摘  要:
以单喷头喷洒测试数据为基础,按照水量叠加原理,通过对单喷头喷洒区域的虚拟扩展、典型代表区域和计算区域的设定等,详细介绍了利用Surfer 11软件计算三角形组合喷灌均匀度的计算方法与步骤。通过对算例分析表明,利用Surfer软件最近邻点插值法进行数据网格化处理的有效性最好,并且数据网格跨度大小对计算结果影响不大,取0.5较为合适。

摘  要:
On the basis of the test data of single sprinkler spraying,and according to the water superposition principle,through the virtual extension of the single sprinkler spray area and the setting of typical representative region and calculation domain,the calculation method and steps of triangle sprinkling irrigation unit uniformity by Surfer 11 software are introduced in detail. Through the analysis of calculation examples,it is shown that the nearest point interpolation method of Surfer software is the best method for data grid processing,and the data grid span size has little influence on the calculation result,and 0.5 is suitable for it.
