摘要：

We generalize the two-dimensional d wave model for high T-c superconductors to describe cases with a small structural anisotropy within the layers, yielding a ''d + s'' wave pairing. This model should be more appropriate for orthorhombic cuprates if the d wave model correctly describes the tetragonal ones.
