ＳＢ－ＹＺＣＰ人工降雨模拟装置经５年研制、３年应用、３万个数据率定，计算确定了该装置特性的关系式：（１）喷射中心（Ｌ）～喷孔直径（Ｄ）～工作压强（Ｐ）的关系式；（２）降雨均匀系数（Ｋ）～Ｄ～面积（Ｓ）的关系式；（３）平均降雨强度（Ｉ）～Ｓ的关系式；Ｉ～Ｄ～Ｐ的关系式；（４）平均雨滴动能（Ｅ）～Ｄ～Ｐ的关系式；（５）雨滴中数直径（Ｄ５０）～Ｄ～Ｐ的关系式；（６）Ｅ～Ｄ的关系式。经模拟不同雨型、不同植被的水保效益试验，检验了机械性能、降雨特征及模拟效果。经检定认为：该装置性能稳定，观测数据精确可靠，自控部分运行灵敏、降雨特性与天然降雨特性别无它样，是我国目前较先进的野外移动降雨装置。
SB-YZCP artificial rainfall simulation device developed by 5 years, 3 years of application, 30,000 data rate set to determine the relationship between the characteristics of the device: (1) injection center (L) ~ nozzle diameter (D) ~ work (P); (2) the relationship between the rainfall uniformity coefficient (K) ~ D ~ area (S); (3) the relationship between the average rainfall intensity (I) ~S; ; (4) the relationship between the average kinetic energy of the raindrops (E) ~ D ~ P; (5) the relationship between the median diameter of the raindrops (D50) ~ D ~ P; After simulating different types of rain and soil conservation benefits of different vegetation, mechanical properties, rainfall characteristics and simulation results were tested. The test shows that: The device is stable, accurate and reliable observation data, automatic control part of the operation is sensitive, the rainfall characteristics and natural rainfall characteristics have nothing to do with it, is China’s more advanced field mobile rainfall device.
