The forming process of AC electroosmosis (AC EO) flow was explained during exploring the mechanism of electro polarization. With building the equivalent circuit and theoretical model of asymmetry microelectrodes, the calculation formula of the time- average velocity of AC EO mi-cropump was gained and through analysis it explained symmetrical microelectrodes can produce local electroosmosis flow but its time-average velocity is zero, which offers the theoretical basis for futher analyzing and researching AC electroosmosis micropump.
