摘　　要：采用滤纸色斑法对沈阳市天然降雨雨滴进行观测,通过计算并运用回归分析对沈阳地区天然降雨雨滴特性进行研究。结果表明:沈阳地区天然降雨雨滴的大小分布遵守Best函数分布式;雨滴中数直径及降雨动能同降雨强度关系显著,呈幂函数关系。The natural raindrop was observed with filter-color stain method in shenyang city. The characteristics of natural raindrop was studied by computation and using statistical analysis. The results indicated that the distribution of natural raindrop size was coincidented with Best＇s function in shenyang city. The median raindrop diameter and the kinetic energy of rain had significant relationship with rainfall intensity and expressed significantly degree dependence.
