This paper presents the structural design of the main bridge of lhasa river bridge, makes a deep - going study of the key techniques for design of the bridge, such as the reasonable span length ratio of each span of the 5 - span girder and arch hybrid structure, mechanical behaviour of the dual arch ribs, and section of the continuous girder tie beam, and also works out rigidity and stress conditions of the continuous girder tie beam and stress conditions of the concrete - filled steel tube arches of the main bridge
摘要介紹了拉薩河特大橋主橋結構設計情況，對於五跨梁拱組合橋梁各孔跨合理的跨度比、疊拱的受力行為及連續梁系桿截面形式等設計中的關鍵性問題進行了深入的研究，給出了主橋連續梁系桿的剛度和應力情況、鋼管混凝土拱的應力情況。 -
Hybrid wave mode control of timoshenko beam vibration
梁的行波與模態的混合控制方法 -
Since it is difficult for the cable or beam model to consider the large deformation in the pipe crossing section, the fem analysis with shell element has been proposed to investigate the response of pipe. takada ( 2000 ) proposed a simplified design formula to obtaining the maximum strain in steel pipes based on the parametrical study using a beam - shell hybrid fem
現在的抗震規范和有關研究中，還很少有估計大變形時管子內的應力應變的方法，雖然2000年高田至郎等人基於殼有限元模型的參數研究提出了設計用的簡化計算公式，但在他們的分析模型中存在一些問題有待改進。 -
Secondly, based on the analysis of the relationship between the processing tasks, a hybrid algorithm combined the filtered beam search algorithm with the local search algorithm is proposed
其次，在對工序任務之間的邏輯關系深入分析的基礎上，提出一種基於過濾束演算法思想與基本鄰域搜索演算法相結合的混合演算法。 -
The paper did scrupulous discussion and investigation on the interaction between electron beam and standing wave field in the gyroklystron, which is typical in the electron cyclotron maser which action rf system is resonant cavity. the main works of this dissertation are listed as following : first, solving field in absorbing material and field matching method were used to derive the dispersion equation in waveguides and field matching formulas of hybrid modes in an abrupt cavity with absorber. based on the theoretical analysis, numerical simulations of the cavities in gyroklystron were done
主要工作有:一、採用吸收介質分區求解及場匹配的方法推導出含有吸收層的色散方程，單側加入吸收介質及兩側均加入吸收介質兩種突變結構混合模場的匹配方程，在理論分析的基礎上，通過相關的模擬軟體，建立了迴旋速調管介質加載中間腔的計算模型，對迴旋速調管中間腔進行了數值模擬，並給出了主要的計算結果。
