摘要： 并行、分布式系统应用日益广泛，但它的开发却很困难，可视化是其解决方法之一。给出了一个以面向对象的分布式程序设计语言NC＋＋为基础的可视化分布式程序设计的基本模型VGOM，将一个分布式程序的特征用图加以描述；同时在原有NC＋＋语言基础上增加了高层的基于图结构的图操作原语，包括通信原语等，从而提供结构化的通信方式。在SUN工作站上，使用Motif与PVM实现了该模型。

Abstract: The parallel, distributed system has been widely applied, but its development is still a greatdifficulty. Visualizatinn is one of the solutions. This paper proposes a distributed visual programming model based on the object-oriented distributed language NC＋＋.It describes a distributed program's characteristics by graphs.Furthermore, it supplies a set of high-level graph operations based on some graph constructs, including communication primitives, so to offera structured con1munication.We have implemented the model on the Sun workstation by Motif and PVM.
