摘　　要：我们在磁场中分别测量了最佳掺杂的YBa2Cu3O7-δ、钙0.2掺杂的Y1-xCaxBa2Cu3O7-δ及钙0.5掺杂的Pr1-xCaxBa2Cu3O7-δ薄膜的电阻温度关系.利用最近Zhang et al.[Phys.Rev.B71(2005),052502]提出的热激活能的分析方法对薄膜的磁通特性进行了分析、比较与讨论.The resistance versus temperature relations of optimally doped YBa2Cu3O7-δ thin film, Y1-xCaxBa2Cu3O7-δ thin film with x= 0.2, and Pr1-xCaxBa2Cu3O7-δ thin film with x = 0.5 were tested in magnetic fields. The data were analyzed, compared, and discussed by using the approach which recently suggested by Zhang et al. [Phys. Rev. B 71（2005）, 052502 ].
