摘　　要：传统的在线学习交流系统采用同步交互方式，响应速度慢，效率低下。该文采用基于DWR框架的推技术，将在线学习中的新内容主动推向客户端，从而降低了服务器负载，提高了系统的访问效率，增强了系统的实时性和交互性，能有效地激发学生在线学习交流的积极性。Traditional online learning and exchanging systems use synchronous interaction way, which result in slow response and low efficiency. Through using push technology which is based on DWR framework, the server can send the new content to client actively. And the efficiency of the system can be improved; the feature of real-time and interactive can be enhanced; while students＂ enthusiasm on online learning communication system is improved.
