本文研究了La替代Pr对T′相Pr 2-yLay-xCexCuO_（4-δ）超导电性和电阻率的影响。对于大量的La取代样品的1.0 y 1.2，超导体的体积出现在较小的x值的范围内，0.10 x\lesssim0.15。这是讨论中的电阻率和载流子浓度的CuO 2片。
Effects of the La substitution for Pr on the superconductivity and the electrical resistivity have been investigated in Pr2-yLay-xCexCuO4-δ of the T′-phase. For heavily La-substituted samples of 1.0≦y≦1.2, superconductivity of the bulk appears in the range of smaller x values, 0.10≦x\lesssim0.15. This is discussed in relation to the electrical resistivity and the carrier concentration in the CuO2 sheet.
