提出了一种简单、准确的设计单根、成对、锥形微灌管路的方法。采用侧向流量方程方法对支流的水力学进行了评价。用一个简单的功率方程表示进口流量与侧向进口压头之间的关系。将流量变化控制在规定的极限范围内，建立了变截面长度的设计程序。侧向的设计采用了分步的方法。锥形截面的长度由黄金分割搜索法确定。
A simple and accurate method is developed for designing single, paired, and tapered microirrigation laterals. The hydraulics of the lateral is evaluated using a lateral discharge equation approach. A simple power equation is used to express the relationship between the inlet flow rate and inlet pressure head of the lateral. Keeping the flow variation within the specified limit, a procedure for designing the length of the tapered section is developed. The lateral is designed using a step-by-step method. The length of the tapered section is determined by the golden section search method.
