摘要：

Experimental study of boiling-up of superheated n-pentane at atmospheric pressure in a glass capillary was carried out by high-speed video. From a visual comparison of video frames, we consider the character of vaporization in three temperature ranges corresponding to the following areas of the temperature dependence of the mean lifetime of metastable state: low temperature descending section, "plateau", and boundary of attainable superheat. Temperature at the boundary of attainable superheat was about 2 degrees C lower than the maximum values reported in the literature and achieved in the more narrow capillaries and 2.5 degrees C lower than at the homogeneous boundary of attainable superheat.
