Determination of the internal ionic resistance of porous electrodes;

Potential step chronocoulometry and current step chronopotentiometry are used to determine the real surface areas of the porous electrodes,the compensation resistance of the electrolyte,the internal ionic resistance of the porous electrodes and the time of transition.

This paper gives complete analysis on the reasons which caused oscillation and miss of synchronization of stepping electromotors, and introduces five electronic damping methods about how to avoid oscillation.

It was noticed that the increased damping of structures by means of electronic damping techniques, a kind of velocity feedback closed loop with piezoceramic wafers as actuators and sensors, was rather limited.
