  The results of the investigation of changes of parameters of dynamic bipolar
charge-voltage and bipolar and unipolar dynamic current-voltage characteristics
and transient currents connected with the pulse change of humidity for the
samples of por-Si are presented. The view of high voltage current-voltage
curves is characteristic for poling processes in the space charge region
similar to that observed in the case of typical ionic conductors. Observed
phases of transformation of investigated electrophysical characteristics
reflect the time scale of processes in the consequence adsorption-dissociation
and transfer - desorption. The efficiency of using the methods of dynamic
electrophysical characterization for studying characteristics of porous
materials under fast humidity changes was demonstrated.
