These four ship ' s class societies all use two holds length finite element modal near the central section. they mesh the finite element modal mainly according to the distance of longitudinal frames, we call this fine mesh finite element modal. the elements in the modal are mainly shells and beams
這四家船級社相同之處是都採用了船舯附近的兩艙段長的有限元計算模型，有限元模型單元的劃分主要依據縱骨間距和肋距，即所謂的細網格模型，結構單元以板殼單元和梁元居多。 -
At this time, the approximate mechanical model of devices has been put forward, which frequency is 70 mhz, then we analyzed the euler ? bernoulli equation, find that the frequency is determined by the resonator ’ s density thickness and length ; the free - free - beam 、 coupled beam 、 support beam 、 transducer have been designed ; the model was simulated and modal analyzed on the coventorware and were consistent with the designed parameter. the silicon surface microfabrication process was developed and emphatically introduced several key surface microfabrication technologies, and was simulated by coventorware
本文通過分析歐拉-貝努立方程，得出濾波器的共振頻率主要由諧振梁的密度、厚度和長度決定，考慮切變形和轉動慣量的情況下，完成微機械諧振梁、支撐梁、驅動電容的設計;在coventorware軟體上進行模擬，分析結果與理論設計比較好地吻合;對微機械濾波器的加工工藝進行設計，給出器件的完整的工藝流程，重點介紹微機械表面加工工藝，並在coventorware上進行模擬。 -
The optical switch with double - heterostructure gaas / gaalas has low switching - voltage and light loss. and the boa - type optical switch utilizes maximum modal dispersion ( a p ), does not require a specific fabrication length or length range to operate, has simple structure, and can exhibit very high extinction - ration from its two output ports ; so it is suitable for a 2 x 2 unit of optical switch array
而boa型結構（或稱為零間隙定向耦合型）光開關利用了最大的模色散（ ） ，不需要嚴格控制特殊的製造長度或製造范圍，結構簡單，從其兩個輸出端可以得到很高的消光比，是一種很好的2 2波導型光開關單元，同時也是光開關陣列的一種較好的選擇。 -
And then based on this modal, some classic algorithms such as a * algorithm, are analyzed. in the process of the realization of the a * algorithm, an appropriate function, which can find the best route in according to the flow time and the length is always playing the great role. lastly, the essay concludes what have done mainly during this development process and the effectiveness of the study
文中從城市道路網路的特點出發，分析了道路路段間的連通關系，建立了一個合理的網路拓撲模型，然後分析這個網路拓撲模型以及一些經典的演算法，依據a *演算法的思想，構造了合理的啟發函數，從而根據流量、時間、距離等參數求出源點到目的節點的最優行車路線。 -
We build some flexible projecting beam finite element modal with different crack. through studying vibration characteristics of different flexible projecting beam modal, what has different length crack on different position, we can research tie influence of the position of crack and the length of crack. then we make an experiment on the vibration of the flexible projecting beam
為了討論裂縫所處位置、裂縫長度對柔性懸臂梁振動特性的影響，在樑上選取了7個不同位置，並在每個位置上設定了7種裂縫長度，建立了49根的柔性懸臂梁的有限元模型。 -
The modal analysis result shows that the vertical and horizontal frequencies of dps undeployed are high enough and suffice the dynamic stiffness requested for launching. but the large spread length and light weight effect the low frequency of dbs deployed, so considerations should be taken to the effects of other systems of the satellite. the static analysis result shows that the displacements of the dbs are small under the joint affect of vertical and horizontal loads, and stresses are low, so the stiffness and intensity are good enough
模態分析結果表明伸桿收攏狀態的軸向和橫向頻率都比較高，可滿足發射升空時的動剛度要求；靜力分析結果表明伸桿結構在衛星處于發射段和上升段時，在軸向和橫向過載聯合作用下變形均較小，剛度足夠；其應力水平亦較低，強度儲備較大。 -
Then, we got the general conclusion by combining theory analyze and practice this question for study puts forwards new modal of teaching set, school - based environment by using the theory study method, positive study method and comparative study method, whose main purpose is to strengthen the environment education in the middle school of small towns in the concrete school environment on the base of the best use of school resources and local social environment it ' s proved that it greatly improves the length of limitation period and actual practical behavior it is good to develop the students " principal partivities, cultivates the students " active study
最後，文章結合理論分析與教育實踐得出了一般性教學結論，並提出了下一步的教學建議。本課題用原理研究法、實證研究法和比較研究法，提出校本環境教育這一新的模式，目的是在充分利用學校資源、社區資源的情況下，在具體的學校情景中加強小城鎮高中的環境教育。通過實踐證明，它明顯地提高了環境教育的時效性和實效性，強化了學生的實踐行為，利於學生主體性的發揮、主動探究性的培養，同時也有效地提高了教師責任、素質和科研意識，使教師的角色發生變化。
