中文摘要：

针对当前远程教学平台实际应用中存在的系统功能有限、性能低下等缺陷，探讨了．NET智能客户端技术的特点及其优越性，提出了基于智能客户端的远程教学系统的多层次模型设计方案，并对该模型实现的关键技术进行了探讨。智能客户端能够实现强大的用户界面，数据的安全访问，便捷的部署和升级，这些特性都是传统客户端无法比拟的。基于智能客户端的远程教学系统能够加快对用户请求的响应速度，降低服务器的处理负载，支持在线和离线两种工作状态，还可以实现集中部署和自动更新等功能。

英文摘要：

Points out the existing problems of current e- learning system, such as the limited of the system function, bad performance and so on. Then discuss the characteristic and advantage of. Net sTnart client technology, and put forward a designing solution of multi - layers e- learning system based on the model of emart client,also discuss the implementation of the key teclmique. The smart client can perform the strong user interface, the safe access of date,and easy to deploy and update. The system based on the smart client can accelerate the respond of the user＇s request. It can be work whatever online or offline. The deploy and auto update also can be implemented.
