  1. Glauca were suppressed all along, no release, but they still reached the canopy layer. this meant that this small parts of neolitsea aurata var. glauca could regenerate under the closed canopy, which was superior to the regeneration of

    7的冠層白毛新木姜子在成長過程中一直受壓，沒有出現釋壓，但這部分白毛新木姜子最終還是進入了林冠層。
  2. 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圓孔結構的電磁（光子）晶體貼片天線，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晶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，天線的帶寬增加，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 。
  3. Jacket is the most widely used offshore platform structural style. first of all, the paper summarizes the present achievements of dynamic analysis for offshore platform, and studies both the vibration isolation system for jacket and vibration - suppressed effectiveness. considering the style and character of jacket, and in order to make best use of dampers to reduce vibration, a damping isolation scheme, in which the damping layer is laid between the jacket cap and deck is put forward

    本文在總結國內外對海洋平臺結構動力分析研究現狀的基礎上，針對淺海導管架式海洋平臺的型式與結構特點，研究了導管架式海洋平臺結構阻尼隔振體系及其減振效果，為了充分發揮阻尼器的耗能減振作用，提出了在平臺結構導管架端帽和甲板之間設置柔性阻尼層的新型阻尼隔振方案。
  4. Then a simplified computational modal of damping isolation systems is established for a platform structure, and the relationships between the parameters of isolation layer and structural damping ratio, including their vibration - suppressed effect on the whole structure and the relative displacement of isolation layer are studied, and the simulation analysis under several representative load case of random wave force and earthquake affairs is performed. under random wave force, using complex mode theories, non - classically damp problems considering the interaction between the structure and wave, lying in deepwater, are studied. and the resolution solution of structural response are achieved. the results of calculating and analysing show that adding damping isolation to a jacket is an effective way to reduce vibration for offshore platforms

    針對某一典型平臺結構，建立了海洋平臺結構阻尼隔振體系簡化計算模型，進行了波浪荷載工況和地震工況的數值模擬，研究了隔振參數與結構阻尼比的關系以及它們對結構整體和隔振層層間相對位移的控制效果，運用復模態理論研究了位於較深水位的固定式導管架海洋平臺在隨機波浪力作用下考慮結構與波浪相互作用時運動方程中非經典阻尼的解耦問題，獲得了結構響應的解析解。
  5. Compared to non - tourist areas, in recreational areas, the number of plant species and coverage of vegetation in arbor layer and shrub layer decreased and the composition and community structure of vegetation trended to be simple. at the same time, regeneration of vegetation were suppressed
