| 摘 要： | 在分析、借鉴国内外研制经验的基础上,研制单喷头曲面设计、双层喷射变雨强弹簧调节的野外模拟降雨喷头,实现了以单喷头替代多喷头组合式模拟降雨装置,并达到同样模拟降雨效果。由于喷头采用曲面设计,确保喷射水舌有规律地变化;模拟雨滴动能接近于天然降雨动能;模拟降雨过程均匀;喷射面积稳定。实测证明:雨滴中数直径为0.574.26mm,降雨均匀系数≥0.8（±0.05）,降雨面积为150 m2,模拟降雨强度为30～240 mm/h。

| Abstract: | On the basis of the internal and external experiences,a single-spraying head simutator with curved-surface,double-lager,variable rainfall intensity spring was developed.Because of the curved-surface design,it can make the water tongue move regularly,so the artificial rainfall is just as like as the natural rainfall.The simulated rainfall process is well-distributed and spraying area is stable.The experiment showed that the mid-raindrop size is of 0.574.26mm,rainfall area is of 150m2,and simulated rainfall intensity ranged 30240mm/h. |

| Keywords: | simuated rainfall comparative law coefficient of eveness rainfall intensity stability |
