落速 meaning in Chinese

[物理学] terminal-velocity

The influence of the cloud droplet spectrum character and the spectrum growth and change is considered , which does not use a cut - off value for conversion from cloud water into rain water process . in the continuous coalescence equation , the particles fall velocity difference is not moved out from the integral , but is integrated in the equation as the function of diameter d to avoid the error of using particles average fall velocity . in the new scheme , generation rate of graupel due to the collection of snow by graupel and the collection of cloud ice by graupel are included
云中凝结核ccn的数浓度采用超几何函数表示；云水向雨水的自动转换过程采用grabowski ( 1999 )的公式，考虑了云滴谱的特征和发展变化对该过程的影响，而不是采用原方案给定阈值的方法描述该过程；对连续碰并方程不再将粒子落速差作为常量提出积分号外，而是直接作为粒子直径函数在积分号内求解，这样处理可以回避使用粒子群的平均落速带来的误差；增加了霰和雪、霰和冰晶的碰并微物理过程。
