基于Delphi的试卷智能生成系统设计
 
摘要：运用可视化软件Delphi来开发试卷智能生成系统。是利用其提供的各种面向对象的开发工具来建立系统应用原型，然后进行需求迭代，通过不断修正和改进，直到形成满意的可行系统。该系统结构良好、使用方便、题库数据输入简单,系统能够实现自动抽题和手动选题两大功能。 开发内容包括后台数据库的建立、维护以及前端应用程序的设计两个方面。该系统有安全的用户登录模块、易于操作的功能模块以及方便快捷的浏览界面。本文的分析基于知识点的试题库结构基础上，阐述以知识点难度系数、章节、题型为主要控制参数的组卷算法的建立与实现方法。该系统的运用不仅提高了教师的工作效率,而且可以实现真正意义上实现了便捷性与智能性。经测试表明本软件在Windows 2000/XP平台下程序运行稳定且各项功能运行得都很正确，基本达到了预期的要求。

Automatic generated paper system based on Delphi
 
Abstract: Use vitrification software of Delphi to empolder an automatic generated paper system, mainly use its various object-oriented application development tools to build a prototype system, and then progress to the demand analysis, through inconstant revision and improvement, until a satisfactory and viable system come into being. The system is well structured and user-friendly, with simplification of data input to the databank, the system has achieved two functions of fully automatic selection of subjects and manual selection of subjects. The development of the background Database includes the establishment, maintenance and front-end application design. The system has a security users download module, user-friendly and convenient functional module browsing interface. The analysis in this paper is based on knowledge of the structural basis of the examination on the knowledge factor is the difficulty, chapters, sections for the main control parameters Zujuan algorithm and the realization of the establishment. The system is used not only to improve the efficiency of the work of teachers, but also achieve a true sense of sexual and convenient wisdom. Testing shows the software platform in Windows 2000/XP stability and operational procedures of the functional operation of a very correctly, the basic met expectations. （科教作文网 zw.nseac.com整理）
