帮忙翻译 毕业设局域网英文摘要

以下翻译杜绝机译，请楼主放心。不过你两篇摘要，能否追加50分呢？

为了实现一个有限区域内资源的共享和加强各部门之间的联系，实现一个中小型园区局域网对于企业和用户来说都是必不可少的。企业局域网就是一个通信系统，它在一定的地理区域内，可使多个相互独立的设备在同一共享的介质上以一定的速率进行通信。每一个局域网包括一种共享介质，通常是电缆，许多计算机都连在上面。计算机按顺序使用介质来传送包，以达到传送目的，为企业提供一个良好的通信，共享环境平台。企业将建成企业网站网络中心，实现各直属主要职能部门信息上网。中心在于本企业的网站，与下属各职能部门中的各种生产、业务系统相连，而对于暂时没有条件建立自己站点的部门或二级部门则在中心服务器上提供虚拟站点，做到企业内部网络互联互通，实现办公自动化，增强各部门的协调能力。

In order to achieve the sharing of resources and the linking among various departments in a definite area,
To set up a middle or small campus LAN is necessary for enterprises and other users. Enterprise LAN is a communication system; it can realizes communications in a certain geographical area and with a given speed, which will be realized on a common shared link and several individual terminals. Each LAN will be composed with a common shared medium, usually the cable link connected with many computers. Computers utilize the medium sequentially to transmit packets so as to achieve the purpose of transmitting information, providing the enterprise with good communications and sharing the environment platform. The enterprise will become the network center of the enterprise website in which will all the information from all the functional departments will be collected. The website that the center is in this enterprise is linked with various production and business systems in the subordinate functional departments, and for the departments or second level of departments that have not condition to build up their own sites virtual sites will be provided in the central server, so that the mutual linking and connection inside of the enterprise and office automation are realized, and the coordination capability among all the departments is enhanced.

摘要：随着网络的逐步普及，医院局域网的建设是医院向信息化发展的必然选择，医院网络系统是一个非常庞大而复杂的系统，它不仅为现代化医疗、综合信息管理和办公自动化等一系列应用提供基本操作平台，而且能提供多种应用服务，使信息能及时、准确地传送给各个系统。而校园网工程建设中主要应用了网络技术中的重要分支局域网技术来建设与管理的，因此本毕业设计课题将主要以校园局域网络建设过程可能用到的各种技术及实施方案为设计方向，为医院局域网的建设提供理论依据和实践指导。
Abstract：With the increasingly popularization of Internet the construction of hospital LAN has becoming an inevitable choice for a hospital to develop towards informationization. A hospital network system is a huge and sophisticated one, it not only provide a basic operation platform for various applications such as modern medical treatment, comprehensive information management, and office automation, but also can provide various application service, so that the necessary information may be transferred to all the systems timely and exactly. As for the construction of campus network it mainly adopts LAN technology to build up and manage, which is an important branch of network technology. The topic of this graduation design is to take various technologies and implement schemes as the orientation, which will be employed in the construction process of campus network, provide theoretical basis and practice guidance for the construction of hospital LAN.
