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。

The core lessons of Learning Chinese present the language discursively, in English, topic by topic with example sentences, dialogues, conversations and narratives in romanization, interspersed with short exercises by which students can monitor their progress.

学习汉语》一书中的核心课程是在呈现汉语如何迥异於於英文、各主题附有组织的例句、情境对话、会话及叙述，并提供简短的练习让学生能观察自己的进度。

If you quit your session, all your global variables were saved by the system to a disk file.

如果你退出一次编程会话，你所有的全局变量就被系统存到磁盘上的一个文件里。

In this system, we introduces cluster architecture to provide global and scalable streaming caching proxy service mechanism; We implement streaming media transfer protocol on caching proxy end; We implement layered caching mechanism (global disk caching and memory caching) using dynamic sharing running memory buffer algorithm to support more stable and real-time parallel streams; We implement client request aggregation by means of streaming session sharing to reduce disk I/O and serve more user; We propose single streaming image to support the unify of pre-fetching streaming and caching streaming, which guarantees the proxy streaming of transparency for client; We design and implement streaming pre-fetching mechanism based on packet feedback information to reduce the number of "rebuffering" on client end; We bring forward streaming caching admission control policy fit for streaming caching proxy server to guarantee the QoS of streaming service.

该系统引入集群架构以提供全局的、可扩展的缓存代理服务机制；实现了缓存代理端的流媒体传输协议；采用动态共享运行缓冲区算法实现了分层缓存机制(全局磁盘缓存和内存缓存)以支持更多稳定、实时的并发流；利用流会话共享机制实现了客户请求聚集，从而减少磁盘I/O同时能服务更多的客户；提出了单一流映像，以支持预取流和缓存流的统一，从而保证代理端服务流对客户的完全透明；设计并实现了基于包反馈信息的流数据预取机制，从而减少了客户端的"rebuffering"次数；提出了适合于缓存代理服务器的流缓存准入控制策略，保证了流服务的QoS。

as the process of campus network informatization speeding up continuously,an increasing number of schools built their own mail system which is available to both teachers and students. in addition to smtp session layer's anti-spam measures,surfcontrol e-mail information security gateway riskfilter is on the application layer, anti-spam engine asa integrates four anti-spam technology: digital fingerprints, heuristic analysis, semantic analysis and the internet threat database. many surfcontrol content security experts from all over the world maintain and update asa databases 365 x7x24 hours continually, and also it wouldautomatically updated four times daily, providing an accurate rate of 99.2 percent or more higher andbelow 0.1 percent rate of misjudgment of the spam filtering effect.

随着校园网信息化的进程不断的加快，越来越多的学校搭建了自己的邮件系统，提供给教师或学生使用，系统除了smtp会话层的反垃圾邮件措施，surfcontrol邮件安全信息网关riskfilter在应用层上，反垃圾邮件引擎asa集成了四种反垃圾邮件技术：数字指纹、启发式分析、语义分析和internet威胁库，由surfcontrol全球众多内容安全专家，365x7x24小时不间断维护更新asa数据库，每天自动更新4次，提供准确率高于99.2%、误判率低于0.1%的垃圾邮件过滤效果。

Again, the gag serves as a way to editorialize upon the story's reality and also humorously point out the difference in perspective that two people have while participating in the same conversation.

同样，插科打诨充当方式editorialize经故事的现实，还幽默地指出，不同的角度看，两个人同时参加同一会话。

Ikeda's conversational style was direct, almost abrupt, though; he came through as slightly pushy, but that fit a journalist, and Ken had lost the impression of effeminacy.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
