摘　　要：介绍了多层分布式应用系统的概念,分析了影响多层分布式应用系统效率的关键因素,指出在开发分布式多层应用系统时,为了有效提高多层可用系统的执行效率,应采用最有效率的远程调用和降低网络数据的传递负荷,减少网络的Roundtrip,调整应用程序服务器的执行效率,选择合适的通信协议,控制应用程序的线程模型和加强应用程序服务的容错及平衡负载能力等方法来构建分布式应用系统。实际开发应用表明,结合了该开发方法的分布式应用系统的执行效率在很大程度上得到了提高。The concept of multitier distributed application systems was introduced and analyzed these key factor that impact efficiency of the distributed application systems.It is indicated that developers should use the approaches of the most effient longdistance transfer and reducing the passing charge of network data during the course of their development in order to enhance the executive efficiency of application systems.It is proved practically that the executive efficiency of the distributed application systems utilized the methods is improved evidently.
