| 摘 要： | 该文采用数理统计学方差估计理论，针对全补偿微灌系统的灌水均匀度系数进行了研究分析，从理论上推导出全补偿微灌系统均匀度系数与流量偏差系数之间基本关系式，同时采用传统的随机数字模拟方式对导出的公式进行了验证和分析，并且探讨了均匀度系数和流量偏差率之间的关系规律，最后通过实例说明了上述公式的运用价值。该研究成果为全补偿微灌系统的设计、工程灌水均匀度评价和补偿式灌水器制造偏差控制等提供了参考依据。 |
| 关 键 词： | 灌水均匀度 流量偏差系数 微灌系统 |

| Abstract: | Based on the theory of variance estimation of mathematical statistics, the parameters of irrigation uniformity in full equalizing micro-irrigation system were studied and the relational expression between coefficients of the irrigation uniformity and the flow deviation were proposed. At the same time, the formula was validated using simulation method with conventional random numbers and the relationships between the coefficients of irrigation uniformity and the flow deviation were discussed. The application worth of the formula was indicated through an example. The research provides reference for the plan of micro-irrigation system, appraising irrigation uniformity and controlling manufactuerable deviation of equalizing emitter. |
| Keywords: | irrigation uniformity flow deviational coefficient micro-irrigation system |
