摘要
超文本（Ｈｙｐｅｒｔｘｔ）是一种信息管理技术，它是采用符合人脑思维模式的联想机制对庞大信息量进行检索的一种非线性结构。超文本技术由节点（Ｎｏｄｅ）与链（Ｌｉｎｋ）组成，其系统结构分为数据库层、抽象机层与表现层三个层次，同时，它支持多个用户在同一组超文本数据上共同操作，称为协作超文本。
Hypertext is a kind of technique for information management which is a nonlinear structure for retrieval of enormous amount of information by using associative mechanism in conformity with thinking mode of human brains.Hypertext technique is composed of nodes and links the system structure of which can be divided into three levels:database level,abstract machine level and manifestation level.At the same time it can support users to operate commonly on the same group of hypertext data which is callde as cooperating hypertext.
