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
雲中凝結核ccn的數濃度採用超幾何函數表示；雲水向雨水的自動轉換過程採用grabowski （ 1999 ）的公式，考慮了雲滴譜的特徵和發展變化對該過程的影響，而不是採用原方案給定閾值的方法描述該過程；對連續碰並方程不再將粒子落速差作為常量提出積分號外，而是直接作為粒子直徑函數在積分號內求解，這樣處理可以迴避使用粒子群的平均落速帶來的誤差；增加了霰和雪、霰和冰晶的碰並微物理過程。 -
When the dispersed phase droplet initial diameter was relatively small, the coalescence rate varied sharply as the dispersed phase droplet initial diameter changed, the coalescence effect was dominating with increasing the screw rotation speed and decreasing the output
當液滴初始直徑較小時，其集聚變化率隨著初始直徑的變化而急劇變化；提高螺桿轉速和降低擠出機產量有利於集聚的發生，分散效果較差。 -
The results showed that when the dispersed phase droplet initial diameter was relatively large, the coalescence rate little varied as the dispersed phase droplet initial diameter changed and increasing the screw rotation speed and decreasing the output could obviously make for the dispersed effect
結果表明，當液滴初始直徑較大時，其集聚變化率隨著初始直徑的變化而變化較小；提高螺桿轉速和降低擠出機產量可以提高螺紋元件的分散效果。
