国外管道仿真技术发展状况

计算机仿真技术已在管道工业中的设计、运行管理和人员培训等方面得到了广泛的应用。管道仿真软件为动态水力工况分析、确定运行方案以及管道泄漏的检测和分析等提供了强有力的工具。从离线仿真和在线仿真（实时仿真）两个方面，分别介绍了国外管道仿真技术的发展及其应用，并着重介绍了在线仿真软件的各模块功能以及它们之间的联系。

The Development of the Simulation Technology of Foreign Pipeline

The computer simulation technology has been widely used in the pipeline design,operating management and staffs training in the pipeline industry. The simulating software of pipeline provides a powerful tool for the dynamic analysis of hydraulic characteristics and the determination of operating plan,as well as the detection and analysis of pipeline leakage. In the on-line (real time simulation) and off-line simulation, the development and application in the simulation technology of foreign pipelines are respectively introduced, and especially the models'functions of on-line simulation softwares and relationships between them.
