beam sides 中文意思是什麼
-
So the circumjacent welding should be applied at this spot and another join symmetrical to it, all sides of the place at which angle iron join are welded around with the main beam
因此應該在該位置以及與之對稱的另一聯接點處都應採用周邊焊，使角鋼連接處的各邊全部焊接，然後再與大樑周邊焊接。 -
In order to make the sensitivity of 2 - demension accelerometer along the two main arbors almost identical, symmetric four - beam structure that embeds a double - sides interdigitated differential capacitive with puckered beam in two directions was used as sensitive component. in addition, the differential capacitive accelerometer fabricated by bulky silicon micromechanical technique has high sensitivity, wide measurement scope, less nonlinear error, and simple converting circuit. then, the structure parameters of the sensitive component were calculated and stimulated, which results in a set of the optimized structure design parameters, main fabrication procedure and several key fabrication technology
為使二維振動傳感器在兩主軸方向的靈敏度大致相同，敏感元件採用高度對稱的四梁結構，其中每個軸向上均採用帶折疊梁的雙側叉指電容結構，採用體硅微機械工藝製作的高深寬比叉指電容式敏感元件，具有高靈敏度、寬量程、非線性誤差小、外圍電路簡單等優點;對設計的敏感元件結構參數進行了計算，並利用有限元法進行了模擬分析，根據模擬結果得出了優化參數;在確定敏感結構的基礎上，研究了敏感元件採用體硅微機械加工工藝製作的工藝流程和關鍵工藝技術;對敏感晶元內部的c - v介面電路進行了原理設計與分析，利用差動測量技術得到由振動引起的微小電容變化量，經c - v介面電路進行相位調制處理，然後通過解調輸出與加速度成正比的電壓信號。 -
Taking the sucessful control experiences in previous cable - stayed bridge construction into consideration, the control principles and methods for gonghe bridge, that is controling the stress of both the top and bottom sides of main beam, regarding the second stretching as the hauling cable force method, are offered, and related construction procedures for all construction stages are designed
在總結前人對斜拉橋施工控制經驗的基礎上，針對公和斜拉橋施工控制提出了相應的控制原則和方法，即以「控制主樑上下緣應力」為主梁內力控制原則，以「二次張拉」為斜拉索索力控制的方法，並根據各施工階段的具體需要設計相應的施工步驟。 -
The wall is easily detected from space by radar because its steep, smooth sides provide a prominent surface for reflection of the radar beam
城墻很容易被雷達探測到，因為城墻的豎直光滑的平面提供了一個反射雷達波束的突出表面。
