| 中文摘要: |
| 本文针对喷灌系统三角形布置的单喷头组合均匀度叠加计算问题，提出以矩形等效面积代替三角形面积的计算方法，建立了将单喷头辐射线布置雨量筒实测数据准确转换为方格形布置数据的模型和叠加计算的数学模型，从而可以用单喷头实测水量分布进行均匀度叠加计算。根据数学模型编制了数据转换和叠加计算程序。以PY1-20单喷头实测数据进行实例计算，结果表明，用本文模型进行三角形喷头组合的均匀度叠加计算既方便又快捷。 |
| 英文摘要: |
| To solve the problem in overlapping computation for water distribution uniformity of sprinkler system based on water distribution data of single sprinkler, the method of using the equivalent typical-area of rectangle to replace the typical-area of triangle is proposed. The mathematical model and computer program are developed. Thereby, the computation can be carried out according to the measured distribution of single sprinkler. An example is given for demonstration. |
