摘　　要：组卷和试卷测评是网络考试系统的核心内容,为此,在深入研究的基础上,提出了基于难度级别的分割递归算法和状态链表的随机抽题算法,实现了快速组卷过程。基于该组卷方式,介绍了试卷的4个主要评测指标。最后给出了具体实例加以论证。该算法已经成功应用于实际网络考试系统中。Generating paper and analyzing paper are the core content of the net examination system. On the basis of researching on these, a division-recursion algorithm based on the level of difficulty and a algorithm of randomly drawing out test questions based on the state-chain-table are presented. The generating paper process is realized. Based on the way of generating paper, four main standards of measure are introduced. Finally a specific and fact example to proof them is provided. The algorithms are successfully used in actual net examination system.
