When the surface potential is large, the accelerations or decelerations of sedimentation velocity are more notable. 在高表面电位下，沉降速度受到加速或减速的情形则会更明显。
The results demonstrate that the presence of the fixed charges in the composite sphere is to slow down its settling velocity relative to that of an uncharged one. 研究结果显示，相对于不带电之复合粒子，固定电荷的存在将减缓粒子的沉降速度。
