4.Intellect charge: The battery charger is using slice of flower to control charge that has constant current, constant voltage to charge, short current protection, turn lamps function and prevent to flow backward function.
9.The temperature field around the crack tip in a current-carrying plate with a penetrated arc-crack under the action of transient pulse current was calculated and analyzed using complex function analysis solution.
10.Abstract The paper gives a circuit of second band active filter ? made of secondary current transmitter, It not only is of the function ? of the voltage filter, but also the current one.
