调压灌溉系统压力动态变化过程简化计算模型的研究

Resarch on the Caculating Model of Pressure Tendency of Adjusting Pressure Irrigation System

本文以恒定流模型为基础，采用一次差分近似及线性化处理，建立了调压灌溉系统压力动态变化过程的简化计算模型，经与非恒定流模型比较，简化模型具有较高的精度，计算简便、快捷。

Based on steady flow model,using one approximate and linear first derivative equation,the paper establishes a mathematical model of pressure tendency of adjusting pressure irrigation system.Compared with the unsteady flow model,this model has a great accuracy and is easy to use.
