对聚苯乙烯粒子在电解质溶液中低频电旋转实验中观察到的科菲尔德旋转现象给出了解释。结果表明，粒子旋转的主要原因是薄双层内的电解质的电渗速度，而不是由旋转电场上的感应偶极矩的异相部分施加的扭矩。
An interpretation is given for the cofield rotation observed in low-frequency electrorotation experiments using polystyrene particles in electrolyte solution. It is shown that the main cause of the particle rotation is the electroosmotic velocity of the electrolyte inside the thin double layer, rather than the torque exerted by the rotating electric field on the out of phase part of the induced dipole moment.
