摘　　要：在８０—１２０Ｋ温区内测量了（ＢｉＰｂ）２Ｓｒ２Ｃａ２Ｃｕ２Ｏｙ、（ＢｉＰｂ）２Ｓｒ２Ｃａ２Ｃｕ３ＯｙＦｘ样品在混合态下的Ｓｅｅｂｅｃｋ效应，结果表明，与传统超导体不同，磁通线的运动并不是引起高温超导体磁场下Ｓｅｅｂｅｃｋ效应的唯一因素，样品掺Ｆ可改变磁通钉扎状态．Abstract The Seebeck effect of (BiPb)2Sr2Ca2Cu3Oy. (BiPb)2Sr2Ca2Cu3Oy, Fx samples was measured in the mixed state between the temperature range 80K to 120K. The results indicate that for high temperature superconductor, unlike tradition al superconductors, flux is not the only reason of Seebeck effect under magnetic field. The flux pinning state is influenced by the dopping of F.
