摘要：

Samples of Bi2Sr2Ca1-xPrxCu2Oy have been characterized by resistivity and thermoelectric power measurements. All metallic samples show superconductivity with a maximum T-c=90 K at x=0.2. The sample of x=0.6 shows a crossover from hopping conduction at low temperature above T-c to metallic conduction at high temperature. For the metallic samples below x=0.6, the results of thermoelectric power are well fitted by both of a phenomenological band spectrum model and the Nagaosa and Lee model.
