結果表明,理論計算結果能夠與實驗數據較好吻合。

In recent years , they paid more attention to the research , development and production of smokescreen equipment . the battles have proved that when attacking weapon ’ s efficiency reduced by 4 / 5 , while defending it could let the enemy ’ s weapon efficiency reduced by 9 / 10 戰爭證明進攻時煙霧能使敵方武器效能降低4 / 5 ,防御時能使敵方武器效能降低9 / 10 ,還有資料介紹,激光制導反坦克導彈在煙霧干擾下探測效能下降80 % ,命中精度下降60 % 。

The preparation and capacity of the smokescreen materials against infrared wave were studied in the dissertation . firstly , the new methods to measure the anti - infrared ability of graphite and carbon fibre with the dual - waveband infrared radiation instrument were be found 探討了影響粉體材料對紅外衰減能力的原因,進而分別在石墨和云母表面進行了化學鍍銅和化學鍍鎳,并測試和研究了化學鍍前后材料對紅外的衰減能力。

At present , one of the development trends of smokescreen is to improve its obscure power , so the measurement of smokecscreen obscure power is the most important content of the research on smokescreen 目前煙霧干擾技術的發展趨勢之一就是要提高煙霧的遮蔽能力,對煙霧遮蔽性能的測試就成為目前煙霧技術研究的重要內容。

As the effective way of obscuring important target , covering the army ’ s action and making the enemy ’ s fire power blind , smokescreen has catched every country ’ s attention 煙霧作為遮蔽重要目標、掩護部隊行動、迷盲敵人火力、干擾敵人偵察、觀瞄器材和精確制導武器的有效手段,已被世界各國所重視。

In modern warfare , smokescreen camouflage can puzzle and deceive enemy , improve the viability in battlefield , so it has won the favor of every country ’ s army 在現代化戰爭中,煙霧偽裝能迷惑和欺騙敵人,提高戰場生存能力,因而備受各國軍隊青睞。

Indeed , his allies suggest that attacks on mr trichet may create a useful smokescreen for the more important business of getting on quietly with economic reform 他的盟友建議他通過對特里謝先生的攻擊來為更重要的經濟改革事業制造煙幕。

“ when an italian says it ' s pasta i check under the sauce to make sure . they are innovators of the smokescreen . “意大利人說盤子里是通心粉,我一定會小心翼翼地再檢查一遍,看到底醬料底下究竟是什么。他們都是制造煙霧的高手。 ”

However , it could off course be a clever smokescreen engineered by the club to take the pressure of the playing staff 盡管如此,事情卻可能偏出預料之外,這個有可能只是俱樂部一手設計的一個高明的煙幕,去承受球員所受的壓力。

Smokescreen as an effective defense against precision - guided weapon becomes more and more important in high - tech warfare 煙幕作為一種能有效對抗精確制導武器的防御措施,在現代高科技戰爭中的地位日趨重要。

One year , $ 15 million and maybe an option for 2008 . this stuff with lilly is just a smokescreen 一年1500萬美元,或許加上2008年的選擇權。和莉莉有關的事情只是煙幕彈罷了。

Thirdly , the conductive mica powder was first to applied in the smokescreen field 首次提出將具有導電性的鍍鎳云母用于遮蔽紅外光的設想。

Rangers progress through a smokescreen created to cover their movement 別動隊員在煙幕環境的掩護下前進。

Unfortunately the smokescreen is not likely to help 不幸的是這道煙幕沒有任何幫助。

His wife, whom he had reduced to a state of complete subjection, was a most convenient smokescreen for him in business affairs . 給他壓得象奴隸般的太太卻是他生意上最方便的遮身牌。
