| 摘 要： | 描述一种测量高温超导体磁通钉扎能U0及其分布的新方法,此方法主要之点是测量磁化后样品的零场临界电流随时间的变化,利用这一方法测量Tl2Ba2Ca2Cu3Oy的U0值分布(T=78K)。根据所得结果,对已报道的U0值的分散性提出一种新解释。关键词：

| Abstract: | A new method determining the distribution of flux pinning energy U0, is described. The method is mainly the measurement of time dependent zero field critical current for sintered high temperature superconductor magnetized in applied field. By means of this method, the U0 distribution of Tl2Ba2Ca2Cu3Oy at 78K is obtained. Based on the experimental result, the dispersion of reported U0 is discussed. |
