双极的

The term AC electrokinetics refers to the movement of particles using AC electric fields. An AC field induces a frequency-dependent dipole on a polarizable particle. The interaction of this dipole and a non-uniform field can give rise to dielectrophoresis.

根据电动力学理论，当施加一交流电场时，可使其中可极化粒子产生出一与频率相关的电双极，藉由与周围介质在非均匀电场下交互作用，可产生介电泳现象。

Some electrophysiological index were measured, including atrial effective refractory period, rate adaptability, dispersion of AERP, inducibility and duration of induced atrial fibrillation under different basic pacing cycle length (300, 250 and 200 ms). Results: Contrast with control group, the values of AERP at 6 sites were shortened and maladaptation.
