| 摘 要： | 在传统的喷灌支管设计中,支管上各喷头等间距布置,但是沿支管灌水量不相等。为此提出一种实现沿支管灌水量相等,但允许喷头间距变化的支管设计方法。采用这种设计方法可以提高喷灌灌水均匀度,并且能在不增加用水量和不均加能耗的情况下,增加支管灌溉面积。最后给出一个算例,说明这种方法的计算过程及应用效果。

| Abstract: | A new designing method for sprinkle-irrigation laterals, in which the spacing of sprinklers can be changed with the outflow of sprinklers along the lateral, is developed. By use of the suggested method, the irrigation uniformity of sprinkle-irrigation can be considerably improved and the irrigation area can be increased to a certain extent. An example is presented to explain the application of the designing method and to show its effect. |
