%X Based on the discreteness of electric charge, the influences of an external magn etic filed on the persistent current of the mesoscopic coupling metallic rings a re investigated. The results obtained indicate that there is an additional pers istent current in each mesoscopic metallic ring. The additional persistent curre nts are related to the circuit parameter and coupling coefficient. If the extern al magnetic flux varies according to sine law, the effect of double_frequency an d division_frequency appears in these rings.
