Storage of electric power plays a more and more important role in modern society , such as , the center of modern machining and manufacture , the center of compution , communication services , electric vehicle , finance service , and so on . they have very strictly require with the stability and reliability of electric power system 电力的储蓄在现代社会中的作用越来越重要，特别是在许多高科技行业，如：现代加工制造中心、计算中心、通信服务中心、电动车辆、金融服务等领域，其对电力系统的稳定性和可靠性要求非常苛刻。
With the popularization in applying computer , most of universities and colleges have already set up large or middle - types of computer centers . at the same time , it is a common concerned question for the administration personnel of computer center on how to arrange teaching scientifically , make full use of the equipment as well as charge the spending time in the computer classroom efficiently 随着计算机应用的普及，各大专院校都建立了许多中、大型计算中心。与此同时，如何科学地安排学生教学上机、充分发挥设备作用以及有效地进行机房收费计时管理，成为计算中心管理人员普遍关心的问题。
The author has been concerned with the 3d model management system based on pdm in the 701 graduate school of the cssc , and learn about the enterprise . he has made an investigation and analysis on the enterprise current operation flow , administration system , current status of information technology and related software and hardware based on the knowledge learnt . the author has expatiated the necessity for information technology and administration in shipbuilding industry originating from the developing trend of information technologies 本文作者参与了中国船舶重工集团第701研究所pdm平台上的三维模型管理系统的研究，对该企业有一定的了解，并对当前生产运作流程、管理系统、信息技术应用现状、信息技术装备软件和硬件现状进行了调研分析，根据信息技术的发展的新趋势和该企业自身发展需求出发阐述了以pdm作为搭建船舶行业信息技术及管理平台的必要性和可行性分析，并在此基础上，结合该所计算中心的信息化工程在产品数据管理软件windchill下进行了该所舰船三维模型管理系统的开发。
To the open operating computer , it can calculate time and charge accurately . with present popular b / s structure programs design method , integrating dhtml project developing environment in visual basic with sql server 7 . 0 data base , the article have designed and developed a dynamic management system 文中采用当前较流行b s结构程序设计方法，运用visualbasic中的dhtml工程开发环境和sqlserver7 . 0数据库相结合，设计开发出了动态网页形式的计算中心管理系统。
Thirdly , decrease the difficulty of the character recognition through studying the method of character preprocessing ; at last , some effective methods of feature extraction , such as the one based on image transform with the invariant features which keep stable while the picture move , rotate and zoom in or out , and the other focused on the shape of character and features of direction 三、深入探讨了字符识别的预处理方法，减少字符识别时的运算量和难度。四、讨论了三种特征向量的提取方法，一种是基于平移、旋转和尺度不变性的图像变换法，一种是计算中心矩的方法，再就是强调字符形状和结构的方向特征量提取法，实验中通过最小距离法进行字符的分类识别，匹配时间少，识别率有所提高。
