摘　　要：对试题库系统的几个关键问题进行了研究,实现了在WEB页面中嵌入WORD录入和编辑试题,支持复杂对象的混排,实现了试卷排版自动化.针对自动组卷中产生的试题堆积、分布不合理问题,提出了一种改进的自动组卷算法,通过动态监控各章节的可分配分值范围,对已抽取试题的分布情况进行评估,确定最佳的选题子集,再从该子集中随机抽取试题,从而避免了自动组卷产生的试题堆积现象,本算法能生成更加科学合理的考试试卷.Several key questions for establishing the examination question system are studied.It can help embed the WORD into the WEB page,and thus use it to log and edit the questions.It supports the mixed arrangement of complex ob-jects,and realizes the automatic layout of papers.In order to rid of the problem of questions accumulation and irrational distri-bution in the automatic generating paper,an improved algorithm of automatic generating paper is proposed.By means of dy-namic monitoring of the range of the distributable values,the distribution of the sampled questions can be evaluated and the op-timal subsets of the selected questions are determinated and then a random sampling can be made from the subsets of ques-tions.Such a method can successfully rid itself of the problem of questions accumulation commonly found in automatic test pa-per generation.Examination papers generated by this algorithm are more scientific and rational.
