数据记录中因为存在仿真波形抓取，所以等实验完成后再打印实验报告后几页。

振荡器可以分为两大类：正弦波振荡器和张弛振荡器、正弦波振荡器由放大器和RC或LC电路构成，这种振荡器的频率是可调的；正弦波振荡器也可以使用晶振构成，但是晶振的振荡频率是固定的。

弛张振荡器可以用来产生三角波、锯齿波、方波、脉冲波或指数型波形。

本实验讨论的是正弦波振荡器的设计。

运放的正弦波振荡器的工作不需要外加输入信号，这种振荡器利用了正反馈或负反馈的某些组合把运放驱动到不稳定的状态，这样输出就不断的来回翻转。

B&O BeoLab 4音响中的“高富帅”作为一个标新立异的时尚音响品牌，BO很多时候给人的感觉就是华丽的外形和高不可攀的价格，而其华丽的造型和优质的声音也一直备受众多用户青睐。

要说到丹麦的BO，绝大部分人的第一反应就是贵。

的确，作为一个标新立异的时尚音响品牌，BO很多时候给人的感觉就是华丽的外形和高不可攀的价格，就拿今天的BeoLab 4来说，作为一款品牌中入门级的电脑音响，其价格就在万元，而且选配的支架价格都在几千元，如此高的定价也注定了这是一个小众的品牌，一个属于高富帅的品牌。

如果你是一个设计控，如果你要彰显你不凡的品味和财力，那么恭喜你，BO绝对适合你。

O的故事国际设计界BangOlufsen（简称BO）是一个非常响亮的名字，在每年的国际设计年鉴和其他设计刊物上，在世界各地的设计博物馆和设计展览中，BO公司的设计都以其新颖、独特而受到人们的关注。

在中国的设计师和音响发烧友中，BO已经有了相当的认知度。

BO是丹麦一家生产家用音像及通讯设备的公司。

多年来，该公司把设计视为生命线，一方面系统地研究新产品的技术开发，另一方面瞄准国际市场上的最高层次，并致力于使技术设施适合于家庭环境，设计出了众多质量优异、造型高雅、操作方便并富于公司一贯特色的产品，达到了世界一流的水准，享誉西方各国。

BO的设计成了丹麦设计的经典和象征。

1925午11月17日，两位年轻的丹麦工程师Peter Bang和Svend Olufsen在丹麦小镇Quistrup一间小小的阁楼里合伙创立了BangOlufsen公司，设计和生产收音机，揭开了BO公司辉煌历史的序幕。

到1927年，公司已有30余名员工，生产出了当时十分先进的七灯电子管收音机，能自然而逼真地重现电台播送的音乐和其他节目，为公司带来了良好的商誉。

1928年，公司正式启用BO商标，商标的字体设计明显受到包豪斯平面设计风格的影响，颇具现代感，被一直沿用至今。

不久，该商标就与公司的著名广告语“丹麦质量的标志”一并使用，成了丹麦最有影响、最有价值的品牌之一。

图4-1 Lab4_1运行结果讨论：如输入磁盘号为C，显示的磁盘信息是整个硬盘信息，而不是C盘分区的信息。

如输入磁盘号为D，显示的磁盘信息与如输入磁盘号为C显示的磁盘信息相同。

用磁盘I/O API函数读出的磁盘信息是从硬盘的主引导区得到。

六、实验心得体会通过本次实验，我了解了磁盘的物理组织，不同磁盘不同的物理构造，如SSD和HDD，了解了其特点，以及如何通过用户态的程序直接调用磁盘I/O API函数（DeviceIoControl），使程序可以根据输入的驱动器号读取驱动器中磁盘的基本信息。

本次实验调试过程的前半段，我是使用Windows 10进行的，遇到了一些类型转化以及无输出的问题，纠结了很久没有弄出来，但是在Windows Server 2016中，没有任何问题，可以直接运行。

以后调试程序应尽量在目标机器上调试，防止出现问题。

Create a Use-Case Diagram4-1⎭ ⎭ ⎭Lab 4-1Create a Use-Case DiagramIn this lab, you will model a use-case diagram in the following two ways:⎭ An actor and all its use cases ⎭One use case and all its relationshipsYou will also attach flow of events (use-case specifications) to individual use cases and a project artifact that supports the use-case model. Attaching this documentation helps maintain traceability between the use-case model and requirements and can be directly accessed from the Rational Rose tool.Before You Begin⎭Do not begin this lab until you’ve completed the appropriate information in Module 4: The Use-Case Model in the Student Manual.Objective⎭In Lab 4-1, you ’ll do the following tasks to create the use-case diagrams and attach the supporting artifacts: 1. Add use-case diagrams to the browser. 2. Add actors and use cases to the diagram. 3. Attach use-case flows of events. 4. Attach a project artifact.Fundamentals of Rational Rose Student Workbook4-2Lab Outcome⎭Two completed use-case diagrams showing different aspects of the use-case model and important artifacts attached that support the use-case modelLab Artifacts⎭ Use-Case Diagram (Global View) ⎭ Supporting artifacts (text files) ⎭ Lab4_1.mdl file ⎭Lab4_2.mdl fileFundamentals of Rational Rose Student Workbook Use-Case Diagram (Global View)4-3Fundamentals of Rational Rose Student Workbook4-4Task 1: Add the Use-Case Diagrams to the BrowserWe are using a modified Rational Unified Process framework and have already added our actors and use cases under the Actors and Use Cases packages respectively. Work from the diagram on the previous page.Steps Comments1.Open Lab4_1.mdl. In the browser,expand the Use Case View and then expand the Use-Case Model package. Take a moment to look at the actors under the Actors package and the use cases under the Use Cases package.2. Create two new use-case diagrams underthe Use-Case model package in thebrowser, and name one Realtor View and the other Maintain Personal Planner View .We are creating a use-case diagram that shows a single actor and all its use cases (Realtor actor) and another that shows a single use case and all its relationships(Maintain Personal Planner use case).See the figure below.3. Continue to Task 2 on the next page to add actors and use cases to the use-case diagrams.Fundamentals of Rational Rose Student Workbook4-5Task 2: Add the Actors and Use Cases to DiagramSteps Comments 1. Double-click the Realtor View use-casediagram icon in your browser.The diagram window isopened.2. Using the diagram on page 4-3 or the global use-case diagram in your existing model, determine the use cases associated with the Realtor actor. You may have to expand somepackages to find the actors and use cases that you need.3. Drag the Realtor actor and its use casesfrom the browser into the diagram window. Arrange the diagram accordingly.Notice that the association relationships are also added automatically. We already added these relationships when we created the global use-case diagram.4.
