The proof of identification of the location of horizons determined both by Damour-Ruffini-Zhao's (D-R-Z) method and by equation of null super-surface is given. The formula of temperature on the horizon for general black holes is obtained and is successfully checked by a variety of models of black holes.12 pages, LaTeX, no figuresGeneral Relativity and Quantum Cosmologytext
