【Abstract】 The principle on fast and slow capacitive transient currents and its mechanism were produced; the methods of canceling them were described. Under the procedure controlled, an iterative algorithm was adopted to compensate fast and slow capacitive transient currents automatically. The experimental result showed that this method could compensate the capacitive currents quickly and effectively. The application of the method would save operation time and improve the efficiency of experiments.更多还原
