| 摘 要： | “平水头法”是均匀坡下微灌毛管水力设计中一种简单易行的方法。该方法根据流量指数x和允许压力偏差率在特定范围内灌水器平均流量所对应的压力与平均(设计)压力近似相等的原理,建立端压与均压间的关系式,以压力设计结果代替流量设计结果。通过相对误差分析,证明了这种方法在实际应用中的可行性。

| Abstract: | "Average water head Method"is a simple method for hvdraulic designing mini-irrigation Lateral. This method is based on the principle that the pressure corresponding average flow rate equals average (design) pressure approximately when flow rate index x and permissive deviation of pressure are in a special range. Deviation analysis proves the feasibility of this method in practical application. |
