摘要：

A temperature-dependent gap anisotropy of oxygen-annealed Bi2Sr2CaCuO8+x compound has been found in a recent photoemission experiment. The measured gap along both the high symmetry directions (Gamma-M and Gamma-X) are non-zero at lower temperatures and their ratio (of the gaps in the two directions) is strongly temperature dependent. We explain this novel feature as a natural consequence of the ''modified spin bag'' mechanism of superconductivity.
