Summary

LARGE HEAT PULSE TRANSFER FROM FILM HEATER INTO HELIUM AT BATH TEMPERATURE 1.7-3 K IS CONSIDERED. EXPERIMENTS WERE CARRIED OUT AT VAPORIZATION ONSET AND AT THE FILM HEATER TEMPERATURE IN HELIUM I AND HELIUM II. THE PRESENCE OF NONEQUILIBRIUM LAYER ACCOUNTS FOR NO DIFFERENCE IN THE MECHANISMS OF HEATING UP TO THE VAPORIZATION ONSET OF HELIUM I AND HELIUM II IN THE MEASUREMENTS. THE CRITICAL PROCESSES LOCALIZED NEAR THE HEATER ARE NOTED TO BE DEVELOPED AFTER THE VAPORIZATION ONSET OF HELIUM.
