Li Zimu,Xu Ming and Zhou Xingming（School of Computer Science,National University of Def ense Technology）Abstract: In this paper,we propose a new vers ion-control set refreshing algorithm,which adopts the mechanisms of incre mental maintenance,version control and batch processing to ensure on-line maint e nance and consistency.

本文提出了一种版本控制集合刷新算法VSRA，它采用增量维护和批处理思想，首先根据原始数据的变化集合，计算出实体化视图的刷新集合，然后据此集合刷新实体化视图，同时利用版本控制保持数据仓库与当前数据库状态的一致性，达到对数据仓库联机维护的目的。

Apart from simulating the manul design procedure, It is one of the main aim for the CARYD to realize the design result of longitude and cross-section profile in the entity way agreeing with the influence tendency for the reason that the solid entity design can not only provide the user with visual effect but also make it simple and exact to calculate the quantity of engineering work, particularly the earth-work of filling-in and digging-out.

铁路站场横纵断面计算机辅助设计软件除保证传统手工方法的实现，实体化设计的流行趋势也是论文作者追求的主要目标之一。实体化的设计结果不仅具有很高的可视性，利用该设计结果也使得填挖方工程数量的设计计算变得更方便、更准确。

The Optionality of the RelationshipHaving established the kind of the relationship between any two entities, you should now consider whether the relationship is optional for either or both participants.

当完成建立任何两实体间的关系后，你还必须确定这些关系对于参与实体的一方或双方的可选性。

In this paper,according to the characteristic of design for camera,Parametrical entity modeling,design for assembly,check-up of interference entity and method of creating 2-D drawing are introduced and means of designing this kind of products are discussed.

根据照相机工程设计的特点，介绍了SolidWorks参数化实体建模、装配体的设计、干涉实体检查以及二维工程图的产生方式，并对该类产品的设计方法进行探讨。

The use of the molecular formula for the active ingredient named in defining the required strength of a Pharmacopeial article is intended to designate the chemical entity or entities, as given in the complete chemical name of the article, having absolute (100 percent) purity.

用于表示化学实体或实体的活性成分分子式的使用，当给出物质的完整的化学名称，具有绝对（100%）的纯度。

They don't want to mix their persistence logic with their domain entities. They want to use POCO objects for their entities.

他们不想将他们的持久化逻辑与域实体混合起来，他们想为他们的实体使用POCO 对象。

User Members shall ensure that, once a preshipment inspection entity and an exporter agree on an

用户成员应保证，一旦装运前检验实体与出口商商定检验日期，装运前检验实体即应在该日期进行检验

The first member shall be chosen from section of the above list by the preshipment inspection entity concerned, provided that this member is not affiliated to that entity .

第一名成员应由有关装运前检验实体自上述名单的组中选出，只要该成员不附属于该实体。

The design pattern was given in this paper, by classifying entities and eliciting common attributes for every entity type, can be used to design the database which avoids data redundance and has great flexibility.

提出一种数据库设计模式，通过将实体归类并为不同类别的实体提取公共属性，从而使利用该模式设计的数据库在避免数据冗余的同时又具有很强的灵活性。

To enhance security in Ad-Hoc networks,it is important to evaluate the trustworthiness of other nodes without centralized authorities.In this work,authors focus on the evaluation of trust evidence in Ad Hoc networks.First,the authors introduce the metrics of the trust,the evaluation process is modeled as a path problem on a directed graph,where nodes represent entities,and edges represent trust relations.Using the theory of semirings,a trust evaluation model based on semiring（TD-SEMIRING） is developed,then two nodes can establish an indirect trust relation without previous direct interaction and introduce the application of this model in route election.At last,the feasibility of this model is analyzed.

讨论了对可信事件的评估：首先介绍了可信的相关概念和相关的特性；接着评估过程被建模成一个在有向图寻找最短路径的问题，在该有向图中结点表示实体或者用户，边表示可信关系，通过使用半环理论，建立了一个基于半环的可信性评估模型TD-SEMIRING，在两个以前没有进行相互操作的实体之间建立间接的可信关系，介绍了这个模型在路由选择当中的应用；最后，通过仿真实验，验证、分析了该模型的有效性。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
