It is shown that the ratios of the quenched averaged three and four-point c
orrelation functions of the local energy density operator to the connected
ones in the random-bond Ising model approach asymptotically to some univers
al functions. We derive the explicit expressions of these universal functio
ns. Moreover it is shown that the individual logarithmic operators have not
any contribution to the connected correlation functions of the disordered
Ising model. (C) 2000 Elsevier Science B.V. All rights reserved.
