摘　　要：针对采用"单击,等待"交互模式的远程教育平台存在整页刷新的问题,研究Ajax工作原理及典型的Ajax框架,着重分析Ajax在远程教育平台的考试模块、试题录入模块、留言簿模块的应用,避免服务器在网络上向客户端发送那些没有改变过的信息,使得应用程序更为迅捷地回应用户动作。实验表明:Ajax技术的应用提高了系统的响应速度。There is a full-page refresh problem on the distance education platform based on ＂click, wait＂ interactive mode. Ajax principle and some typical Ajax frameworks are studied. Ajax is applied in the examination module, inputting questions module, visitors book module of the distance education platform to avoid information without change being send from the server to the client through the Internet. It makes the application more rapid response to user action. Performance tests show that： Ajax technology really improves the response speed of the system.
