结合广东省台山市进行的水稻种植区控制排灌田间工程项目 ,对自动给水栓灌溉系统的非均匀出流问题进行了研究。利用最速下降法、牛顿迭代法求解非线性方程组的方法 ,探讨了在一定的总水头、不同的给水栓开启情况下各个出水口流量的数学分析方法 ,从而为这套灌溉系统的设计和运行管理提供了科学的依据 Combined with the field control of irrigation and irrigation fields in rice planting areas in Taishan City, Guangdong Province, the problem of non-uniform outflow in automatic irrigation system was studied. Using the steepest descent method and the Newton iterative method to solve the nonlinear equations, the mathematical analysis method of the flow at each outlet with a certain total head and different water supply plugs is discussed, and the design and operation of this irrigation system Management provides a scientific basis
