Toexploretheinfluenceoftheafter-burningonthestrengthoftheshockwavesproducedby thethermobaricexplosiveexplosioninair,experimentsandnumericalsimulationswereperformedto investigatetheenergyoutputstructure.Theresultsshowthattherelietwopeaksonthepressuretimecurvesinthenearfieldandalongpositivepressureperiodinthefarfield.
