他曾是一隻高傲的翼龍，由於被惡毒的鳥身女妖女王以非生命的型態帶回塵世，而轉變為擁有過去外型的米里吉。In this thesis, four types of steel beam - rectangular cfst column connections, including normal welded flange plate ( wfp ) connection, bolted flange plate ( bfp ) connection, stiffened end plate ( sep ) connection and double split - tee plate ( dst ) connection, were designed based on the configuration of steel frame connection. total 8 models, 2 models of each kind of connections were tested under low - reversed cyclic loading at the end of cfst columns. the relationships between force and displacement at the end of columns, the relationships between the moment and rotation of the joints, degradations of strength and stiffness, ductility, failure mechanism and failure characteristics of these four connections under different axial - compression ratios were presented
本文借鑒鋼框架節點構造，設計了四種類型矩形鋼管混凝土柱與鋼梁連接節點，包括常規栓焊（ wfp ）節點、翼緣全螺栓連接（ bfp ）節點、雙t板連接（ dst ）節點以及加勁端板連接（ sep ）節點，進行了四類節點8個模型試件在柱端低周反復荷載作用下的抗震性能試驗研究，比較了不同軸壓比下節點的滯回性能、強度與剛度退化、延性、破壞機理與破壞特徵，主要結論有： 1 、節點的位移滯回曲線與轉角滯回曲線為塊型分佈，沒有或略有捏攏現象，耗能能力強； 2 、軸壓比對節點滯回曲線有顯著影響，全部節點都有顯著的剛度退化； 3 、位移與轉角骨架曲線在峰值荷載後有較長的水平或下降段，具有良好的延性性能； 4 、從整體抗震性能上看，翼緣全螺栓連接節點、雙t板連接與加勁端板連接節點都優于常規栓焊節點，可在實際工程中加以推廣。The main work in this paper includes three parts : the theory research on partially - cavitating and super - cavitating axisymmetric bodies, the numerical computations and experimental investigations on partially - cavitation and super - cavitation on axisymmetric bodies. after finishing the study of theory and experiment on the partially - cavitation and super - cavitation for axisymmetric body, i use the potential flow theory to build the mathematical model on the partially - cavitation and super - cavitation for axisymmetric body. many cavity wake models, such as pressure recovery close model, riabouchinsky model and re - entrant jet model, are studied seriously
本文在深入研究了回轉體局部空化與超空化理論及實驗結果的基礎上，基於勢流理論，建立了回轉體局部空泡和超空泡流場的基本數學模型，通過對kinnas和fine 、 uhlman以及jiedang和gertkuiper等人基於二維水翼提出的壓力恢復閉合模型、鏡像板模型和回射流模型等空泡尾流模型進行了逐一的研究分析，發現其中的壓力恢復閉合模型較適用於模擬回轉體空泡尾部流場，並選用此空泡尾流模型作為求解回轉體空化流場正問題與逆問題的數學模型的組成部分。It is mainly made up of lognitudinal framework, latitudinal framework, airfoil shell, tie - in etc. for the frp airfoil shell, we generally use moulding method of handcraft laying
飛機機翼曲面是一個結構復雜的非回轉曲面，其整體結構主要由縱向骨架、橫向骨架、蒙皮和接頭等構件組成。With the helicopter hovering at a safe altitude, roll the helicopter to the left, until the rotor blades are vertical, the helicopter must remain horizontal during this maneuver, drop collective and add forward cyclic
先將直升機停懸在安全的高度，然後將副翼打左舵執行1 / 4側滾，直到主旋翼回轉面成為垂直，機體必須保持水平，降低主旋翼的螺距成為0 ，並且將升降舵打降舵。分享友人
