(Received October 5, 1974)
The previous formalism for dealing with the average effect of a highly supersonic turbulent gravito-hydrodynamic field in the hadron era of the universe is extended so as to take into consideration various dissipative processes in the hadronic substratum. After a phenomenological fixation of the coefficients of bulk viscosity, shear viscosity and heat conduction, it is shown that those dissipative processes have a considerable influence upon the three characteristic mean-value quantities (at the bounce epoch of our regular model-universe) corresponding to metric, velocity and density fluctuations. A possibility of fixing the dissipation coefficients of the hadronic matter under consideration, i.e., the one based on the concept of statistical bootstrap, in a more well-founded manner is also conjectured.
