访问对象

If an object has a property with the property name used in the property accessor then the value of that property is returned

在原型参与情况下的从对象属性读值，如果一个对象在对象属性访问链中存在就把它的值返回。

The static model describes the relationship among user, permission and role and imports integrated inheritance to actualize the relationship between local role and global role. The dynamic model completes access control by session diffluence based on the static model. The actualization for the model is researched based on the analysis of the content and the rule of the model. A self-adapted RBAC wrapper based on agent model is presented according to the heterogeneous databases'demand for wrapper.

该模型比较全面地解决异构数据库系统的局部数据对象和全局数据对象的综合访问控制。I-RBAC模型包括静态模型和动态模型两个部分，静态模型主要描述用户、权限、角色（特别是全局角色与局部角色）之间的关系，动态模型是在静态模型中角色层次关系的基础上通过会话分流实现动态的访问控制。

In the algorithm, there is no master site that objects address computations must go through or access to a centralized directory. All compute nodes and storage nodes calculate node address independently, the objects access and storage nodes change never require atomic updates to multiple clients. The compute nodes adapt to the change of storage nodes by client image adjustment algorithm.

该算法使得数据对象分配地址的计算不依赖于中央节点计算或者访问一个集中式目录，所有计算节点和存储节点独立地进行地址计算，并且对数据对象的访问操作或新增节点引起的系统规模变化不需要原子更新到其他计算节点，计算节点通过视图校正算法自主学习，自动适应新的系统规模。

It becomes more difficult to manage, integrate and share the control system real-time data when we set up the industrial real-time database because of complicated affair between every department and isomeric character of the system. A three-level-structure model and the method to establish database is provided based on CORBA criterion with its character of being regardless of programming languages, hardware platform and network protocol . A universal real-time database faces multi-system is also set up by learning the distributed criterion, it can realize the request broker , and the application software can visit the database pellucidly ; Thus the power station simulation model can be linked with the control system such as infi90 , ovation and be made use of the control object , a closed simulation and control experiment system is set up. Further more we can build an integrate automatic experiment platform from the simulation object of power plant to the process control and the to SIS.

在创建工控领域实时数据库时，企业各部门间的复杂事务及内部异构性给实时数据的管理、集成和共享带来了一定的困难，根据CORBA规范具有语言无关性、平台无关性和网络协议无关性的特点提出基于分布式计算规范CORBA的三层体系结构模型及建立与维护实时数据库的方法和途径；通过CORBA规范建立面向多个分散控制系统的通用实时数据库，实现数据访问代理，使应用软件可以透明地对实时数据库进行访问、存取、管理；将Infi90、Ovation分散控制系统与火电厂仿真机模型进行有效的互连，以全物理过程仿真数学模型为对象，构建了闭环控制仿真实验研究系统，实现数据的高效连通及管理；进而通过基于CORBA的实时数据库构建一个从火电厂仿真机对象到过程控制设备再到SIS系统的综合自动化试验平台。

The method comprises the following steps: a conversation initialization request message transmitted by a service requester is received, wherein the request message comprises an application service quality parameter and service description information; according to the application service quality parameter and the service description information, a access protocol intermediate node of the corresponding simple object and a service provider are selected; according to the intermediate node and the service provider, access protocol routing information of the corresponding simple object can be acquired; and the conversation initialization request message containing the access protocol routing information of the simple object is transmitted to the corresponding service provider.

本发明方法包括：接收服务请求方发送的会话初始化请求消息，所述会话初始化请求消息中包含应用服务质量参数以及业务描述信息；根据所述应用服务质量参数以及业务描述信息选择对应的简单对象访问协议中介节点以及服务提供方；根据所述简单对象访问协议中介节点以及服务提供方获取对应的简单对象访问协议路由信息；向对应的服务提供方发送包含所述简单对象访问协议路由信息的会话初始化请求消息。本发明还提供一种路由系统以及相关设备。

The frame adopted for this survey was the telephone listings for the Taiwan Area. In order to avoid being unable to select those residences with unlisted telephone numbers, we first took a systematic random sample of telephone numbers, and then replaced the last digit with a random number. Respondents were chosen from within the selected household according to a set intra-household sampling procedure. The target for this survey was 1200 successful interviews.

本研究以台湾地区住宅电话簿作为抽样的母体清册，为避免未在电话号码簿上登记的用户无法被抽中进行访问的情形，抽样时首先依系统抽样的原则抽出某一电话号码，再以随机乱数取代此号码的尾数，作为访问的样本户，访问时再由访员依户中抽样的原则，抽出应受访的对象进行访问。

When we develop applications, we undirectly handle database, in other words, operations of database is transparent to coder.

在实际实现时，可以直接对数据库进行操作，也可以对每张表建立一个对应的对象，这个对象封装了对数据库的访问，当我们编写应用程序的时候就可以不直接与数据库打交道，访问数据库的事对我们是透明的。

The main purpose of this research is to explore the relationship between East Seediq Tribe's folksong and life after the battle of Truku. The study time is during 1914 to 1945. In this study researcher conducted the perspectives of ethnic musicology, social musicology and qualitative research method. The findings of this research can be presented in 3 parts, the first part is the process of community transition, the second part is folksong's style, and the last part is the learning and reproduction of folksong.

本研究主要在探讨东赛德克群在太鲁阁战役后，歌谣与生活的关系，因此将研究的时间锁定在19141945年间，也就是太鲁阁战役后至光复为止，以民族音乐学、音乐社会学之观点并采用质化之研究方式，以东赛德克人为访问对象，经过搜集、分析、归纳后在研究结果的呈现上分成为三大部分，其一为社群变迁历程，其二为歌谣风格的呈现，其三为歌谣学习与生产。

After this exercise, participants rated their co-workers on such statements as:"If X promised to copy a presentation for me, s/he would follow through," and X would never intentionally misrepresent my point of view to others.

之后，研究人员要求访问对象就以下一些陈述为他们的同事打分：&如果甲答应帮我复印一份演讲，他/她就会照办，&以及甲从来不会向他人故意曲解我的观点。

In this paper a novel ontology-based data semantic fusing frame named ODSF is introduced, the basic element of ODSF is dataset its semantic is obtained by the mapping between the domain ontology and dataset. ODSF adopts nested relation model to represent the schema information of dataset, and realizes the data fusing from coarse-grained level to the small-grained level by wrapping the datasets registered in virtual database as a new dataset. We also present the semantic model of ODSF, query executing process and algorithm of virtual database, so ODSF can provide the semantic supported and QoS supported data access for user. The experiments demonstrate our work and show the feasibility and effectiveness of ODSF and its key techniques.

本文提出了基于本体的语义数据容融合方法ODSF；该方法中的基本元素是数据对象，通过数据对象和领域本体之间的映射关系来表达数据对象的语义，使用嵌套关系模型来表达数据对象的模式信息，通过一个网格节点中集成的所有数据对象作为下一个节点的数据对象来实现数据资源由粗到细的融合；定义了ODSF的语义模型，给出了虚拟数据库的查询执行过程和算法，可以为使用者提供具有语义支持、服务质量保障的数据访问服务；通过原型系统验证了ODSF中理论和关键技术的正确性和可行性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
