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.
有人提出，高温铜酸盐中超导能隙Δ(T)的温度依赖性仅根据Δ(0)和临界温度T(c)就能预测，特别是，Δ(0)/T(c)>4意味着Δ(T(c))≠0，而Δ(0)/T(c)≤4则对应于Δ(T(c)) = 0。一些隧道实验似乎支持上述观点，此外，还与基于二维条纹假设的模型在定量上表现出合理的一致性。
