    摘要: A connector for a circuit board has a pins that are compatible with a standard ISA connector. The connector includes at least 38 pins connected to a ground potential, at least 23 pins connected to a VCC potential, and a plurality of bus select pins, through which the circuit board can select a particular bus. Over the selected bus, communications are transmitted to and from the circuit board.

    摘要: Magnetic ion-exchange polymer microspheres and a method for preparing the same are provided. The method for preparing the magnetic ion-exchange polymer microspheres includes swelling the ion-exchange resins and allowing the magnetic nano-particles to enter the interior of the ion-exchange resins. The magnetic ion-exchange resins of the present invention have various functional groups can be introduced onto the surfaces thereof. Therefore, the magnetic ion-exchange resins of the present invention can be applied in many areas, and thereby they have high economic value.
