  We show that superconductors with inhomogeneous order parameters can show
similar features as anisotropic ones. In this paper we study the low
temperature specific heat dependence in such a system and we show that the
disorder associated with randomly distributed attractive centers convert the
BCS temperature exponential behaviour into a power law formula. To describe
superconductivity we used a random version of the negative U Hubbard model,
while the disorder was treated by means of the Coherent Potential Approximation
(CPA).
