摘　　要：作为职业技能鉴定网络考试系统中的重要组成部分,试题库系统需要解决几个关键问题:存储和显示包含多种媒体信息形式的试题;从试题库中抽取出符合要求的试卷;生成Word文档形式的试卷文件。因此提出了试题库系统的工作流程和整体结构设计;设计并实现了以自定义控件的方式录入复合文本形式试题,通过生成临时RTF文件将试题写入数据库;设计了基于贪心策略的抽题组卷算法,阐述了以组件对象模型(COM)技术的自动化机制,利用Word提供的接口,实现试卷输出的方法。The testing questions library system,essential element of on-line examination system for occupational skill appraisal,is demanded to solve the following main problems： saving and displaying test questions containing information of multimedia,drawing test papers according to the requirements from the library,and generating the Word test papers.In this thesis the work flow and overall structure design of the system was presented,the way of inputting compound-text test paper by using custom control was proposed and realized,meanwhile test questions were written into the database by creating the RTF files,the greedy-strategy-based algorithm for test paper drawing questions and organizing papers was designed,and the output of test papers with COM-based automation mechanism by using Word-offered interface was clarified.
