对人工降雨系统中喷头的特性进行了建模仿真，根据喷头在不同压力下雨强分布的数据，拟合出了雨强与半径的关系曲线，并验证了建模的准确性。用多种类型的喷头进行组合降雨，实现了降雨的连续变化，并且利用多个喷头有效喷射半径之间的重叠来达到降雨均匀度的最大均匀。编制了人工模拟降雨仿真软件，通过对比分析两种喷头布局，最终喷头确定为正方形布置，大大地提高了降雨的有效面积。对喷头的选取和布局及人工降雨系统的研究有重要的指导意义。

The characteristics of nozzle in artificial rainfall system are modelled and simulated. According to the rain intensity distribution data of the nozzle under different pressures, the curve of the rainfall intensity and the radius is obtained. A plurality of nozzles are used to realize the rain intensity change continuously in the range, the overlap of the effective muhi-nozzles radius is used to rain uniformly. A detailed design of the artificial rainfall simulation software is provided. Through the comparative analysis of two layouts, the square arrangement is selected, which can greatly improve the effective area. It provides important guiding significance on the selection and layout of the nozzle and research on artificial rainfall system.
