This paper has mainly made a research on the aerodynamic configuration design of " w " tailless aircraft and the design idea has been presented here. according to the configuration design requirement of certain uav, aerodynamic configuration design has been carried out and two configuration projects are given out at last : forward - swept wing tailless configuration and " w " tailless configuration. the longitudinal and lateral aerodynamic characteristics are obtained by using two aided soft : ug to build up geometrical models and mgaero to calculate flow field
本文研究了「 w 」型無尾布局的氣動外形設計，闡述了該布局的氣動設計思想，根據型無人機的總體設計技術指標，進行了氣動外形設計，提出了兩種氣動布局方案：前掠翼無尾氣動布局和「 w 」型無尾氣動布局，利用ug建模軟體和mgaero氣動分析計算軟體計算了兩種布局的縱、橫向氣動性能，分析了前掠翼前緣掠角和翼身融合對氣動性能的影響，計算結果表明， 「 w 」型氣動布局的設計思想是正確的，所設計的「 w 」型無尾氣動布局方案的氣動性能優越，超過了總體設計技術指標。Since the implementation of train speed - lifting program of railway department, both car and bridge dynamic function to the train running on the bridge has become a more important issue, in particular because of the insufficient strength and rigidity of part of bridge ' s horizontal structure, the horizontal vibration has topped the main obstacle to speed - lifting when rustling train passing the bridge
隨著鐵道部提速戰略的實施，車橋動力作用對橋上運行列車的影響已越來越受到人門的重視，特別是由於部分橋梁橫向剛度不足使列車高速通過時橋梁結構橫向振動幅度超標已成為列車提速的主要障礙。Because of the original design standard was low, the horizontal angur rigidity is serious lack, when the high speed train passes, the exceed limit of the horizontal swing had affected the lifting of the main trunk line, these diseases had been existed earlier but had not been gotten to resolve radical, and along with the increasing in speed of railroad train, these diseases performance will be more seriously, it ' s time for resolve
同時提速列車對橋梁結構的動力作用增大，特別是對上承式鋼板梁。由於原設計標準低，橫向剛度嚴重不足，高速列車通過時橫向擺動嚴重超限等已嚴重影響了主要干線的提速，這些病害很早就存在但沒有得到根治，隨著列車提速，這些病害表現越來越嚴重，已到了必須整治的時候了。Because of its many advantages, the tapered portal frame is getting more and more application. ( ( technology code of light steel structure of portal frame ) ) ( cecs 102 : 2002 ), our country enacted, does n ' t define conditions that tapered portal frame needs anti - earthquak - e design. but mentions in illustration of rules : when earthquake fortification intensity is 7 degree, the portal frame does n ' t need anti - earthquake checking generally ; but for 8 degree and above, horizontal just with lengthways frames both need anti - earthquake checking
楔形變截面門式剛架山于其諸多的優點得到越來越廣泛的應用，我國頒布的協會標準《門式剛架輕型房屋鋼結構技術規程》 （ cecs102 2002 ）中沒有對變截面門式剛架需要進行抗震設計的情況進行具體規定，但在後面的條文說明中提到： 「當抗震設防烈度為7度時，一般不需做抗震驗算；當為8度及以上時，橫向剛架和縱向框架均需做抗震驗算。 」Abstract : artifical intelligence methods are implemented to simulate thebehaviors of axially and laterally loaded piles using the field observation tests data obtain ed f rom the drilled shafts and driven piles. the optimal neural network model is deve loped using only simple input data of spt - n values and piles ' geometrical featu r es etc. the analysis for r. c piles of some projects is performed adopting the bp n n and grnn models respectively, and the obtained predicated results are compared w ith the data from conventional design method. it demonstrated the obvious advanta ges of neural networks in the design of pile foundations over the traditional me thods. this paper has an important practical significance and a referential worth iness in the design of pile foundations
文摘:根據鉆孔樁和打擊樁的原型試驗觀測的數據，運用人工智慧方法對橫向承載樁和軸向承載樁的工作特性進行模擬，並利用標準貫入試驗（ spt - n ）值和樁的幾何特性等簡單的輸入數據，開發出相應的優化神經網路模型;然後，運用反向傳播神經網路模型和廣義回歸神經網路模型分別對某工程的鋼筋混凝土樁進行分析，並將求得的預測結果與常規設計法的結果進行比較，結果表明神經網路方法比傳統方法有明顯的優越性，在實際工程設計中具有重要的參考價值和現實意義。The results show that the higher the wind velocity is, the faster the concentration of the pollutants will attenuate after the pollutants leave the tunnel portal ; while the transversal wind will result in the higher concentration of pollutants in a large range around the tunnel portal
計算結果表明，風速越高，廢氣離開峒口后，濃度衰減得越快；而橫向風則會導致隧道兩側很大區域內的污染物濃度超標。Whenever wes brown, paul scholes, darren fletcher or michael carrick ( see diagram ) had possession to the right of the middle third, they looked to ping the crossfield ball to the left flank where ronaldo ' s running skills had been earmarked as a threat
無論何時布朗、斯科爾斯、弗萊徹或卡里克在三人中場的右面取得控球權后，他們都會把球橫越過球場地傳到左路去，正因為羅納爾多邊線奔跑的本領正是他造成威脅的標記。A line of springs that ran through the sanctuary and intersected the temple marked the location of the kerna fault below the ancient terracing and the accumulated debris from rockslides
