Chapter one analyzes the characteristics of the lnternet infrastmcture from the technical view as weii as the economic view . on the basis of the anaiysis , this chapter expounds the innuence of these features on the lnternet infrastructure itself and the whoie economy . at last , i discuss the possible problems and corresponding settlements during the providing and the use of the lnternet infrastrocture 本章首先分别从技术和经济两个不同的角度对internet基础设施进行分析，同时系统地阐述了这些特征对internet基础设施自身和外部经济所产生的种种影响，其次提出了目前在提供和使用internet基础设施过程中所遇到的各种问题以及解决思路。
The article has explained the difficult point of the state business banks of our country carrying on shareholding system transformation . then pointed out that the mode of shareholding system transformation is a financial holding company , and it has introduced the modes of foreign financial holding companies systematically at the same time . it analyzes and probes into the policy , the mode and the corresponding reform of shareholding system transformation 文章阐述了我国国有商业银行进行股份制改造的难点，进而指出股份制改造的模式是金融控股公司，同时系统地介绍了国外金融控股公司模式，并深入地剖析和探讨了我国国有商业银行进行股份制改造的方针、模式及相应的配套改革，并在最后提出了一些相关建议，希望能对我国国有商业银行股份制改造提供一定的参考价值。
Base on the research metioned above , this paper has put forward a solution for java - based web e - mail system with high security , of which the innovation points include : in the aspect of system structure , the system has adopted mvc pattern two , then adds a permanent level on this basis , which brings the 4 - levels structure : denotation level , logic level , operation level , permanent level to be ture , and improved the maintainability of the system . at the mean time , the basic classes of every level are encapsulated , which increases the expansibility of the system ; on the aspect of the security of e - mail , the system adopts double - encryption technology : the first layer adopts des encryption technology , which makes mail safely transmit in the network ; the second layer adopts shift - encryption technology , with which users can encrypt mail on the web interface . this is much more convenient and secure than before ; as to filtering garbage e - mails , the system adopts the double - filtration technology , it adopts content - based filtration in the mail server , carries on the filtration of the ip address and e - mail address at the console by looking over the log files in the e - mail server , while using regular expression to process the filtration of the html 针对以上研究,本文对基于java的安全web电子邮件系统的设计,提出了自己的解决方案,该方案具有以下的创新点:在系统架构方面,系统采用了mvc模式2的解决方案,在此基础上增加了持久层,实现了由表示层、逻辑层、业务层到持久层的四层架构,提高了系统的可维护性,同时系统还对每个层次的基本类做了一定程度的封装,提高了系统的可扩展性;在邮件私密性方面,系统采用了双重加密技术,第一层采用des加密技术,对邮件正文进行加密,使得邮件能够在网络上安全的传输。第二层使用移位加密,对des加密后的密文再进行一次加密,这样不仅方便了用户,使之在web界面上就可以进行加密,而且更进一步提高了系统的安全性;在垃圾邮件过滤方面,系统采用了双重过滤技术,在邮件服务器中采用基于内容的过滤方式,通过对邮件服务器中日志文件的查看,在控制台中进行ip地址以及邮件地址的过滤。
The management station controls systems and facilities in the local stations such as the remote control for the room accessing in the local department . it is also installed in the administrative department and executive office in the bureau for easy management . the system enhances the related management capability in the bureau and administrative departments and ensures the roles and responsibilities between the bureau and the local departments 系统在天山路社保局和临江花园社保局机房分别安装本地站，对本机房内的设备和环境进行集中的监视和管理，同时系统在两机房内分别安装管理站实现两机房的交叉管理，同时在机房管理处和领导办公室分别安装管理站实现对机房的集中管理，在机房管理处实现所有的管理工作，例如对机房门禁的远程控制授权等。
