扩展的

A NF2 extended data model with object—oriented features is presented, and its semantics is formally described. The data model has the following features. Its database schema has NF2 extended structures, the data values can be either atomatic or composed by'set'and'tuple'constructors with a fixed order. The'table'concept unifies classes and relations.

该模型的主要特点有：数据库模式是扩展的非一范式结构，数据值既可以是原子的，也可以通过构造符set，tuple以特定的顺序反复复合而成；用表的概念统一了类和关系；对象标识既可以由用户定义，也可以由系统定义。

Of course, this is Favicon not just is all, according to the browser different, favicon shows also distinguish somewhat: Above version is reached like FireFox and Internet Explorer (5.5 in most mainstream browser) in, favicon shows in the favorite not only, still can appear on address column at the same time, at this moment the user is OK daggle Favicon arrives with building to the desktop the quick way; of the website besides, label type browser still has many patulous functions even, if FireFox supports the Favicon of animation format even,wait.

当然，这不仅仅是Favicon的全部，根据浏览器的不同，Favicon显示也有所区别：在大多数主流浏览器如FireFox和Internet Explorer (5.5及以上版本)中，favicon不仅在收藏夹中显示，还会同时出现在地址栏上，这时用户可以拖曳favicon到桌面以建立到网站的快捷方式；除此之外，标签式浏览器甚至还有不少扩展的功能，如FireFox甚至支持动画格式的favicon等。

When transaction efficiency is low, thescope and depth of humen interaction is low too, and political, economicand cultural relations is not compact with a local geographical extentlimited in each continent. Along with the advance of transactionefficiency, mankind cooperative relations depthen and go into an eraof globalization and world economic integration.

人类发展过程是人与人之间关系在广度与深度上不断扩展的过程，交易效率比较低时，人与人交往的深度与广度都较低，政治、经济、文化联系不紧密，地理范围上只局限于各大洲与地区；随着交往效率的提高，人类的分工合作关系加深，逐渐进入到全球化时代并迈向世界经济一体化。

Therefore, to build a complete, efficient, and enlargeable eDoc exchange system is worth researching.

因此，如何构建一个功能较为全面的、高效的、可扩展的电子公文交换系统是当前需要研究的问题。

The model designs an extensible authentication to replace the way which the expositive security uses on Web-Tier and an authentication for controlling the accessing to the protect resource on EJB-Tier. The improved model uses directory server to manage the role information. It reduces the complex of application development, and increases the ability of migrate other J2EE platform.

针对以上不足，本文提出了改进的安全策略模型，在Web层设计可扩展的验证模块来代替原来声明式安全采用的验证机制；在EJB层设计验证模块用于对业务逻辑资源的访问控制；在角色信息管理方面，使用目录服务器存储用户角色，来降低系统开发复杂度，提高系统的可移植性。

The expanded nostrils end with fanlike flourishes, and the tip of the eel's lower jaw terminates with three tentacles.

这扩展的鼻孔以扇状的繁荣结束，和鳗鱼的下颌的尖端有限的有3条触须。

With the development of science and technology and persistent increasement of function system of intelligent building, it has become an important research field to build an efficient and extendable Structure Cabling System.

随着科技的进步及智能大厦功能系统的不断增加，建立一个使其高效工作的、可扩展的综合布线系统已成为当前重要的研究方向。

The module combine imaging processing software OpenCV and Adaboost face detector algorithm is used to select extended Haar characteristics,then the face detector is realized and the result is given.62 faces is undetected when detector designed for 592 individua...

利用OpenCV图像处理软件与Adaboost人脸检测算法的结合模块，选取扩展的Haar特征，实现了人脸检测并给出了检测结果。设计的检测器对592个人脸漏检62个，可达倒20帧/s左右。因此该方法具有较高的准确度和实时性。

While handling bones in {{literal|Pose Mode}} notice that they act as rigid, inextensible bodies with spherical joints at the end.

但我们在造型模式{{literal|Pose Mode}}中移动骨架时，你可以注意到它们会就像坚硬的不可扩展的躯体部分，同时在它们的尾端会有一个圆形的连接点。

In addition, we make a perturbative QED correction to the effective one gluon exchange process and expect that this QED and QCD interference effect will give us a good guide for understanding the charge symmetry breaking.

并指出由此得到的三体夸克—夸克对之间的相互作用在扩展的夸克势模型中可能是有用的。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
