摘要：

Humidity response characteristics of BaTiO3 doped with lanthanum were examined using complex impedance measurements. A sample with relative density of 71 % showed a nearly log-linear increase of conductivity with humidity at 118 Hz. The average capacitance of bulk changed little with humidity; however, the resistance showed a gradual decrease. The equivalent circuit explaining such an observation was presented.
