【摘要】 该文系统地总结了Ｔｌ１Ｓｒ２Ｃａｎ－１ＣｕｎＯ２ｎ＋３（ｎ＝１，２，３）化合物中，Ｔｌ位元素的替代规律，讨论了替代离子的价态，离子半径对替代固溶度和超导电性的影响，并且与含Ｂａ的单Ｔｌ－Ｏ层化合物进行了对比分析．更多还原

【Abstract】 The substitutive rules of Tl sites in Tl1 Sr2Can-1O2n+3(n= 1, 2, 3)superconductors were summarized and evaluated. The effects of valency and radii of substitutive ions on substitution solubility and superconductivity were discussed, and analyses compared with single Tl-O layer compounds included Ba were coaductee.更多还原
