We continue our investigation of nonequilibrium statistical mechanics in which irreversibility comes out from contractions of microscopic informations about amacroscopic system. The hypothesis advanced by Machlup and Onsager that an extended entropy depends upon the fluxes is examined by applying the time-smoothingprocedure proposed by the present author. Starting from this hypothesis and by usingthe previous method, the expressions for these fluxes are given. It is necessary toassume that an initially time-smoothed density matrix depends upon a particular setof dynamical operators A, and A,= (iH, .4,1. The fluctuation-dissipation theorem isalso discussed.
