offset beam 中文意思是什麼
offset beam
解釋
偏移波束-
The angle spectrum of inputting optical signals is received by the input surface of arrayed waveguides. whereas the diffraction process of light beam outputed in slab waveguide is a process of " composing frequency and generating image ". the reason that fraunhofer diffractive pattern can be gained on outputting waveguide surface is that output ends of arrayed waveguide distribute on the arch structure which leads bent phase factor to offset the quadratic phase factor in fresnel diffraction
輸入平板波導內光束的衍射過程是「分頻成譜」的過程，在陣列波導的輸入面接收到的是輸入光信息的角譜；而輸出平板波導內光束的衍射過程則是「合頻成像」的過程，正是由於陣列波導輸出口排列分佈在圓弧形結構上，其彎曲位相因子消去了菲涅耳衍射中的二次位相因子，從而在輸出波導面上能夠得到夫瑯和費衍射圖樣。 -
At the last of this paper, we summarized the deficiencies of simulating pre - stressing anchor and proposed the new and accurate simulating method which is given up the traditional tow points applied forces and applied a point reverse forces, made beam element simulate the anchor bolt, made interface element simulate concrete. in addition, we proposed two simulating methods applied on flock anchors which improved on considering the contribution of anchors " tangent - orientation stiff. one is post - stressing offset method ; the other is anchor element method
另外，本文還提出了兩種改進原有群錨模擬中沒有考慮錨索限制變形的側向剛度貢獻的方法，即后續張拉補償法和錨索單元法，通過平面直線型滑動破壞中這兩種方法與傳統群錨的兩點集中力法的比較、分析，表明這兩種方法的結果與實際情況較為相符。 -
Next, a three - span curve continuous box beam has been studied by fem, and how to set the single - pedestal pier in curve continuous box beams has been discussed. when setting the single - pedestal pier, the vehicle flow should be inspected firstly, and then a best offset distance should be selected within the feasible range of the offset distance. meanwhile, increase the spacing interval of the double supports to the largest extent when installing a double supports on a sharing single - pedestal pier, which can enhance the stability and security of the bridge as a whole
對上石立交橋中一座三跨連續的曲線箱梁進行有限元分析，詳細地討論了在曲線箱梁中如何合理設置獨柱墩的問題，分析表明獨柱墩的設置應該根據車流調查的實際情況，再結合結構本身的特徵，在可行的偏距范圍內選擇一個最佳的偏距，另在對公共墩上的雙支座進行設置的時候應該盡量使雙支座的間距增大，這樣可以保證橋梁整體的穩定性和安全性。 -
Secondly, the beam orbit offset effects caused by the initial beam offset and the linac components " offsets have been quantitatively studied first. as an example with the injector linac for beijing electron positron collider upgrading project ( bepcii ), the beam orbit offset caused by the above error effects have been simulated and analyzed
其次定量研究束流的初始徑向誤差和加速器部件的安裝誤差等對束流軌道偏軸的影響，並以北京正負電子對撞機二期工程（ bepc ）的直線加速器為例，給出了上述各種誤差導致軌道偏軸的模擬計算結果及其分析。
