" now considered to be the founder of abstract art, his work was exhibited throughout europe from 1903 onwards, and often caused controversy among the public, the art critics, and his contemporaries
他的天賦異秉很快就擺脫了藝術學校所施加的制梏,他開始探索自己對繪畫的見解:我用調色刮刀將彩色的線條與團塊放置在帆布上,並竭盡我一切能力所及地讓它們唱出我所有的激烈感受…現在,他的作品被認為是抽象藝術的創始基礎,自一九三年以來更在全歐洲被展示,經常引起大眾、批評家,以及與他同輩之人的討論。The result of the research and more then 15 years of experience, has led to the development of a comprehensive software program, and unique materials, that give the company the ability to utilize thin films and technologies to manufacture high - quality, cost - effective, concealable, multi - frequency conformal antennas
經過研發及15年的發展經驗,公司可開發廣泛的軟體程序和獨一無二的材料,公司有能力利用薄膠片和技術製作高質量,合理成本,可隱藏,多頻的天線。A gas - jet - type vuv source that can give a spectrum in the wavelength range of 5 ~ 200nm was used in this paper to research of vuv radiation effects on upilex films which used as canopy of the space inflatable antennas and al / kapton films
利用射流式真空紫外地面模擬設備研究了5 200nm波長范圍內的真空紫外輻照對al / kapton薄膜與空間充氣展開天線透射面材料upilex薄膜的性能影響。The research of patch antennas based on photonic - bandgap ( pbg ) structures is a relatively new area. the goal is to improve the performance of the patch antennas by using the special features of pbg structures. though some good research results have been obtained by scientists in the world, there still exit some problems to be solved for improving the performaces and reducing the size, weight and cost
雖然國內外已經在基底鉆孔型、地面腐蝕型、高阻抗表面型、 uc - pbg型、覆層型和軟表面型電磁(光子)晶體貼片天線等方面開展了研究,但是在這些研究中還遺留著多方面的問題有待解決,以顯著改善天線的性能指標,減少天線的體積,重量,降低天線的加工費用等。Performance of inflatable antenna reflector hinges critically on the precision of the membrane surface. if the error is not in the range of limit, it will heavily decrease antenna gain and increase sidelobe level
形面精度是決定充氣展開天線反射器性能的一個關鍵因素,如果誤差不在允許范圍內,那麼它會嚴重降低天線的增益,增加旁瓣電平。It adopts both modern multimedia and computer, the latest technology in most advanced field of 21st centery. it has so much editing function. this changes people ' s concept of editing in turn of time and overcomes the fault of bad quality in video multi - tapes compounding and image copying
非線性編輯系統是在電視的數字化以及計算機技術在存儲容量、數據處理速度等方面發展到一定階段出現的,它集多項編輯功能於一體,改變人們按時序剪輯素材的傳統概念,克服了錄像帶多版合成、復制圖像質量劣化的缺點,提高了編輯效率,為編輯人員的藝術創作開辟了廣闊的天地。The paper ' s primary study work is aiming at dynamics and kinematics performance of large extensible satellite ' s antenna ' s expanding process at two expanding orderliness and three expanding mode. gains simulating calculated result
