    摘要:

    在文獻(xiàn)[10]提出的流量偏差率公式基礎(chǔ)上，作了進(jìn)一步推導(dǎo),，簡(jiǎn)化了公式中的參數(shù),。根據(jù)步進(jìn)法水力解析原理,，模擬了不同制造偏差下給定灌水小區(qū)的綜合流量偏差率，通過(guò)對(duì)綜合流量偏差率的統(tǒng)計(jì)分析,，驗(yàn)證了理論公式,。利用公式分析了制造偏差對(duì)綜合流量偏差率的影響，提出了灌水小區(qū)綜合流量偏差率允許值的建議,。

    Abstract:

    Based on the formula of flow deviation rate proposed by authors in reference [10], the further derivation was conducted to simplify the parameters in the formula for designing drip irrigation system economically and credibly. According to the hydraulic analysis using step-by-step method, the integrated flow deviation rates for a drip irrigation submain unit were calculated at different emitter manufacturing variation. The formula of flow deviation rate was verified by the statistical analysis of the integrated flow deviation rate. Further, the effect of emitter manufacturing variation on integrated flow deviation rate was analyzed using the formula, and the allowable value for integrated flow deviation rate of drip irrigation submain unit was recommended for drip irrigation system design.
