在指紋圖像增強方面,本文針對傳統的基於gabor濾波器指紋圖像增強演算法魯棒性差以及通常會改變奇異區紋理結構的缺點,對原有演算法進行了一些改進:首先通過檢測奇異點確定奇異區,然後根據局部區域在指紋圖像中的位置構建相應取值方式的低通濾波器並對該局部區域方向圖進行濾波,最後根據指紋圖像紋線的特點對gabor濾波器參數進行設置。Based on the fem program on fracture of plane structure developed by professor fu xiaoling of ho hai university, a two demension damage and fracture finite program package which is programed in fortran 90 language is developed. the paper adopts the plane - eight - nodes isoparameters element and compute the developing law of the damage and macro - damage of plane structure under load. considering the original damage and tension and compression damage at the same time, the paper adopts the more reasonable concrete constitute relation of two demension and exponent function model
在河海大學符曉陵副教授所編制的平面結構斷裂有限元程序( dl08p4 )基礎之上,本文用fortran90語言編制的二維損傷-斷裂有限元程序包,程序採用平面八結點等參數單元分析計算平面結構在外荷載作用下損傷及宏觀裂縫的發展規律,考慮了混凝土結構體內存在著初始損傷和同時存在的拉、壓損傷,並且採用更為合理的具有損傷含義的混凝土二維本構關系(即正交異性損傷模型中的本構方程)和指數函數模型建立的並可進行拉、壓損傷可比性換算的損傷演變方程,較為真實地反映了實際情況。It is shown by structural seismic response of four wavelets that littlewood - paley wavelet is not suitable for structural seismic response, because structural response is too small, meyer wavelet is a better wavelet for structural seismic response, for it ' s structural response is agreement with the finite element method, and also harmonic wavelet, structural response under earthquake is a little bigger than finite element method, structural response under odd exponent wavelet is also bigger than finite element method, this method is very simple by wavelet transform, wavelet transform method is different from old methods, one is with which not only knows the effects of earthquake wave detail frequency - band on structural response, but also considers earthquake wave ' s non - stationary of frequency and time - domain value, another is the second mode shape and higher mode shape response that do n ' t attenuate so fast
通過對這四種小波的結構地震反應分析研究說明: littlewood ? paley小波不適合於用來作結構地震反應分析,因為在littlewood ? paley小波下的結構地震反應太小,不符合實際情況;用meyer小波作結構地震反應分析比較合適,和有限元法的結果比較接近;也可以用諧波小波來作結構地震反應分析,只是在諧波小波下的結果略為偏大;單邊指數小波下的結構地震反應分析比有限元法稍大一點,它通過小波變換大大簡化了結構地震反應分析。用小波變換方法來進行結構地震反應分析和以往方法不同的是:它不僅可以知道地震波的具體頻率段對結構反應的影響,而且同時考慮了地震波的幅值非平穩性以及頻率非平穩性;另外與以前方法得到的結果有差異的是,第二振型及以後的高一點的振型的反應沒有以前的方法衰減得快。( s ) weathering and unloading action which are the two main exogenous process is active in epigenetic - surface. so, although one is different with the other, they are associated with each other closely and are cntrolled by geostress and seepage fields. in fact, weak weathered zone corresponds to weak load - off one, strong weathered zone corresponds to strong load - off one in virtue of result of this dissertation. ( 6 ) rock mass is a geologic body which is composed of rock and structural plane. and under the condition of geostress. temperature and seepage fields, correspondingly. studying weathering should pay attation to the aspects of rock, structural plane and fields. according to this. the author subdivises rockmass weathering into rock weathering and structural weathering, ulteriorly, the dissertation studies rockmass weathering from three aspects as follows : ? ock weathering : aberrance degree of mineral and physical mechanical performance of weathered rock ; ? e have already knew that weathering action damage the integrity of rock mass, but few applies it to engineering practice. the dissertation is based on trend o
本文研究結果為弱卸荷與弱風化大致對應、強卸荷與強風化大致對應; ( 6 )巖體是由組成它的巖石與缺陷賦存於一定環境場中的地質體,據此本文將巖體風化細劃為巖石風化與結構面風化,並進而將表徵巖體風化的指標相應地歸結為三個方面來加以研究並應用於工程實踐,這就是:對于巖石風化,主要為礦物的變異程度與風化巖石的物理力學性能研究:雖已認識到風化作用破壞了巖體完整性,但將該理論應用於巖體風化分帶卻不多見,本文即從淺表部位硬性結構面間距、條數、跡長、塊度等隨遠離臨空面的變化規律來研究巖體風化分帶:不同風化、卸荷程度的巖體實際處于不同環境場中,彈性波速變化與特定環境場相對應,因而是反映巖體風化、卸荷的綜合因素。All the contents are developed around a set of scaling laws taking the form of exponentials which relate to almost all the issues of complexity including fractals, chaos, strange attractors, localization, and symmetry breaking, etc. the main work can be summarized as follows : starting from the law of allmetric growth three fractal dimensions in a broad sense are derived, and according to these dimensions, geographical space is divided into three levels, i. e., real space, phase space, and order space, each of which corresponds to a kind of dimension. based on the idea of spatial disaggregation and using the rmi ( relationship - mapping - reversion ) principle, the urban system is formulated as three scaling laws of the three spaces, including number law, size law, and area law, which can be transformed into a set of power laws such as allometric law and zipf ’ s law associated with fractal structure

還原翻譯:系統鷹架的結構承載力因不同架設會出現一定差異,如接頭位置的改變、鷹架層數的更改和架設方式的選擇,架設方式指有無假設斜桿和幾根斜桿。Both absolute difference and relative difference among per capita gdps of 14 cities ( prefectures ) increased year by year since 1990 - the absolute difference increased linearly - - and this increased tendency would n ' t change in short period. by counting the discrete and ratio between per capita gdp of every city ( prefectures ) and that of the total province, the relative development speed of every region and the industrial structure of every region, i think that the characteristic of the spatial structure of regional economic difference in hunan is that the area along the beijing - guangzhou railway line in the east of hunan developed fast, while the vast area in the west of hunan developed slowly, so the regional difference increased constantly. on the difference background between the east and the west of hunan, there is the difference between central region and fringe region, for one thing it shows ring difference, namely chang - zhu - tan internal ring, surrounding chang - zhu - tan medium ring, the outermost external ring, the most underdeveloped counties lie on the fringe and mountain regions in the west, south and east of hunan, for another it displays that the peripheral regions of 13 prefectural cities are more developed than the other
文章還建立了反映基礎設施水平、經濟發展水平、社會發展水平的23個主要指標構成的湖南省區域差異衡量指標體系,在此基礎上,藉助spss統計分析軟體,運用主成分分析法,對湖南省14個市州經濟發展綜合水平的差異狀況進行了研究,結果表明:長沙市的經濟發展綜合水平在14個市州中遙遙領先,反映了湖南省經濟發展空間結構的「單極主導」特徵;通過計算人均gdp的標準差和標準差系數,研究區域經濟差異的總體水平及區域經濟不平衡發展的演變趨勢,發現90年代以來湖南省各市州人均gdp的絕對差異和相對差異都在逐年擴大,其中絕對差異隨年份直線上升,且這種差異擴大的趨勢在短期內難以改變;通過計算各市州人均gdp與全省人均gdp的離差和比率、各市州發展速度的差異及產業結構的差異,認為湖南省區域經濟差異的空間特徵是:湘東京廣沿線地區基礎較好,發展較快,湘西地區發展緩慢,地區差異不斷擴大;通過以縣為對象的差異研究發現在湘東湘西差異的大背景上還有核心區與邊緣區的差異,它一方面表現為長株潭內層、圍繞長株潭的中層、更遠的外層的圈層差異特徵,最落後的縣分佈於湘西、湘南、湘Structural variation index
