This thesis deeply researches the J2EE security strategy on the application tier of enterprise system. The security strategy predigests the information security model and meets the security requirements expediently. But there are some disadvantages when the security requirements become more complex. The expositive security on the Web-Tier can not offer more information for authentication; there is no authentication for EJB-Tier to use, make the EJB-Tier depend on the Web-Tier; J2EE uses database or application server to manage the role information. Use database to manage the role information will increase the complex of enterprise application, and the way of application server will reduce the ability of migrate other J2EE platform. To solve these problems, the thesis designs an improved security strategy model.

本文从企业级系统应用层安全的角度出发，深入研究J2EE多层体系结构的安全策略模型。J2EE提供的安全策略简化了系统的信息安全模型，能够很方便地满足基于J2EE的分布式应用系统的安全需求，但是在面对更加复杂的安全需求时，J2EE安全策略在验证授权和角色管理中还存在不足之处：其在Web层的声明式验证机制无法为用户提供更多验证信息，可扩展性较差；在EJB层缺少业务逻辑层可供采用的验证机制，而是借助于Web层的验证机制，其耦合程度较高有悖于业务逻辑分离于表现逻辑的原则；在角色管理方面，J2EE采用数据库或者应用服务器来管理角色信息，其中，数据库管理角色的方式增加了应用开发的复杂度，应用服务器管理角色降低了系统的可移植性，两者都具有片面性。

It is featured by fractural faults,severe multiple and igneous rocks,thus the technology of fine structural interpretation plays key role in progressive development of little fault block oilfield.

The third part elaborated the Dong Fang shuo story main characteristic: 1st, the Dong Fang shuo story evolution path from simply to complex again tends to quietly, the character image from to is really unreal. 2nd, the story both carries on the history and to have violates, creates the character image intrinsic contradictory. 3rd, and Martial emperor of Han dynasty's subtle relationship is complex. 4th, the real Dong Fang shuo compares with the history in, in novel image although all-resourceful, slightly reveals actually frailly, insufficiently is plentiful.

第三部分论述了东方朔故事的主要特点：1、东方朔故事演变轨迹由简单到复杂再趋向于沉寂，人物形象由真实到虚幻。2、故事既承袭历史又有所违背，造成人物形象的内在矛盾性。3、与汉武帝的关系微妙复杂。4、与历史中真实的东方朔相比，小说中的形象虽然神通广大，却略显单薄，不够丰满。

A new gene structure is proposed: head+body+tail, which allows the program with necessary complexity and putting some learning mechanism into the search process.② A new homeotic gene structure is proposed, it not only can call for subroutines easily, but also can automatically perform programming.③ The concept of different homeotic gene, a multi-cellular structure is proposed. It can be used to describe the complex multi-level programs and to implement the complex subroutine calls.④ An estimation of distribution operator for guiding search is proposed. It fuses statistic learning mechanism into the search process to accelerate the convergent process and improve the quality of solutions.

Because the medical corporations faces a complexity market, and the process of produce is also a complexity system, you must face a lot of puzzle and problem in the process of information, such as inconstant requirement of the customers, quick movement of the market, variety breed and changeable process, incontrollable term of delivery and quality of goods, illogicality of the ability of the software and the excessive expectation of the user. J2EE (Java2 Enterprise Edition) standard, founded by Sun Microsystems in 1999, contains a whole suit of standard and criterion for enterprise level applications. It has many advantages, such as independence of platform, easy expansibility and good security, which makes it very popular in IT industry.
