  1. Calculation of the band structures in two - dimensional phononic crystals consisting of elliptic cylinders

    二維橢柱散射體聲子結構的計算
  2. A patch antenna with etched holes on the ground plane is also studied. the performance of the antenna at the resonant frequency is analyzed by using the fdtd method together with the pml boundary treatment. the results show that the surface waves are suppressed greatly, the bandwidth is improved and a 1 odb reduction on the sidelobe level is achieved at the 110 and 260 directions in the e plane

    全面地研究了地面腐蝕周期孔結構的電磁體貼片天線在基波頻率處的性能,用fdtd方法並結合pml邊界處理技術對該天線所取得的研究結果顯示,本文設計的地面腐蝕型電磁體結構抑制了貼片天線中的表面波,增加了天線的寬,並有效地削弱了旁瓣,使天線的e面方向圖上110和260方向的兩個旁瓣被削弱了10db 。
  3. A patch antenna with air holes in the substrate has been designed. the finite - difference time - domain ( fdtd ) method together with the perfectly matched layer ( pml ) boundary treatment has been used to study the performance of the antenna. it is shown that the surface waves are significiently suppressed, the frequency bandwidth is improved, the sidelobe levels are reduced and consequently the gain in the forward direction is improved by 14 db ( about 4 db higher than the value reported previously )

    設計了一種基底鉆周期孔結構的電磁(光子)體貼片天線,用fdtd方法並結合pml吸收邊界條件對該天線進行了研究,結果表明本文所設計的基底鉆孔型電磁體貼片天線取得了多方面的性能改善,與普通天線相比,基底中的表面波受到很大抑制,天線的寬增加,遠場方向圖上天線的旁瓣和背瓣被明顯削弱,向前輻射的增益由原來的12db增加到26db ,增加了14db ,比文獻上報道的gonzalo等人的研究結果提高了4db 。
  4. These special optical properties make clc possess of great potential application such as testing and analyzing, using as broadband reflective polarizer or circular polarization filters and field - display and so on. the most of applications are relevant to the choice reflection property. this property depends on molecules arrangement of its planar structure

    膽甾相液的這些獨特的光學特性就決定了它有著很大的潛在應用價值如:測試分析、寬反射式偏振片、偏振濾光片及場致顯示等,這些應用均與膽甾相液的平面排列態的選擇反射特性有著很大的關系,而其選擇反射特性主要取決于液分子的排列狀態。
  5. A walkway takes visitors slowly downwards around an enormous round column - shaped water tank. gor geous tropical fish dart about at the top level, and you can see all kinds of bearded corals swaying back and forth in the water, before you finally come to the world of a sunken boat. the sight of it lying on the seabed, its skeleton spotted and streaked as it rusts away, sends shivers down one s spine

    珊瑚館耗資數億元,遊客沿著巨大柱形水槽緩步下行,絢爛的熱魚就在頭頂往來穿梭,還有須發飄飄的各式珊瑚款擺搖曳,最後來到海底的沈船世界,銹蝕斑斑寒意逼人的船骸,配上瑩透亮的魚群,可以激發孩子們的無窮想像。
