1、浅谈计算机信息技术的广泛应用Introduction to computer information technology is widely used摘要：Pick to: 关键词：Key words: 计算机信息技术在现代社会的得到了广泛应用,与计算机信息技术相关的现代技术和产品几乎无处不在。计算机信息产业，其技术早已广泛而深入地渗透到包括生产制造、产品设计、教育科研、商业、电力等各行各业的各方面。Computer information technology in the widely application of modern society, modern technology an

2、d products related to computer information technology almost everywhere. Computer information industry, the technology already widely and deeply infiltrated including manufacturing, product design, education, scientific research, business, electric power and so on various aspects of all walks of lif

3、e. 1.计算机辅助设计与辅助制造(CADCAM)1. Computer aided design and manufacturing (CAD/CAM) 计算机辅助设计(CAD)和计算机辅助制造(CAM)主要服务于机械、建筑等产品的总体设计、造型设计、结构设计、运动机构模拟设计、有限元分析处理、工艺过程设计、数控加工和控制等环节。应用CADCAM技术，可以缩短产品开发周期、提高设计质量，增加产品种类、增强产品在市场中的应变能力和竞争能力。Computer aided design (CAD) and computer-aided manufacturing (CAM), services m

4、ainly in machinery, construction products such as general design, shape design, structure design, mechanism simulation, finite element analysis, process design, numerical control processing and control. Application of CAD/CAM technology, can shorten product development cycle, improve design quality,

5、 increase product variety, enhanced products in the market strain ability and competition ability. 2.计算机辅助教学与计算机管理教学(CAICMI)2. The computer aided teaching and computer management of instruction (CAI/CMI) 计算机辅助教学(CAI)和计算机管理教学(CMI)是计算机在教育领域的应用也是一种新兴的教育技术。在世界很多国家得到越来越广泛的应用。Computer assisted instruction

6、 (CAI) and computer managed instruction (CMI) is the application of computers in education field. Also is a kind of new education technology. In many countries around the world get more and more widely used. 计算机可以模拟自然界各种变化的现象，它用屏幕作为直观的教具，显示的图像具有直观性、动感强、速度快、色彩丰富,还可以配有音响效果。使某些以往只能用语言来间接描述的微观的、宏观的、瞬时的现

7、象得到准确、直观的表达。Computer can be used to simulate the phenomena of nature changes, it use the screen as intuitive teaching AIDS, display image intuitive, move feeling is strong, the speed is quick, the color is rich, can also be equipped with a sound effect. Make some in the past can only use indirect la

8、nguage to describe the microscopic, macroscopic, the phenomenon of instantaneous get accurate and intuitive expression. 利用CAI，计算机不仅可以向人们传授知识、提供资料，还可以帮助学生做练习、复习、解题、辅导和测验等。Use of CAI, the computer can not only impart knowledge, providing information to people, can also help students to do exercises, r

9、eview, problem solving, tutoring and test, etc. CAI与传统教学方式相比较，最突出的特点是真正实现了以学生为中心的人格化教学方法，学生可以按照自己的实际情况来选择学习内容，控制学习过程，及时了解自己的学习效果。同时，由于计算机在教学过程中表现出的无比“耐心”，所提供的安祥和谐的学习气氛，使学生完全可以消除畏惧心理，从而使学习的成功性大大提高。CAI compared with the traditional teaching way, the most outstanding characteristic is truly realized th

10、e personification of the student-centered teaching methods, students can according to own actual situation to choose the learning content, control learning process, timely understanding of their learning effect. At the same time, because the computer in the teaching process of clinking "patienc

11、e", provided a peaceful and harmonious learning atmosphere, so that the students can completely eliminate fear, which greatly improve the study the success of the property. CMI用计算机实现各种教学管理，例如教务管理、教学计划制订、课程安排、计算机题库与计算机评分等，使教学管理更加规范、高效。CMI with computer to realize all kinds of teaching management

12、, such as educational administration, teaching plan, course arrangement, computer-based computer grading, etc., to make teaching management more standardized and efficient. 3.电子商务3. The electronic commerce 借助于电子技术和网络技术来解决商贸业务过程中的各类单证交换和数据处理是人类多年的梦想。20世纪90年代以来，由于计算机技术、网络通讯技术以及单证数据交换技术的出现为人们实现这一梦想提供了可

13、能。于是自90年代中期，各式各样的电子商贸系统风靡全球，成为国际学术界、高新技术界和工商管理界研究和开发的热点。With the aid of electronic technology and network technology to solve business operations in the process of exchange of all kinds of documents and data processing is the human dream for many years. Since the 1990 s, due to the computer technolo

14、gy, network communication technology and the emergence of documents data exchange technology provides a possible for people to realize this dream. So since the mid - 90 - s, a variety of electronic commerce system is popular all over the world, become the international academia, high and new technol

15、ogy and industry and commerce management research and development of hot spots. 从狭义上讲，电子商务是指在网上进行交易活动，包括通过Internet买卖产品和提供服务，产品可以是实体化的，如汽车、电视机，也可以是数字化的，如新闻、录像、软件等基于知识的产品。此外，还可以提供各类服务，如安排旅游、远程教育等。In a narrow sense, e-commerce refers to the online trading activities, including through the Internet to b

16、uy and sell products and provide services, products can be materialization, such as cars, televisions, also can be digitized, such as news, video, software, etc. Based on the knowledge of products. In addition, you can also provide various services, such as arrangements for travel, remote education,

17、 etc. 事实上，电子商务并不仅仅局限于在线买卖它将从生产到消费各个方面影响商务活动的方式。除了网上购物，电子商务还大大改变了产品的定制、分配和交换的手段。而对于顾客，查找和购买产品乃至寻求服务的方式也将大为改进。总之，电子商务的革命性在于它对整个过程的影响它包括企业内部商务活动(如生产、管理、财务等)，也包括企业间的商务活动，它不仅仅是硬件和软件的结合，更是把买家、卖家、厂家和合作伙伴利用Internet技术与现有的系统结合起来进行业务活动。In fact, e-commerce is not just limited to online business. All aspects fro

18、m production to consumption it will affect business activities. In addition to online shopping, electronic commerce has greatly changed the custom product, distribution, and the means of exchange. For the customer, seeks to find and buy products and services the way also will be greatly improved. In

19、 short, the revolutionary of e-commerce is that it's impact on the entire process. It includes internal business activities (such as production, management, finance, etc.), also including the business activities between enterprises, it not only is the combination of hardware and software, is to

20、bring buyers and sellers, manufacturers and partners to use Internet technology combined with the existing system for business activities. 4. 电力系统4. The power system ? 电力系统是一个复杂的网络系统，其安全可靠运行不仅可以保障电力系统的正常运营与供应，更是全社会稳定健康发展的基础。随着我国电力信息化建设的不断推进，对于电力安全建设中的信息安全问题国家有关部门给予了高度重视。2003年，国家电网公司将国家电力信息网。随着社会的发展，
