	abstract = {Based on experimental observations we propose the small-polaron hopping model to interpret the behavior of the resistivity of PrBa2Cu3-xGaxO7-y system with x = 0.00-0.60 in a wide temperature range (14-290 K), reported by other workers. percolation arguments we evaluate the maximum hopping distances, at high and low temperatures, together with other relevant parameters, and we give a unified and meaningful explanation of the transport mechanism, for different Ga concentrations and the entire temperature range. {\textcopyright} 1994.},
