coalescence rate meaning in Chinese

聚集速率
聚结速率

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
当液滴初始直径较小时，其集聚变化率随着初始直径的变化而急剧变化；提高螺杆转速和降低挤出机产量有利于集聚的发生，分散效果较差。
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
结果表明，当液滴初始直径较大时，其集聚变化率随着初始直径的变化而变化较小；提高螺杆转速和降低挤出机产量可以提高螺纹元件的分散效果。
