The intermittentcurrent device has been employed in the electric circuit so that the control of the polishing condition becomes more feasible.
电路中采用了间歇电流装置，使抛光条件更易于控制。

It and reversing current different is not to be, but with a anode intermittently stop, because the intermittent power supply current interrupted, cathode potential with time periodically change.
Contact mark. Intermittent marks adjacent to the weld line resulting from the electrical contact between the electrodes supplying the welding current and the pipe surface.
