  1. The studies of plane heterogeneity are as follows : the text counts the parameters of the sandlayers " geometric shape of different sedimentous microfacies ; speculates the conditions of lateral communication by sandstone density according to the method brought forward by j. r. l. allen ; gets a group of parameters including the reservoir thickness, porosity and coefficient of permeability by using kriging method according to the data of logging results ; makes certain the direction of coefficient of permeability with variation function by modeling globosity function ; divides the sandlayers into five types by using the method of flowing cell based on three parameters, that is x h, kxh and h / h, and accounts the favorable region. on the base of above - mentioned studies, the text evaluates the heterogeneity of sandlayers and gives the resolutions to these problems to serve the development of the field

    Allen ）等人提出的統計方法，用垂向上砂體密度的界限來推測砂體側向連通情況；根據每口井的測井解釋資料，利用克里金插值法對外間進行插值，得到了一組反映儲層特徵在平面上變化的參數，包括儲層厚度分佈、孔隙度以及滲透率，並且成圖；利用變差函數法，通過球狀函數模擬，確定儲層優勢滲透率方向：根據流動單元法，以儲能系數、容積系數以及凈毛厚度比三個參數為依據，通過聚類分析方法進行流動單元劃分，並且按照參數特徵將其分為五類，統計各砂層有利流動單元區塊。
  2. 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。
  3. According to the basic theory of iir filters, a scheme of hardware implementation is worked out combining with the fact that coefficients of numerator and denominator of transfer function are fixed and the structural feature of selected hdpld. from the clew of implementing a stratified ， modularized and parameterized design ， the thesis describes the hardware implementation of the iir filter with vhdl and schematic diagram design method. two examples that are iir notch filter and iir low - pass filter are given ， the stability of filters and the effects of quantification of coefficient are also analyzed
