Methodology of estimation of education is worked out in an emulsive explosive (ЭВВ) sensibilized easy малопрочными high-porous granules, coherent "granule-air system". The structure of ЭВВ in this case appears as "fog" from the drops of matrix emulsion, that divide from each other the air including and (or) indicated granules. It is shown that formation of this structure in ЭВВ results in changing mechanism of excitation of detonation in this explosive. Excitation of detonation begins to take place under the action of high-enthalpy gas stream filter-passing from an area high-pressure of zone of chemical reaction in a detonation wave. Thus a chemical reaction takes place in form the superficial burning of particles of emulsion, co-operating with the stream of gas. A detonation process acquires stream character. Analytical criteria are got for the estimation of terms of origin and steady distribution of stream detonation.
