Based on extensive investigation of construction technique history of chinese ancient buildings, the structure method, structure developing history and seismic behavior of chinese ancient timber structure buildings are analyzed in several respects of the structural system and form. through a series of experiments on constituent parts of chinese ancient timber building structure, including the tests on the corbels and brackets called dougong subjected to low cyclic reversed loadings, the tests on the wooden frame using the tenon - mortise joints as connections of column and beam subjected to low cyclic reversed loadings, the tests on vibration isolation effect of friction and slippage between column footing and their socle base, and a series of shaking table tests on a chinese ancient timber structure palace building mode under artificial earthquake at serving conditions, destroyed conditions and reinforced conditions, many valuable results of structures such as moment - curvature hysteretic loops of dougong structure and tenon - mortise joints under low cyckc reversed loadings, the static function, the seismic performance, energy dissipation, vibration reduction, energy - loss mechanism, nechanicalmode and failure mode were studied. aplenty of valuable parameters of the structure system were obtained, such as the natural period of structure, vibration modes, damping ratio, factor of vibration isolation, oscillate amplitude of ineitial accebration, velocity and displacement, magnitude of slippage, and the mechanism of structure failure and collapse etc. based on these research, the complete analysis of ancient timber structure under earthquake were carried out in which including mechanism analysis method, calculating mode, strength analysis of members and joints, strengthening methods for serving damaged ancient timber structure buildings were also taken into account
依照宋代《營造法式》建造了抬梁式殿堂木結構構件及結構模型，對中國古代木結構中的典型構造如：柱腳在礎石頂面平擱簡支、柱架榫卯連接、柱高不越間之廣、側腳、生起、斗拱等的構造機理及結構功能進行了量化分析和實驗研究： （一）通過木柱石礎靜摩擦試驗，測定了柱腳與石礎古鏡面間的摩擦系數及摩擦力隨上部結構荷載變化的規律； （二）通過單柱承載力試驗，測定了古建築中木柱的受力變形特徵、破壞模式、及模型材料的變形模量、極限承載力、極限變形等參量； （三）通過柱架低周反復荷載試驗，測定了柱架的抗側移剛度、柱架恢復力特性及滯回曲線、榫卯張角剛度及其變化規律、柱架及榫卯的極限承載力和極限變形、及榫卯減振參數； （四）通過斗?低周反復荷載試驗和受壓試驗，測定了古建築木構件與木構件間摩擦系數，斗?抗側移剛度，斗?恢復力特性及滯回曲線，斗?抗壓極限承載力及受力變形規律； （五）通過抬梁式殿堂間架模型振動臺試驗，測定了殿堂木構架結構自振周期，地震反應振形、阻尼特性及阻尼比；按結構分層特點對柱腳、柱頭和斗?層上的屋蓋的地震反應採用多點同步測量，對柱根滑移、榫卯變形、斗?的變形、復位、耗能減振參數等進行了定量分析。 -
For the situation of many heavy accidents in process of the gypsum mineral deposit underground mining in our country now, the dangerous and hazardous factors are analyzed and the worked - out section collapse is considered as the most important dangerous factor
摘要本文針對當前我國石膏礦床地下開采過程中重大特大事故不斷的局面，分析了石膏礦床地下開采過程中存在的危險危害因素，指出采空區大面積坍塌是當前我國石膏礦床地下開采過程中最重要的危險危害因素。 -
Now many researches have attributed the decline of rural area ' s medical service to the collapse of the " the rural cooperative medical system ", but from the research in gan zi prefecture the author think the main reason is the change of the rural - urban dichotomy structure and the more market - oriented factor appearing in the medical system since 1980 ' s
現有的農村醫療衛生研究大多把目前農村中的醫療衛生出現的情況歸結為合作醫療的破裂，本文通過對甘孜州的研究認為，從80年代以後中國城鄉二元結構的變動與醫療體制中市場因素的出現才是問題的根本原因。 -
The results show that the light field is squeezed regularly, and that the collapse - and - revival of the atomic rabi oscillation appears under the detuning. when the initial squeezed light - field factor r is weak, photon bunching alternates with photon antibunching, and the detuning leads to the reduction of photon antibunching ; to the contrary, the factor r is strong, photon statistical properties are steady bunching, and the detuning makes two - mode correlation properties steady
數值計算結果表明：光場呈現出較規則的壓縮現象；失諧量使原子rabi振蕩呈現周期性崩塌與復甦現象；當r較小時，光子的聚束效應與反聚束效應交替出現，失諧量將削弱光子的反聚束效應；當r較大時，光子呈現恆定的聚束效應，失諧量增強光場兩模非經典相關的穩定性。 -
The collapse mainly occurs in the low - water years or during the beginning of the dry season and rain season in a year. the formation and developing scales of the collapse are affected by many factors, such as karst caves, sola and water, etc. however, the taking of the underground water which causes the hydrodynamic conditions changed and the water level highly descended is a leading factor for the karst collapse. the mechanism of karst collapse is discussed based on long - term monitoring results of groundwater level and geological environment
塌陷的產生與發展規模受溶洞、土層和水等多種因素的綜合影響，但過量開采地下水導致地下水動力條件急劇改變或水位大幅度下降是造成塌陷形成的主導因素;進一步討論了泰安市巖溶塌陷的形成機理，在此基礎之上對泰安市巖溶塌陷的監測預報及對土地資源管理利用的影響進行了研究，並根據當地的防治實踐，提出了巖溶塌陷防治的對策建議。 -
This dissertation offers an explanation from a special angle, which focuses on the strategy of peaceful evolution of the united states in poland and the collapse of polish communism, so as to show an important external factor of the collapse of polish communism and the eastern europe communism as a whole
對東歐社會主義國家劇變原因的探討，是冷戰結束后學術界探討的一個熱門課題。本文從一個獨特的視角- - - - -美國和平演變戰略與波蘭社會主義滅亡的角度出發，揭示波蘭乃至整個東歐社會主義滅亡的一個重要的外部因素。 -
