摘　　要：对变质量雨滴的下落过程进行了研究,建立下落雨滴的动力学方程,用理论推导求解析解,并用计算机编程求解数值解,结果表明理论分析与数值结果一致。The whereabouts of the raindrops with variable quality is studied and its dynamic equation is proposed. Theoretical results are derived by inferring the differential equations theoretically and the numerical results are derived by simulating in computer. It is indicated theoretical results are in agreement with numerical simulation results.
