近年來，隨著火車的提速造成的穩定和安全問題，軌道逐步轉為採用無縫焊接鋼軌，隨著鋼軌溫度的變化，無縫鋼軌可能會因為熱脹或冷縮的金屬特性並且在扣件阻力小而且路基較差的路段釋放能量，可能會發生鋼軌嚴重變形，更甚者會發生脹軌跑道等嚴重鐵道事故，為了避免發生如此事故，有必要定期對鋼軌的溫度應力進行檢測。In order to find an explanation and to determine the possible mechanism of these biological effects, many in vitro and in vivo studies of emf effects have been published. these studies were involved in many enzymes ( such as odc, succinate dehydrogenase, pkc ), pro - oncogene ( c - myc, c - fos, etc. ), gap junction and protein synthesis, and so on
為了揭示工頻磁場生物效應的機制，尤其是與腫瘤發生發展的關系，人們開展了較為廣泛的體內及體外的實驗研究，涉及到各種生物酶類（ odc 、琥珀酸脫氫酶、 pkc等） 、原癌基因（ c - myc 、 c - fos等） 、細胞間縫隙連接及蛋白合成等方面。Based on the new formed joint model, a variety of influential factors on first limitation load of load - transfer condition and correlated deflection are discussed. the result shows that the influence on deflection caused by void is noticeable. then, a model and a method for void detection, which use first limitation load of load - transfer condition and correlated deflection - not single deflection - as their criteria, are proposed
本文以新建立的接縫力學模型為基礎，通過對第一傳荷狀態臨界荷載及其對應彎沉影響因素的分析指出，脫空對彎沉的影響是顯著的，進而提出了以第一傳荷狀態臨界荷載與對應彎沉為指標的脫空評定模型與評定方法，使評定工作在單板系統基礎上進行，排除了接縫傳荷狀況不確定的影響。To pick up the convergence speed of traditional genetic algorithm, a modified genetic algorithm is presented, which is based on subsection integer coding, combining stable - state selection strategy with inequality individual and scaling, adaptive recombination according to gene sufficiency, self - adaptive variable step and multi - gene mutation
將兩幅圖象重疊區域的歸一化差圖象作為搜索空間，定義一個與圖象高相等維數的向量作為染色體，染色體的基因表示每一行圖象中的最優拼接點，採用常用的最小值搜索適應度函數作為視差圖像拼縫搜索的適應度函數。In the process of building and using the mass concrete structures, because of the effect of out - side condition and themselves, some faults will form in the structure, these faults will effect the bearing capability and endurance using nondestructive testing method to test the concrete ' s quality and diagnose its healthy, which has the significant sense in assessing the safety stability and research of the administering diseases this dissertation mostly researched the testing methods in the mass concrete structure, discussed the principles, methods, features, sphere of application of the ultrasonic testing in the mass concrete structure with faults, used dynamic fem to simulate the testing process, discussed when the concrete structure with cracks is under the effect of the pulse, how the elastic waves propagate and what are their changing feature, researched the principles of the first - arriving waves " phase when the cracks " depths are not same, obtained the relation between the inversion point and the cracks " depth, which has the direction sense in the application of projects, the second part of this dissertation is ct, which used the ultrasonic wave running through the tested - substance to get arriving - time of the ultrasonic wave, then inverse the image this dissertation drawed one ct program which can well present the different little cells " ultrasonic wave velocity profiles of the substance, thereby to diagnose the quality of the part of the tested - substance, ct has the better using foreground.
在混凝土結構的施工及使用過程中，由於受其自身及外界各種因素的影響，常常會產生一些缺陷，對結構物的承載能力和耐久性造成嚴重影響，採用無損檢測技術進行質量檢測和健康診斷，這對混凝土結構開展安全、穩定性評估以及病害隱患治理研究具有重要意義。本論文主要針對大體積混凝土結構缺陷的檢測方法展開研究工作，重點討論了超聲波法檢測混凝土結構裂縫的基本原理和方法及其特點、適用范圍，運用動力有限元數值模擬其檢測過程，探討了有裂縫缺陷的混凝土結構在脈沖荷載作用下彈性波的傳播及其變化特徵，研究了不同裂縫深度下首波相位變化規律，得出了反轉臨界點與裂縫深度之間的關系，這對實際工程應用具有指導意義。聲波ct是一種新的無損檢測技術，它是利用聲波穿透被檢測體獲取聲波接收時間，來進行計算機反演成像的技術。This is the direct reason of bad reservoir property of sandstone, especially lower permeability. the influence and control factors of reservoirs include : deposition, diagenesis and tectogenesis. the deposition is the basic factor, it control the shape and distribution of sand body, and influence the type and the intensity of the diagenesis ; the diagenesis is the key factor, it control the process of pore evolvement, so the diagenesis control the sandstone ' s storage space and reservoir quality directly ; the fracture of the tectogenesis formation could improve the porosity and permeability of sandstone
其中沉積作用是基礎，控制了儲集砂體的形態特徵和分佈范圍，同時由於不同沉積類型砂體在碎屑成分組成、泥質含量、顆粒粒度、砂體厚度、砂體內部的非均質性、孔隙介質的物理化學性質等方面不盡相同，從而也影響著砂巖所經歷的成巖作用路徑、類型和強度，因此沉積作用是控制儲層發育的主導因素；成巖作用是關鍵，直接決定了砂巖的孔隙演化過程，從而決定了儲層內部儲集空間特徵和儲集性能；而構造作用形成的裂縫對改善砂巖的儲滲性能具有一定作用。The benchmark data for theoretical analysis are obtained by calculation results of finite element models. in order to have a sound finite element model, the plastic quadrilateral shell elements model established in 1996 by bahaari and sherbourne is improved by using solid 8 nodes elements in ansys programs
為了使理論分析有充分而且精確的基本數據，本文改進了bahaari和sherbourne提出的四邊形塑性殼單元有限元模型，建立了能夠考慮焊縫、摩擦力和預應力等因素影響的端板連接節點的三維實體單元有限元模型。分享友人
