Abstract : We investigate the behavior of maps in minimal injective resolution of an $A$-module $M$ when $\mu_t(\frak m,M)$ = 1 for some $t$, and we develop slightly the fact that a module of type 1 is Cohen-Macaulay.
Keywords : Bass numbers, minimal injective resolutions, type of modules, Cohen-Macaulay rings
