传输线方法是对管道中的流动进行动态建模的一种非常有效的方法，并使用延迟元素来表示波传播。在本文中，对现有的传输线方法模型进行了研究，并发现其存在一些缺陷。引入了一种替代技术来提高瞬态和稳态精度。这种新的传输线方法和分析模型之间获得了非常好的一致性。该模型已在许多高动态系统的仿真中得到实现，并且被发现是稳健且可靠的。
The transmission line method is a very efficient method for dynamic modelling of flow in pipelines and uses delay elements to represent wave propagation. In this article, an existing transmission line method model is investigated and shown to have some deficiencies. An alternative technique is introduced to enhance the transient and steady-state accuracy. Extremely good agreement is obtained between this new transmission line method and an analytical model. The model has been implemented in simulation of a number of highly dynamic systems and has been found to be robust and reliable.
