Based on the review, the fluid flow and heat transfer in the curved circular and rectangular pipes have been researched by employing perturbation method and numerical simulation with a physical model under the rotational orthogonal curvilinear coordinate in a rotating curvilinear pipe with multi - parameters. we firstly analyzed the fully developed fluid flow and heat transfer, mixed convection heat transfer, the development of flow and heat transfer in the inlet in different cross section ( circular, elliptical, annular and rectangular crossection ). the variations of the secondary flow, axial velocity, distribution of temperature, the friction force on the wall, the ratio of friction factor as well as the nusselt number with different dimensionless parameters had been examined in detailed
本文在總結和分析了一個世紀以來有關曲線管道流動和換熱特性的研究成果的基礎上，以旋轉正交曲線坐標系統下的多參數旋轉螺旋管道中的對流傳熱為物理模型，通過攝動方法和有限體積法，首次對各種截面（圓截面、橢圓截面、環形截面、矩形截面）旋轉曲線管道內充分發展流動的流動結構和傳熱特性（包括耦合對流傳熱特性）以及旋轉曲線管道開口段發展流動的流動結構和換熱特性進行了系統的數值模擬和理論分析，詳細討論了各種無量綱參數對管道內軸向速度分佈、二次流結構、溫度分佈、壁面摩擦力、摩擦系數比以及管道nusselt數的影響，獲得了若干創新性成果。 -
In this paper, we first analyze each factor of influencing threshing performance, and deficiency of all traditional methods such as single factor, orthogonal experiment, variance analysis and regression analysis, which have been used to study the threshing performance. in the basis of above analysis, we propose a new method of threshing performance modeling - a bp neural network. by use the new ways of threshing performance modeling - a bp neural network, we can obtain the optimum model of threshing performance, which can better describe the seed - husking plant ' s feature of complex nonlinear, multi - input - output and indefinite
本文首先分析了影響脫粒裝置性能的各個因素以及傳統研究脫粒性能的各種方法如單因素法、正交試驗法、方差分析法以及回歸分析法的缺陷，在此基礎上提出了採用bp神經網路對脫粒裝置性能模型進行優化，採用這種方法優化脫粒裝置性能模型可以更好地刻劃脫粒裝置所具有的多輸入多輸出、復雜非線性以及不確定性等特徵。 -

Bearing capacity and displacement are two main problems in the application of geotechnical engineering. based on a series of pull - out tests using three kinds of paper and a sort of window screening as geogrid, twenty - seven in limit and several in working - stress geogrid - reinforced slope model tests designed through orthogonal principle have been conducted to have obtained the relationship between the bearing capacity and four factors ( i. e. reinforcement, angle of reinforced slope, the designed - length of reinforcement and the distance between layers of reinforcement ). the law of slope lateral ( horizontal ) displacement versus to the height of slope vary with external - load was derived from the model test data, and the main factor affecting the lateral and vertical displacement of geogrid - reinforced slope was obtained through analysis
承載力（強度）和變形是巖土工程應用領域的兩大主要問題，本文以紙和窗紗布模擬加筋土邊坡的土工格柵，在一系列拉拔試驗的基礎上，以正交設計理論分別安排27個極限應力狀態和若干個工作應力狀態加筋土邊坡模型試驗，並以模型試驗獲得的數據為依據，採用誤差、極差及回歸分析方法，探討了加筋土邊坡承載力與筋類、筋長、層間距、坡角4因素的相關關系，獲得了在外荷載作用下加筋土邊坡的側向位移隨坡高的變化規律（並進行了定性解釋）和坡頂的豎向位移特性，並分析其主要控制因素。 -
