| 摘 要： | 借助于各种各样的傅里叶变换，探讨了农田喷灌旋转喷头组合均匀度计算的新方法，使克里斯琴森均匀度系数用单喷头水量分布、支管间距、喷头间距、布置形式以严密的数学表达式加以表述.最后用一组实测数据和该方法进行计算对比，证明该方法可用于实验工作中.

| Abstract: | Various Fourier transforms have been applied to investigate the new calculation method for sprinkler overlapping uniformity.The uniformity coefficient is described by a mathematical expression with parameters including water distribution,spacing,orientation,etc.The result of an example is compared with the observation data.It demonstrates that the new method is feasible for practical use. |
