摘要：

The possibilities are examined of interpreting continuous acoustic emission as a sequence of fluctuations of the Poisson flow of mechanical pulses generated by elementary physical events. It is shown that the amplitude of these fluctuations may be many orders of magnitude higher than the amplitude of the pulses corresponding to the elementary events. This creates suitable conditions for the qualitatively new interpretation of continuous acoustic emission. It is mentioned that for complete characterization of continuous acoustic emission, it is necessary to give, in addition to the counting rate, the ratio between the levels of equipment noise, acoustic emission, and discrimination.
