摘要

The effect of acoustic emission is used to study the acoustic radiation accompanying the combustion of flammable substances (alcohols, acetone, crude oil, and petroleum products), and experimental and calculated research results are presented. A set of time series and peak amplitude-frequency responses was formed that characterize the acoustic signals generated by these burning substances. The number of samplings recorded every 22 mu s lies in the range of 1.5. x 10(6) up to 9.7 x 10(6). Fractal R/S analysis of time series demonstrates the fundamental possibility of identifying (recognizing) the nature of a burning substance. The dependence of the Hurst index H on the nature of a substance is established, and its numerical values are obtained.
