在规划和控制配水系统中的水质时，了解网络中水性物质的时间历史和最终的空间分布非常有用。本文描述的工作涉及模拟水性物质在一般分配网络中的传播和最终分布的水力方面。一个例子演示了这种模型的用法。利用计算机图形学给出了仿真结果。包括6个参考文献、图表。

In the planning and control of water quality in distribution systems, it is useful to know the time history and eventual spatial distribution of waterborne substances in the network. The work described here addresses the hydraulic aspects of modeling the propagation and eventual distribution of waterborne substances in general distribution networks. An example demonstrates the usage of such a model. Computer graphics are employed to present the simulation results. Includes 6 references, figures.
