测量了Ｔｌ系２２２３相银包套超导带（Ｊ＿ｃ＝１．５×１０￣４Ａ＊ｃｍ￣（－２），７７Ｋ，０Ｔ）在０－０．８Ｔ磁场下电阻转变展宽，实验结果引用热激活磁通蠕动模型加以解释。磁场平行于带面（Ｈａｂ面）和磁场垂直于带面（ＨＪ⊥ａｂ面）两种情况下，激活能与磁场之间满足幂指数关系：Ｕ＿（０）＝０．２１，其中Ｈ的单位为ｋＧ。对Ｈａｂ面，ＨＩ时出现的与宏观洛仑兹力无关的耗散进行了讨论。
The resistive transition broadening of Tl series 2223 silver coated superconducting tape (J_c = 1.5 × 10 ~ 4A * cm ~ (-2), 77K, 0T) was measured at 0-0.8T magnetic field. Activate the flux creep model to explain. When the magnetic field is parallel to the Hab plane and the magnetic field is perpendicular to the HJ⊥ab plane, the exponential relationship between the activation energy and the magnetic field satisfies the following formula: U_ (0) = 0.21, where the unit of H For kG Dissipation related to the macroscopic Lorentz force that appears in the Hab plane and HI is discussed.
