Essay Questions

81.Define supply chain and list the activities that are involved.

A supply chain is the flow of materials, information, money, and services from raw material

suppliers through factories and warehouses to the end customers. A supply chain also

includes the organizations and processes that create and deliver products, information, and

services to the end customers. The term supply chain comes from the concept of how the

partnering organizations are linked together.

A supply chain involves activities that take place during the entire product life cycle, from

dirt to dust. However, a supply chain is more than that, because it also includes the

movement of information and money and the procedures that support the movement of a

product or a service. Finally, the organizations and individuals involved are considered part

of the supply chain as well. When looked at very broadly, the supply chain actually ends

when the product reaches its after-use disposal.

Difficulty: Easy Page Reference: 307

82.List and briefly discuss the three major parts of a supply chain and the major concerns of

each part.

Upstream supply chain. The upstream part of the supply chain includes the activities of a

company with its suppliers, which can be manufacturers, assemblers, or both, or service

providers, and their connections with their suppliers or second-tier suppliers. In the upstream supply chain, the major activity is procurement. Procurement is the process made up of the activities by which an organization obtains or gains access to the resources they need for

their core business activities.

Internal supply chain. The internal part of the supply chain includes all of the in-house

processes used in transforming the inputs received from the suppliers into the organization’s outputs. It extends from the time the inputs enter an organization to the time that the products go to distribution outside of the organization. In this part of the supply chain, the major

concerns are production management, manufacturing, and inventory control.

Downstream supply chain. The downstream part of the supply chain includes all the

activities involved in delivering the products to the final customers. In the downstream

supply chain, attention is directed at distribution, warehousing, transportation, and after-sale service.

Difficulty: Medium Page Reference: 308 83.Identify three factors or capabilities that the success of an e-supply chain depends on.

The success of an e-supply chain depends on the following:

?The ability of all supply chain partners to view partner collaboration as a strategic asset.

? A well-defined supply chain strategy.

?Information visibility along the entire supply chain.

?Speed, cost, quality, and customer service.

?Integrating the supply chain more tightly.

Extranets. Their major purpose is to support interorganizational communication and

collaboration.

Intranets. These are the corporate internal networks for communication and collaboration.

Corporate portals. These provide a gateway for external and internal collaboration,

communication, and information search.

Workflow systems and tools. These are systems that manage the flow of information in

organizations.

Groupware and other collaborative tools. A large number of tools facilitate collaboration and communication between two parties and among members of small as well as large groups.

Various tools, some of which are collectively known as groupware, enable such

collaboration,

Difficulty: Hard Page Reference: 311 85.List and briefly explain the three major categories of Workflow applications.

The three major categories of Workflow applications are collaborative, production, and

administrative workflow.

Collaborative workflow. Collaborative workflow refers to those software products that

address project-oriented and collaborative types of processes. They are administered

centrally yet are capable of being accessed and used by workers from different departments or physical locations. The focus of collaborative workflow is on allowing workers to

communicate, negotiate, and collaborate within a unified environment.

Production workflow. Production workflow tools address mission-critical, transaction-

oriented, high-volume processes. They are generally highly structured applications, clerical in nature, and often include document imaging and storage. The goal is to improve

productivity and the quality of business processes.

Administrative workflow. Administrative workflow deals with administrative tasks such as routing and approval functions for such things as travel requests, purchase orders, and leave requests. Some of these applications extend enterprise wide, such as recruitment,

procurement, and expense reporting.

Windows_Server_2008_文件服务器资源管理器(FSRM)

Windows Server 2008 文件服务器资源管理器（FSRM） 数据可能以静态文件的形式存在，例如办公文档、图像信息以及电子表格等；也可能以数据库、事件日志、音频、视频数据流等形式存在。在这些情况下，信息都是作为文件集的形式存在并且允许管理。随着时间的推移，存储和维护的数据越来越多，查找和访问数据困难越来越大，文件集中管理的需求越来越迫切。 Windows Server 2008的文件服务是Windows管理体系架构中重要的组成部分，在功能上有了本质的提升，同时在保证文件安全方面也有了质的飞跃。Windows Server 2008的文件服务包括分布式文件系统（DFS）、磁盘配额、文件屏蔽等几个部分。 安装文件服务 在安装Windows Server 2008时，文件服务没有作为必选组件安装，需要网络管理员根据实际情况定制安装。 启动服务器管理器后，选择“角色”功能选项，单击“添加角色”超链接，启动“添加角色”向导，在“选择服务器角色”对话框的“角色”列表中选择“文件服务”，如图1所示。 根据向导提示继续安装文件服务，在“选择角色服务”对话框的“角色服务”列表中，选择需要安装的服务。Windows Server 2008中，将文件服务器、分布式文件系统、文件服务器资源管理器、网络文件系统服务以及Windows搜索服务集成在一起，这些服务均属于文件系统中的一部分。 根据选择的角色服务，启动不同的安装步骤，直至文件服务安装完成。 分布式文件系统

分布式文件系统（DFS）作为一种服务，使得网管员可以把局域网中不同服务器上的共享文件夹组织在一起，构建成一个目录逻辑树。用户不必知道这些共享文件夹到底在哪台服务器上，也不必一一搜索并映射他们，只需访问共享的DFS根目录，就能够很轻松地访问分布在网络上的文件或文件夹。 分布式文件系统将许多不同的逻辑磁盘分区或者卷标组合在一起形成完整的层次文件系统，为实际分布在网络上的资源提供了一个逻辑上的树型文件系统结构，从而为用户提供了访问网络上共享文件夹的简便途径。最主要的是，网络内的所有用户只要记住一个逻辑名称即可。 分布式文件系统有两种方式：一种是独立的根目录分布式文件系统，另一种是域分布式文件系统。 独立的根目录分布式文件系统，目录配置信息存储在本地主服务器上，访问根或链接的路径以主服务器名称开始，独立的根目录只有一个根目标，没有根级别的容错。因此，当根目标不可用时，整个DFS 名称空间都不可访问。 域分布式文件系统中，DFS拓扑信息被存储在活动目录中，因为该信息对域中多个域控制器都可用，所以该DFS为域中的所有分布式文件系统都提供了容错，其拓扑结构如图２所示。 磁盘配额 磁盘配额是一种基于用户和分区的文件存储管理。通过磁盘配额管理，网管员可以对本地用户或登录到本地电脑中的远程用户能够使用的磁盘空间进行合理分配，每一个用户只能使用网管员分配的磁盘空间。 磁盘配额对每一个用户都是透明的，当用户查询可以使用的磁盘空间时，系统只将配额允许的空间报告给用户，超过配额限制时，系统会提示磁盘空间已满。

水力学06,07.08年试卷及答案

2007年 一 ，名词解释： 1．连续介质：流体质点完全充满所占空间，没有间隙存在，其物理性质和运动要素都是连续分布的介质。 2．流线： 某一确定时刻t ，在流场中一定有这样的曲线存在，使得曲线上各点处的流体质点的流速都在切 线方向，这样的曲线就叫做该时刻t 的流线。 3．长管：在水力计算中，管道沿程阻力远远大于局部阻力，局部阻力可以忽略不计的管道。 4．水跃：明渠水流从急流过渡到缓流状态时，会产生一种水面突然跃起的特殊局部水里现象，既在较短的 渠段内水深从小于临界水深急剧地跃到大于临界水深的现象。 5。渗流模型： 在保持渗流区原有边界条件和渗透流量不变的条件下，把渗流看成是由液体质点充满全部 渗流区的连续总流流动。 二，解答题 1. 温度对流体粘性系数有何影响原因何在 答：温度升高时液体的粘滞系数降低，流动性增加，气体则相反，粘滞系数增大。这是因为液体的粘性主要由分子间的内聚力造成的。温度升高时，分子间的内聚力减小，粘滞系数就要降低。造成气体粘性的主要原因则是气体内部分子的运动，它使得速度不同的相邻气体层之间发生质量和动量的变换。当温度升高时，气体分子运动的速度加大，速度不同的相邻气体层之间的质量交换随之加剧，所以，气体的粘性将增大。 2. 写出总流伯努利方程，解释各项及方程的物理意义。 答：总流伯努利方程为：l h g V P Z g V P Z ++ + =+ + 222 222 22 111 1 αγ αγ 其中：Z 表示总流过流断面上某点（所取计算点）单位重量流体的平均位置势能 γ P 表示总流过流断面上某点（所取计算点）单位重量流体的平均压强势能。 g V 22 α 表示总流过流断面上某点（所取计算点）单位重量流体的平均动能。 l h 表示总流过流断面上某点（所取计算点）单位重量流体的平均机械能损失，称为总流水头损 失 γP Z H P + = 代表总流过流断面上单位重量流体的平均势能 g V P Z H 22 αγ + + = 代表总流过流断面上单位重量流体的平均机械能 3. 长度比尺为40的传播模型实验，测得船速为1.2m/s 时模型受到的波浪阻力为，试求原型船速和原型 船舶所受到的波浪阻力（以重力作用为主） 答：根据牛顿一般相似原理：力的比例尺：2222 p p p p F m m m m F l v F l v ρλρ== 弗罗特数法则 22 p m r p m v v F gL gL ==

安装好server 2003之后，我们通常通过在文件夹上点击右键共享文件夹，然后配置共享权限和NTFS权限的方式可以实现文件服务器的基本功能。升级到 Server2008之后，我依然可以通过这种方式来实现简单的文件服务器功能，另外我们还可以通过安装文件服务器角色，来配置很多高级的功能。 下面是我安装配置一个简单的文件服务器，并利用“共享和存储管理”来设置文件服务器的过程。 实验说明： 文件服务器名字：fs01 客户端：win7 两个机器在同网段。 实验环境：VMware Workstation 实验目的：安装文件服务器角色，通过“共享和存储管理”功能，配置一个share共享文件夹，对所有用户共享，但是只有只读的权限，不能改写。用于放置公司的常用表格和共享的工具软件。 1、通过服务器管理器安装添加角色 2、下一步? 3、勾选“文件服务器” 4、 5、下一步 6、勾选“文件服务器”和“windows Search服务” 7、可以勾选需要索引的卷 8、确认安装项目，进行安装 9、安装 10、安装成功，关闭对话框。 11、在“服务器管理器”中，展开“角色”-----“文件服务”-----“共享和存储管理”。在管理工具里面也可以找到。 12、点击右侧的“设置共享” 13、浏览需要共享的文件夹 14、我们选择C盘的share文件夹 15、点击下一步 16、我们来更改，编辑NTFS权限 17、给予user组可读的权限 18、下一步 19、勾选“SMB”,确定共享名。下一步。 20、点击高级，可以配置一些高级选项。 21、在用户限制标签，可以限制同时连接这个共享的用户数，或者启用禁用，基于访问权限的枚举。 22、在“缓存”标签，可以设置这个共享文件夹是否可以在客户端缓存。 23、根据自己需要设置好之后，下一步 24、这个共享文件夹，我们让所有用户都只具有只读的共享访问权限。 25、由于我们还没有配置DFS,我们暂时不要将它发布到DFS命名空间

2008年国家公务员考试试题及答案

2008年国家公务员考试行政能力测验试题和答案详解 第一部分言语理解与表达 （共40题，参考时限30分钟） 本部分中每道题包含一段话或一个句子，后面是一个不完整的陈述，要求你从四个选项中选出一个来完成陈述。注意：答案可能是完成对所给文字主要意思的提要，也可能是满足陈述中其他方面的要求，你的选项应与所提要求最相符合。 请开始答题： 1.在古典传统里，和谐的反面是千篇一律。“君子和而不同，小人同而不和”，所以和谐的一个条件是对于多样性的认同。中国人甚至在孔子之前就有了对于和谐的经典认识与体现。中国古代的音乐艺术很发达，特别是一些中国乐器，像钟、磬、瑟等各种完全不同的乐器按照一定的韵律奏出动听的音乐，但如果只有一种乐器就会非常单调。 对这段文字概括最准确的是： A．和谐观念源于中国古代音乐B．差异是和谐的一个必要条件 C．中国人很早就产生了和谐观念D．音乐是对和谐的经典认识与体现 2．“黑马”一词其实是从英语舶来的，原指体育界一鸣惊人的后起之秀，后指实力难测的竞争者或在某一领域独树一帜的人，无贬义或政治含义。首先在英文中使用“黑马”的人，是英国前首相狄斯累利，他在一本小说中这样描写赛马的场面：“两匹公认拔尖的赛马竟然落后了，一匹…黑马?，以压倒性优势飞奔。后台上的观众惊呼：…黑马！黑马！?”从此，“黑马”便成了一个有特殊意义的名词。 这段文字的主要意思是： A．论证“黑马”词义的起源B．阐释“黑马”一词的内涵 C．分析“黑马”的词义演变D．介绍“黑马”的感情色彩 3．中国的沙漠为科学家提供了与火星环境最为相似的实验室。科学家们已经去过地球上最为寒冷的南极洲，也去过地球上最为干燥的智利阿塔卡马沙漠，但他们真正需要的是将这两者结合起来的极端环境。科学家们相信，假如生命能够在地球上这些最极端的环境中生存，那么人们也有理由期待在外星球上发现生物。 这段文字意在说明： A．中国沙漠为外星研究提供了理想的场所 B．中国沙漠比南极洲更适合进行生物研究 C．科学家为何选择中国沙漠作为研究对象 D．具有最极端的环境是中国沙漠的主要特点 4．中国古人将阴历月的大月定为30天，小月定为29天，一年有12个月，即354天，比阳历年少了11天多。怎么办呢？在19个阴历年里加7个闰月，就和19个阳历年的长度几乎相等。这个周期的发明巧妙地解决了阴阳历调和的难题，比希腊人梅冬的发明早了160年。 这段文字主要阐明的是： A．中国古代阴历年中闰月设定的规律与作用 B．中国古代的历法在当时具有世界先进水平 C．阴阳历调和问题在古代是一个世界性难题 08 国家公务员考试第2 页共25 页 D．中国古人如何解决调和阴阳历差异的问题 5．湿地指的是陆地和水体之间的过渡带，和森林、海洋一并称地球三大生态体系，在维护生物多样性、调节气候、抵御洪水等方面起着重要作用。1998年那次长江大洪水让人们终于意识到湿地（尤其是和长江相通的许许多多湖泊和沼泽地）能够对洪水起到缓冲的作用。可是，许多湖泊因为围湖造田的需要而被人为隔离了，只留下一个很少开启的水闸和长江相通。

实验2-1 Windows Server 2008 文件服务器资源管理器（FSRM） 数据可能以静态文件的形式存在，例如办公文档、图像信息以及电子表格等；也可能以数据库、事件日志、音频、视频数据流等形式存在。在这些情况下，信息都是作为文件集的形式存在并且允许管理。随着时间的推移，存储和维护的数据越来越多，查找和访问数据困难越来越大，文件集中管理的需求越来越迫切。 Windows Server 2008的文件服务是Windows管理体系架构中重要的组成部分，在功能上有了本质的提升，同时在保证文件安全方面也有了质的飞跃。Windows Server 2008的文件服务包括分布式文件系统（DFS）、磁盘配额、文件屏蔽等几个部分。 安装文件服务 在安装Windows Server 2008时，文件服务没有作为必选组件安装，需要网络管理员根据实际情况定制安装。 启动服务器管理器后，选择“角色”功能选项，单击“添加角色”超链接，启动“添加角色”向导，在“选择服务器角色”对话框的“角色”列表中选择“文件服务”，如图1所示。 根据向导提示继续安装文件服务，在“选择角色服务”对话框的“角色服务”列表中，选择需要安装的服务。Windows Server 2008中，将文件服务器、分布式文件系统、文件服务器资源管理器、网络文件系统服务以及Windows搜索服务集成在一起，这些服务均属于文件系统中的一部分。 根据选择的角色服务，启动不同的安装步骤，直至文件服务安装完成。 分布式文件系统

分布式文件系统（DFS）作为一种服务，使得网管员可以把局域网中不同服务器上的共享文件夹组织在一起，构建成一个目录逻辑树。用户不必知道这些共享文件夹到底在哪台服务器上，也不必一一搜索并映射他们，只需访问共享的DFS根目录，就能够很轻松地访问分布在网络上的文件或文件夹。 分布式文件系统将许多不同的逻辑磁盘分区或者卷标组合在一起形成完整的层次文件系统，为实际分布在网络上的资源提供了一个逻辑上的树型文件系统结构，从而为用户提供了访问网络上共享文件夹的简便途径。最主要的是，网络内的所有用户只要记住一个逻辑名称即可。 分布式文件系统有两种方式：一种是独立的根目录分布式文件系统，另一种是域分布式文件系统。 独立的根目录分布式文件系统，目录配置信息存储在本地主服务器上，访问根或链接的路径以主服务器名称开始，独立的根目录只有一个根目标，没有根级别的容错。因此，当根目标不可用时，整个DFS 名称空间都不可访问。 域分布式文件系统中，DFS拓扑信息被存储在活动目录中，因为该信息对域中多个域控制器都可用，所以该DFS为域中的所有分布式文件系统都提供了容错，其拓扑结构如图２所示。 磁盘配额 磁盘配额是一种基于用户和分区的文件存储管理。通过磁盘配额管理，网管员可以对本地用户或登录到本地电脑中的远程用户能够使用的磁盘空间进行合理分配，每一个用户只能使用网管员分配的磁盘空间。 磁盘配额对每一个用户都是透明的，当用户查询可以使用的磁盘空间时，系统只将配额允许的空间报告给用户，超过配额限制时，系统会提示磁盘空间已满。
