摘　　要：针对传统的基于两层客户/服务器(C/S)汽轮机寿命管理系统维护困难、扩展性差、操作复杂的缺点,应用MicrosoftWindows分布网络应用程序构架DNA(DistributedInterNetApplicationsArchitecture)建立了一种新的系统。该系统是一个典型的三层应用程序,可以明确地分为表示层、应用逻辑层和数据服务层。因此不必在每一个终端安装胖客户端应用程序,电厂运行人员在各终端只要使用Web浏览器(如InternetExplorer)就可以在启停或变负荷时对汽轮机的关键部件(如转子、汽缸)的寿命损耗进行监测。实践证明,采用这种构架创建的汽轮机寿命管理系统具有操作维护简单、运行稳定和升级方便等优点。Because the traditional stream turbine service life management system based on C/S is difficult to maintain,extend and operate,a new system using Windows DNA is introduced.This system is a typical3-tier application and can be divided into presentation,business logic and data layer.Therefore,the fat client application on terminals is not needed.The key parts of stream tur-bine(such as the rotor and the cylinder)can be monitored with Web browser(such as Internet Explorer)through Internet by the operators and managers.The practical application shows that the proposed system has many advantages,such as easy operation and maintenance,stable running,easy upgrading,etc.
