Compared to the traditional one-by-one method,a new high-efficiency method is used to characterize large numbers of regulations varying samples.Accordingly,bump-shaped electrodes are designed using the computational fluid dynamics model,and the effect of the height and placement of these electrodes is discussed.The experimental feasibility is certified by weight loss measurement.Results indicate that flow velocities of different bump-shaped electrode surfaces are significant differences.Thus,each surface can be analyzed independently;the thickness loss of each electrode surface is consistent with that using one-by-one method,which can effectively improve the experimental efficiency 12 times.
