abstract = {Let    S be a commutative Noetherian ring and        a   a proper ideal of    S. We give several bounds of        a  -depth of    S-complexes and    S-modules, investigate the behavior of        a  -depth and        a  -Cohen-Macaulay modules under tensor product with a faithfully flat    S-module. Furthermore, we establish the Foxby equivalence of        a  -Cohen-Macaulay    S-modules.}
