Local fluctuations of physicochemical parameters in condensed system combustion

Using the 3Zr + 2WO$_3$ system as an example, it is shown that fluctuations of physicochemical parameters in the combustion wave of a condensed system in both loose and pressed forms can be recorded by means of two parallel wires placed in the burning system. It is established that changes in the initial density of the system and its burning rate results in corresponding changes in the fluctuation frequency. The relationship between these three parameters can be expressed, as a first approximation, by a fairly simple analytical relation.
