传统的费米液体超导电性理论预言，具有各向异性配对的超导体对表面散射反应敏感。结果，表面被一层厚度为几个相干长度的强畸变超导层所覆盖，其性质与体材料不同。
The traditional theory of superconductivity in Fermi liq-uids predicts that superconductors with anisotropic pairingshould react sensitively to surface scattering. As a result,surfaces are expected to be covered by a layer of thicknessof a few coherence lengths of strongly distorted supercon-ductivity with properties different from those of the bulk.These anomalous surface phenomena were first discussedin the context of
