abstract
The graduation design is based on the Pro/e computer modeling design , one of the main part is software Pro/e application. Focus on modeling process of papers.
Due to the papers written order is: according to the actual work, from the 3d modeling software parting, again carries on the nc machining of related work. The first chapter is introduced and the Pro/E, through its characteristics, we can understand the Pro/E in the development of social production industry, and their importance from a new perspective of production needs and future development direction, let us keep production steps, also remind us to do old old, Chapter 2 is the basic knowledge of computer and the use of some brief introduction, The third chapter is based on the PRO/E computer modeling design, highlight the thesis processing product modeling process of software and application software of parting. Through this chapter can understand the PRO/E, understand the application of PRO/E modeling and manufacturing partial function,
This design from reality and systematically introduced based on PRO/E, function module, the concave-convex application instructions and CNC processing method and relevant operation. Through the detailed process and lots of pictures, teachers and fellow leaders clearly understand PRO/E product design functions.
Because of my limited, design of existing shortcomings and errors unavoidably, your teacher correct.
1. A ISA 母线是设计在母板 motherboard 上的。
2. B 机器语言 machine language 是最快的。
3. C boot 是“启动程序”。routine 就是“例行程序”的意思。
4. B 那个就叫 boot sector,“引导扇区”。
5. A 队列 queue 是先进先出 FIFO。
6. C 链表 linked list 的节点 node 由数据字段 data field 和指针 pointer 组成。
7. B 编译器 compiler 是程序开发用的,不属于办公室自动化工具。
8. D SCSI 是周边连接的标准,中央处理器 CPU 不用。
9. B 调制解调器 modem 用于通过电话线的电脑通信。
10. A Word 2000 是文字处理器。
11. C 字符串 string 是字符的数组;数组是结构数据类型。
12. B 栈结构 stack 只允许栈顶 top 数据存取。
13. 题目有问题,四个选项都是扩展卡 expansion card,要选的话选 D 吧。I/O card 有些人不知道。
14. A 计算和 calculate the summation 是数学公式 math formulas 的一个功能,其他三个不是。
15. C 压缩包 ZIP file 里可包含一个或多个文档。
16. B WinRAR 是压缩软件 compression software,其他三个不是。
17. D 自解压文档的扩展名是 .exe。
18. A 塑料 plastic 不是传讯媒质。
19. B 把电脑闭环 closed loop 连接的网络叫做环形拓扑结构 ring topology。
20. 题目不完整,没有 C、D 选项。A 和 B 都是多媒体系统所需要的,不是答案。
