چکیده
This paper theoretically substantiates research into the spectral features of dynamics main dangerous parameters a gas environment when igniting materials in laboratory chamber. Studying such is based on calculation direct discrete Fourier transform for measurements, equal number, over current intervals observation hazardous examined parameter medium before and after material ignited. In this approach, makes it possible to determine instantaneous amplitude phase spectra time under consideration. explore peculiarities distribution amplitudes phases harmonic components spectrum ignition materials. The results experimental studies established that nature low-informative not sensitive enough fires. contribution investigated chamber made by frequency range 0–0.2 Hz. 0.2 Hz insignificant decreases with increasing frequency. It from spectrum, random scattering exceeding informative. was found spread these depends type material. reported here could prove useful devising new effective technologies detecting fires premises objects various fields protect against explained fact detection premises, high-frequency are important, characterized increase
