Initially dr antonopoulou and her colleagues found that the coulombic efficiency of their cells-a measure of how many electrons produced actually flow into a circuit-was particularly low , at around just 2 % .

首先antonopoulou博士和她的同事发现其实那些电池的库伦效率（电路所实际产生的电子量与流经电路的电流之比）是非常低的，只有2%左右。

The result indicates that for enhancing particle target collection efficiencies , the inertia effect of particle and the coulombic force between particles should be carefully distinguished in different particle size ranges ; and proves that when droplets are weakly charged , it is still effective for the collection of sub-micron charged particles .

结果表明，在不同粒径区间内，粒子的惯性效应和雾滴与粒子间的库仑力对强化粒子靶效率的作用需要仔细加以辨认，同时证明当雾滴弱荷电时，对亚微米带电粒子捕集依然是有效的。
