Involuntarily, questions of these engineering datas " management appear, datas " persistance only depending relational model and rdbms is greatly insufficient, so this paper carefully studies object - relational mapping based on rdbms based on the analyse of home & overseas actualities, correlative theories and realizing methods of object - relational mapping, we find opl based on rdbms is the most suitable for object relatinoal mapping of clera. based on the engineering application analyse of opl in clera, function requirements, database modes, interface criterions and functions, running modes of opl have being detailedly described. with the framework of microsoft dna, a kind of realizing method of opl based on com / dcom / activex component technology has being brought forward, and this paper describes realizing keys from base tables " definition, object id and class hx class and inheritance of class, object storage, parallel control and affair, object query, object nesting, relations between objects, support of complex data types, right control of object and buffer management of object
本文在分析對象?關系映射技術的國內外現狀、相關理論及實現方法的基礎上，研究發現基於rdbms的opl是目前最適合clera的對象?關系映射方法；在clera的opl應用分析的基礎上，詳細描述了opl的功能要求、數據庫模式、介面規范與功能、運行方式等內容；結合microsoftdna開發框架，提出了一種基於com dcom activex組件技術的opl實現思路，並從基本表定義、對象標識與類標識、類與類繼承、對象存儲、並發控制與事務、對象查詢、對象嵌套、對象間聯系、復雜數據類型的支持、對象級權限控制及對象緩沖管理等幾方面概述了實現要點。Though much progress has been achieved in previous study, there still remains a lot to be studied and perfected. the thesis is devoted to study on the multi - ribbed slab wall, the main bearing member in mrss, including its mechanism, failure mode, aseismic capability, mechanical models, ultimate bearing capacity and aseismic design based on control. the paper mainly accomplished such work as follows : 1 ) based on test research on multi - ribbed slab wall, the paper proposed the member ' s failure modes under horizontal loads, analyzed the co - performance between the inner frame and the infilled silica bricks and that between the slab and the outer frame, discussed the wall ' s bearing capacity, rigidity, deformation, ductility and energy dissipation ability in different modes, and put forward a simplified mechanical model of the slab wall under vertical loads
本文針對密肋壁板結構的主要受力構件? ?密肋復合墻體為研究對象，就其受力機理、破壞模式、抗震性能、三階段力學模型、極限承載能力以及基於控制的抗震設計方法等進行了較為詳細的研究，完成的主要工作有： 1 ）通過對密肋復合墻體在水平低周反復荷載和單調荷載作用下的試驗研究，提出了墻體的主要破壞模式；分析了框格與內部填充砌塊、墻板與外框的共同工作的受力特點；探討了不同破壞模式情況下墻體的承載能力、剛度、變形、延性、耗能等抗震性能，並給出了豎向荷載作用下密肋復合墻體的簡化力學模型。The simulating results indicate that the scheme is stable in linear frame, and exists weak instability on the intersecting points of lateral boundary and interface in nonlinear frame. in present stage, a technique of using damping zone to limit the movement of the intersecting points is used to avoid this instability problem, however, to solve it thoroughly, the original model has to be modified in the future
實驗證明，在線性框架下該模式是穩定的，但在非線性模擬中卻出現了由邊界角點引起的弱不穩定現象，必須對模式作進一步修改，為此同時提出了以消波器消除該角點影響的限制性解決方法。In addition, the multi - level object rbac object - oriented framework has been built using the practical access control designs and experiences. the mlorbac model is mainly used in the multi - objects systems, such as the civil aviation operation system
並將權限控制方面已有的設計和實踐經驗組織成一個類體系結構，構建了一個應用於多個應用領域的mlorbac權限管理的面向對象框架。This paper explores the development of the digital forensics process, compare and contrast several forensics methodologies, and finally proposes an abstract model of the digital forensic procedure, named, requirement based computer forensics process. this model attempts to address some of the shortcomings of previous methodologies, and provides the following advantages : a consistent and standardized framework for digital forensic tool development ; a mechanism for applying the framework to future digital technologies ; and, the potential for incorporating non - digital electronic technologies within the abstraction. third, digital evidence is easy to be modified and erased
此模型提供了一個更為有效和抽象的計算機取證過程框架，它不限定哪類取證調查環境應該提供哪些取證過程，所有這些，由產品的用戶、開發人員或其它第三方在實際應用中根據實際需要來確定，這為描述不斷變化的復雜現實應用環境中的安全需求提供了靈活性，也使得研究制定統一的計算機取證過程標準成為可能，同時開放性的模型框架為將其它領域中的實用方法（如傳統取證中的方法）結合進來鋪墊了道路。分享友人
