  1. Present methods generally based on the statistics of earthquake damage, expert experiences, theory analysis and experimental researches have obvious advantages, disadvantages and certain scopes of application ; ( 2 ) different prediction methods should be adopted against different building conditions, sites, intensity and experiences etc to predict earthquake damage of buildings for prospective accuracy, dependability and availability ; ( 3 ) earthquake damage matrix, which is the foundation of earthquake damage prediction, of 7 kinds of building in the urban areas of zhangzhou city under intensity 6 to 9 has been set up. the damage conditions of different buildings under different intensity are as followings : all kinds of structures are basically intact under intensity 6 ; the reinforced concrete structures are basically intact under intensity 7, but other kinds of structures are destroyed slightly ; the reinforced concrete structures are still basically intact while other kinds of structures are destroyed intermediately under intensity 8 ; the reinforced concrete structures are destroyed slightly, single - story factories and open houses are destroyed intermediately and other kinds of structures are destroyed seriously under intensity 9 ; ( 4 ) the results of earthquake damage predicting of buildings embody the damage when earthquake happens in the future. thus, further identifications and reinforcements should be considered to buildings that will be destroyed intermediately or more under the earthquake with 10 % exceeding probability in future 50 years ; ( 5 ) the direct economic losses caused by damage of buildings resting with the area, structural type, intensity and damage of all kinds of buildings are the main part of the losses of the city in an earthquake ; ( 6 ) the direct economic losses increased progressively toward high intensity by 2 or 3 times

    基於上述研究，得出的主要結論有：建築物震害預測是一個模糊的、系統的、復雜的問題，現有的方法很多一般都是以震害統計規律、專家經驗、理論分析和試驗研究為依據，有其自身的優缺點和一定的適用范圍；應針對不同的建築物條件、場地條件、地震強度和已有經驗等，採用不同的預測方法進行建築物震害預測，以使預測結果達到預期的精確性、可靠性和可操作性；建立了漳州市區7類建築物在6度9度地震作用下的震害矩陣，成為指導抗震防災的重要依據，各類結構的震害情況表現為： 6度地震作用下各類建築物基本完好； 7度地震作用下除鋼筋混凝土結構基本完好外其餘以建築輕微破壞為主； 8度地震作用下鋼筋混凝土結構仍以基本完好為主而其餘建築以中等破壞為主； 9度地震作用下鋼筋混凝土結構以輕微破壞為主，單層工業廠房和空曠房屋以中等破壞為主，其餘建築以嚴重破壞為主；建築物的震害預測結果體現了未來地震來臨時的震害程度，在編制漳州市區抗震防災規劃時，對于遭遇50年超越概率10的地震影響發生中等以上破壞的建築物應考慮進行抗震鑒定和加固；由建築物的破壞所造成的直接經濟損失是城市地震經濟損失的主要部分，重慶大學碩士學位論文中文摘要其主要與建築物總面積、結構類型、地震烈度和各類建築物的震害程度有關;不同烈度造成的直接經濟損失按2一3倍向高烈度方向遞增，漳州市區直接經濟損失由6度至9度的比例關系為1 : 2 . 8 : 8 . 6 : 22 . 8 ;遭遇基本地震設防烈度（ 7度）時，漳州市區直接經濟損失約4 . 5億元，無家可歸人員約40000人，且以磚木結構和多層磚混結構的震害損失最大;地震造成的人員傷亡主要與建築物倒塌及嚴重破壞的程度和總面積以及震時的建築物室內人數密切相關，地震時無家可歸人員主要與住宅倒塌、嚴重破壞及中等破壞的程度和總面積以及城市人均居住面積密切相關。
  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（瓶頸效應及種群擴張） .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，多態的等位酶位點上等位基因頻率的數據表明: 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異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異的反映
  3. We present two different frameworks to analyzing the high frequency time series : first, regularly spaced sampled observations, which is sampled with interval of one hour, one minute even one second ; secondly, the irregularly spaced data, such as transaction by transaction data 。 the main work and innovations of the dissertation include : 1. through empirical research of high - frequency time series of shanghai composite index, the paper researches the different statistical properties on different frequency

    高頻時間序列的分析與建模是金融計量學的一個全新研究領域。金融市場中高頻時間序列分為兩類:一類是采樣間隔相等的數據，比如一小時、十分鐘、五分鐘、甚至是以秒為單位採集的按時間先後排列的等時間間隔的數據;另一類是指對交易過程實時採集的數據，也就是每筆交易的數據（顯然是不等間隔的數據） 。

  7. All the electric safe protection devices now being used function only one time protection when the equipment is out of order, i. e., they can ' t delay the on / off of 220v. once industrial equipment, household appliances and instruments and meters have troubles in mechanism or electronic elements because of overflow, overload, overheat or short circuit and furthermore, one time overheat switch can ' t start to function, there is no second protection device that will cut off the circuit timely, accurately and quickly, to protect the electric equipment

    根據消防部門統計，我國目前電器引起火災屢見不鮮（見1999年8月31日上海文匯報第12版報導經消防部門統計，我國目前電器引發的火災，高居火災起因為第一位） ，如以相同用量相比，我國觸電導致死亡人數是發達國家幾十倍甚至上百倍，而且這類事故的發生很大程度是與劣質電器元件有關。
