摘 要:
最近发现的金属间化合物MgB2是具有很高转变温度的超导体，提出的一种各向异性s-波超导体模型，它能够很好地描述这种化合物的性质，包括热力学性质和光学响应性质。也确定了准粒子态密度的形状、上临界磁场和超流密度的各向异性。[著者文摘]

Abstract:
It has recently been observed that MgB2 is a superconductor with a high transition temperature. Here the authors propose a model of anisotropic s - wave superconductivity which consistently describes the observed properties of this compound, including the thermodynamic and optical response in sintered MgB2 wires, The authors also determine the shape of the quasiparticle density of states and the anisotropy of the upper critical field and the superfluid density.[著者文摘]
