  2. Abstract : biological invasions are a continuous feature of a non - equilibrium world, ever more so as a result of accidental and deliberate introductions by mankind. while many of these introductions are apparently harmless, others have significant consequences for organisms native to the invaded range, and entire communities may be affected. here we provide a survey of common models of range expansion, and outline the consequences these models have for patterns in genetic diversity and population structure. we describe how patterns of genetic diversity at a range of markers can be used to infer invasion routes, and to reveal the roles of selection and drift in shaping population genetic patterns that accompany range expansion. we summarise a growing range of population genetic techniques that allow large changes in population size ( bottlenecks and population expansions ) to be inferred over a range of timescales. finally, we illustrate some of the approaches described using data for a suite of invasions by oak gallwasps ( hymenoptera, cynipidae, cynipini ) in europe. we show that over timescales ranging from 500 10000 years, allele frequency data for polymorphic allozymes reveal ( a ) a consistent loss of genetic diversity along invasion routes, confirming the role of glacial refugia as centres of genetic diversity over these timescales, and ( b ) that populations in the invaded range are more subdivided genetically than those in the native range of each species. this spatial variation in population structure may be the result of variation in the patchiness of resources exploited by gallwasps, particularly host oak plants

    文摘:生物入侵是不均衡世界的一個永恆話題,尤其是當人類有意或無意地引入物種后.很多引入顯然是無害的,但另外一些則有著嚴重的後果,會給入侵地的生物以至於整個生物群落造成影響.本文總結了分佈區擴張的常見模式,概述了它們對遺傳多樣性和種群結構式樣所造成的影響.描述了如何根據以一批遺傳標記所得到的遺傳多樣性式樣來推斷入侵途徑,來揭示伴隨擴張選擇和漂變在形成種群遺傳樣式中的作用.本文對日益增多的群體遺傳學方法進行了總結,這些技術可以用來在不同的時間尺度上推斷種群規模所發生的巨大變化(瓶頸應及種群擴張) .最後,我們以歐洲櫟癭蜂(膜翅目,癭蜂科,癭蜂族)一系列入侵的數據為例對一些方法進行了說明.從500 10000年的時間尺度上,多態的點上頻率的數據表明: 1 )遺傳多樣性沿入侵路線呈不斷下降的趨勢,支持了冰河期避難所作為遺傳多樣性中心的作用; 2 )入侵地區的種群與該物種原產地的種群相比,遺傳上的分化更為強烈.這種種群結構在空間上的變可能是被櫟癭蜂開發的資源尤其是櫟樹寄主在斑塊上出現變的反映
  3. Under the horizontal earthquake action and wind force, aim at " the pure frame structure with rectangle columns ", " the pure frame structure with special - shaped columns ", " the frame - truss structure with special - shaped columns " and " frame - shear wall structure with special - shaped columns ", earthquake action analysis was done by the spacial finite element method through the changes structural parameter. analyzing systematically " structure vibration mode ", " vibration period ", " structure lateral rigidity ", " seismic action force ", " seismic response force ", " floor seismic shear force ", " lateral horizontal displacement of structure " and " members internal force ". results indicate : ( 1 ) based on equal area, the special - shaped columns replaced the rectangle columns, the structural lateral rigidity enlarges, the lateral displacement minishes obviously, the earthquake response increase slightly, the biggest increasing amount of frame columns axis - compress ratio is smaller than 0. 08. the whole aseismic performance of structure has improved ; ( 2 ) when the section ' s length and section ' s thickness ratio of special - shaped columns is smaller than 3. 6, the structure benefits to resist seismic action ; ( 3 ) the angle of horizontal seismic action with the whole coordinate is 0 degree, structure earthquake response is bigger, belonging to a control factor of structure aseismic design ; ( 4 ) the frame - truss structure with special - shaped columns and the " a " - brace has the biggest lateral rigidity ; ( 5 ) the frame - shear wall structure with special - shaped columns have bigger lateral rigidity and smaller displacement, members internal force enlarged just rightly, have much superiority of resisting seismic action ; ( 6 ) in the higher seismic fortification criterion region ( 8 degree of seismic fortification intensity ), aseismic disadvantageous building site ( iii type site ), adopting special - shaped columns structure system, should reduce possibly the building ' s self - weight in order to reduce the earthquake response ; ( 7 ) the response spectrum method of computing seismic response and the time - history analysis method have similar analysis result

    西安理工大學碩士學論文在水平地震作用下,並考慮風荷載組合,分別對「矩形柱純框架結構」 、 「型柱純框架結構」 、 「型柱框一析架結構」及「型柱框-剪結構」四種結構體系,通過改變結構參數,運用空間有限元方法,進行地震作用計算。系統地分析研究「結構振型」 、 「振動周期」 、 「結構側向剛度」 、 「結構地震反應力」 、 「樓層地震剪力」 、 「結構側向移」 、 「層間移角」 ,以及「構件內力」 。結果表明:在面積原則下,型柱代換矩形柱后,結構剛度增大,側向移明顯減小,地震反應力略有增加,框架柱軸壓比最大增幅小於8 % ,結構整體抗震性能有所提高;當型柱肢長肢厚比小於於3 . 6時,結構有利於抗震;水平地震作用力與整體坐標夾角為0度時,結構地震作用應較大,屬結構設計的控制素之一;型柱框一析架結構採用「人」字斜撐,側向剛度大於「八」字斜撐和「人一八」字混合斜撐;型柱框一剪結構側向剛度大、移小,構件內力增大適中,是一種抗震性能優越的結構體系:在抗震設防烈度較高地區( 8度)和抗震不利的建築場地( m類場地) ,採用型柱結構體系時,應盡可能減輕結構自重,降低地震作用力;分別採用「振型分解反應譜」法和「時程分析」法進行地震作用計算,兩種方法所得結果本一致。
