摘　　要：以对等网络为基础,利用JXTA平台建立一个分布式的、可交互的、资源高度共享的平面几何辅助教学系统.系统包括了对等组管理、组内成员信息管理、电子白板和即时消息等模块.系统中利用Java绘图技术,在电子白板的模块中,集成了图形绘制环境,可以绘制基本的平面几何图形和几何符号;并实现图形的即时通信,实现用户间实时的共享电子白板内容.即时消息模块分为组内聊天和一对一聊天.This study analyzed the existing CAI systems and their trends, and then built a distributed, interactive, highly resource sharing Plane Geometry＇s computer- aided instruction system of P2P mode with JXTA platform, which included PeerGroup Management, the Members＇ Information Management, an interactive Whiteboard and an Instant Messaging module. In the system＇s whiteboard module, firstly, a graphic toolkit was developed to draw geo- metric graphics and symbols by using JAVA graphics technology; secondly, graph - based instant communication was implemented and users could share the board＇s information. The Instant Messaging included a members＇ discussion module and a one -to -one online chatting module.
