The character of water distribution with punched thin soft spray tape was studied. According to the obtained data from punched thin soft spray tape and single hole sprinkling trial(designed trial angle of sprinkling water is from 10 degree to 90 degree), certain non linear mathematical models of punched thin soft spray tape single hole of distributing water of single apex and double apices are made by using data fitting method of DUD arithmetic. Except 10 degree and 90 degree sprinkle...             为研究微喷带喷灌水的分布特征 ,依据微喷带单孔喷灌试验得到的数据 (喷水角度以 10°～ 90°设计试验 ) ,采用 DUD非线性数学模型的数据拟合方法 ,确定了微喷带单孔喷灌水分布的单峰和双峰的非线性数学模型。除 10°和 90°外 ,其他喷水角情况下采用双峰模型的拟合精度均明显高于单峰模型。由拟合模型的回归平方和与残差平方和可以看出 ,模型的拟合精度都很高 ,表明采用本文中的非线性数学模型 ,可以较好地描述微喷带喷灌水的分布。这对于进一步精确确定土壤水运动分布状态 ,同时对于优化设计微喷带设施都具有重要的指导意义 文摘来源          A complete assessment criteria system for water saving irrigation is established by using the systematic fuzzy comprehensive assessment entropy model and combining with practice. 5 kinds of water saving irrigation methods, namely, border irrigation, micro - spray tape irrigation, mobile sprinkler irrigation, semi-fixed sprinkler irrigation and fixed sprinkler irrigation, for improved low-pressure water-transfer pipeline are comprehensively appraised through model application. Meanwhile, the problems o...             在建立完善节水灌溉综合评价指标体系的基础上,应用构建的系统模糊综合评价嫡权模型并结合实际,对低压管道输水改进的畦（沟）灌、微喷带灌、移动式喷灌、半固定式喷灌和固定式喷灌5种节水灌溉工程技术形式进行了综合评价,并对喷灌的发展问题做了进一步探讨。 文摘来源          The principle and structure of a new type of double_wall drip tape are introduced. The hydraulic properties, design characteristics and field application design are researched, and the situation of field application and its benefit are also analyzed. It is concluded that the thickness of this product is 0.15～0.25 mm, the explosion pressure is 450 kPa, the uniformity of water application is above 90 %, and the fluid state index is 0.77.
