摘要：
We study suppression of superconductivity by disorder in d-wave superconductors, and predict the existence of (at least) two sequential low-temperature transitions as a function of increasing disorder: a d-wave to s-wave, and then an s-wave to metal transition, This is a universal property of the system which is independent of the sign of the interaction constant in the s-channel.
