A relation for the black-hole temperature in a De-Sitter type universe is determined in the
first step of this paper. As a result of that, the upper and the lower temperature limits of the black
hole are calculated, and then the limits of the radius of the universe containing the black hole. All
these calculations are based upon the present values of the cosmological constant Λ. Further
relations for the dependence of this temperature on Hubble?s constant and the gravitationsal
energy of the hardons was also derived.
