运用可视化Delphi开发出试题自动生成系统.利用其提供的各种面向对象的开发工具, 建立系统应用原型，然后进行需求迭代，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,系统能够实现人工选题和随机抽题两大功能. 包括后台数据库的建立、维护以及前端应用程序的开发两个方面。该系统有安全的用户登录模块、方便快捷的浏览界面、易于操作的功能模块。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和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通用性。

Delphi has developed the use of visual examination questions automatically generated system. Provides a variety of its object-oriented development tools to build a prototype system application and then demand iterative, constantly revised and improved, until the formation of a satisfactory workable system. The system is well structured, easy to use, simple data entry item bank, the system can achieve artificial subject matter and random questions two broad functions. Including the establishment of back-end database, front-end application maintenance and development of two aspects. The system has the safety of the user login module, convenient browsing interface, easy-to-operate functional blocks. This paper''s analysis is based on knowledge point based on the structure of the test database, presents the knowledge points and the kinds of questions the coefficient of difficulty as the main control parameters of the test paper the algorithm the establishment and realization method. The use of the system not only improve the efficiency of teachers, but also a real sense of versatility.
