1、毕业设计（论文）题 目 C语言课程教学网站的设计与实现 学 院 专业班级 学生姓名 指导教师 成 绩 2012 年 06 月 16 日and performance test copies of the record. If necessary, review should be carried out; 4) for spring hangers (included simple spring, hangers and constant support hangers) it should also be recognized as setting and locking of loads.
2、 5) check the surface quality, folded layering and without cracks, rust and other defects. 5) after completion of the test and control drawing number one by one, by series baled. Color alloy steel parts, the parts marking installation location and rotation about the direction you want. 7.3.14. hange
3、rs installation 7.3.14.1 hanger layout a. a clear design of hanger should be installed strictly in accordance with the drawings and designs shall not be installed wrong, missing, etc. B. own arrangement of piping support and hanger set and selection should be based on comprehensive analysis of gener
4、al layout of piping systems; cold installation of steam pipe with particular attention reserved for compensation of thermal expansion displacement and orientation. C. support systems should be rational to withstand pipe loads, static load and incidental load; reasonable piping displacement; guarante
5、ed under various conditions, stress are within the allowed range. Strength, stiffness, and meet requirements to prevent vibration and soothing water, without affecting the adjacent equipment maintenance and other piping installation and expansion. D. equipment connected to the interface to meet pipe
6、line thrust (torque) limit requirements; increase the stability of piping systems to prevent pipeline . Tube wall thickness (mm) 2-3 4-6 7-10 weld form no slope mouth weld strengthening height h (mm) 1-1.5 1.5-2 weld width b (mm) 5-6 7-6 has slope mouth weld strengthening height h (mm) 1.5-2 2 weld
7、width b (mm) cover had each edge slope mouth about 2 mm argon arc welding weld strengthening surface height and width tube wall thickness (mm) 2-3 3-4 5-6 weld form weld strengthening height h (mm) 1-1 .5 1.5-2 2-2.5 width b (mm)摘 要Internet作为全球性的计算机互联网，已深入到人们日常生活当中。现代教育技术的发展，使得学生学习的方式发生了巨大的变化，连上课的方式
8、也不再只拘泥于传统的方式。网络教学系统的广泛应用，突出了学生在网上教学活动中的主体作用，为学习者在课堂上实现“建构学习”提供了可能。 根据C语言这门课程的特点和要求，采用了 ASP+DIV+CSS 的设计模式，并采用 B/S 模式结构，利用 MD5加密进行了系统与总体数据的规划、设计与实现。并结合Dreamweaver实现静态网页界面的设计。本系统使用的ASP.NET动态网页技术以及SQL SERVER数据库技术都已经发展成熟，完全可以满足系统设计需要，而且是目前主流技术，服务器的架设和支持均十分方便。 经过测试表明，建立一个符合学校教学要求的使用网站，可实现课程描述、在线学习、师生互动模块等
9、功能，同时能够提供一定的安全机制，提供数据信息的授权访问。关键词：教学网站；网络教学；动态网页AbstractInternet is global computer Internet , already has gone deep into to people daily life middle.
