摘要：

It is proposed that the temperature dependence of the superconducting gap Delta(T) in high-T-c cuprates can be predicted just from the knowledge of Delta(0) and the critical temperature T-c, and, in particular, Delta(0)/T-c > 4 implies that Delta(T-c)not equal 0, while Delta(0)/T-c <= 4 corresponds to Delta(T-c)=0. A number of tunneling experiments appear to support the above proposition, and, furthermore, show reasonable quantitative agreement with a model based on the two-dimensional stripe hypothesis.
