針對以上存在主要問題，本文進一步提出了優化飛機融資的總體構想，包括：根據其每年的外匯流入總量及幣種構成確定國航合理的飛機境外融資規模應與負債幣種；在利率結構方面，擴大浮動利率在整個國航外債中的比重，選擇適當時機將部分固定利率貸款轉換為浮動利率貸款；在飛機引進多元化方面，通過與飛機製造廠商、出租公司飛機互換的方式優化機隊構成，結合提前中止現有飛機租賃就能夠起到優化債務結構和機隊構成的事半功倍的效果，以及在未來飛機融資中優先使用經營性租賃等。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。The polyhedrin gene sequence in recombinant virus bmpak - hbmp can be more benefit to enhancing the expression of the hbsag ( pres2 + s ) from atg initial codon at the 5 " ends of pres2 gene
另一方面， elisa檢測表明， presz抗原性提高率約是hbsag的14倍，提示bmpak hb帥中多角體基因部分堿基序列的存在更有利於從presz前的atg開始表達中蛋白全基因（ presz s ） 。Without much theoretical deduction in this dissertation, we focus mainly on the several characteristics of wavelet, such as the localization in both the spatial and the frequency domain derived from the compact support in the two domains ; the rnultiresolution representation property ; and the octave divided frequency property, etc. after a brief overview of the principles and methods of image compression, video coding algorithms are introduced including 3 - d wavelet video coding and 2 - d wavelet video coding. based on the above, the research of this dissertation consists of three aspect : firstly, the 3d - spiht algorithm is modified which optimizes bit allocation
具體說，本論文包括以下內容：首先，本文分析介紹了小波理論，文中沒有過多的理論推導，而是從小波具有的一些特性，如時頻局部性、多解析度分解特性和倍頻程頻帶分解特性入手，力求對小波變換有一個宏觀的了解。其次，介紹了基於小波的圖像編碼的原理和常用的編碼方法。最後，介紹了基於小波的視頻編碼的方法，一種是基於3 ? d小波視頻編碼，另一種是基於2 ? d的小波視頻編碼方法。In this paper, an improved genetic algorithm ( ga ) was applied to the design of high performance e - plane waveguide filters at the first time. for dealing with the shortcoming of ga as low efficiency in local optimum searching, the idea based on parallel genetic algorithm ( pga ) known as separate local optimization was presented. by separating the whole population into sub - populations, and adding a new operator known as crossover between two sub - population, the new method can provide as 2 3 times quickly as traditional ga. all numerical examinations illustrated the high convergence speed and good global searching of the new algorithm, and proved the validity of it
由於遺傳演算法表現出良好的全局搜索性能，因此本文將其應用於高性能e面波導濾波器的設計中.針對傳統遺傳演算法所存在的局部搜索能力差的缺點，本文在并行遺傳演算法的基礎上，通過將原有群體劃分為多個子群體，利用多個子群進行局部極值點的搜索，並利用群間遷徙，使改進后的演算法收斂速度平均提高了2 3倍.數值實驗表明演算法具有較快的收斂速度和較好的全局搜索性能，證明了演算法的有效性分享友人
