元素超导电性的新判据

本文提出一个适用于周期表全部元素的超导性判据。判据指出:一切超导元素的电负性值都在1.3至1.9之间。深入研究元素电负性与超导电性之间的关系,将有助于揭示(电子、晶格之间的)静电作用与超导电性之间的联系,这对超导机制的进一步探讨是有益的。关键词：

A NEW CRITERION FOR SUPERCONDUCTIVITY OF ELEMENTS

This article gives a new criterion for superconductivity. It can be applied to all the ele-ments in periodic table. The criterion shows that the values of electronegativity of all superconducting elements concentrate in a narrow range from 1.3 to 1.9 and that the elements with values outside this region would be non-superconductive.Deepgoing studying the relation between electronegativity and superconductivity of elements will contribute to revealing the connection between electrostatic inter action of electron with crystal lattice and superconductivity, which is able to benefit further inquiries about the mechanism of superconductivity.
