With the help of the condensed formula CaHbNcOd,formula mass(M,),initial density(ρ),standard molar enthalpy of formation(ΔfHθm),specific heat capacity(Cp),autoignition temperature(Tig),critical temperature of thermal explosion(Tb),detonation decomposition equation,expressions describing the number of moles of gaseous detonation products per gram of explosive(N),the average weight of these gases(Mg) and the chemical energy of the detonation reaction per gram of explosive(Qd=-ΔcdHθm),of C-H-N-O explosive,Kamlet-Jacobs equations of calculating the detonation velocity(D)and detonation pressure(P),and formulae of calculating the ignition enthalpy(Hi),detonation reaction energyΔfUθ,and particle velocity of detonation products(Up,d),the values of standard internal energy of formationΔfEθ,detonation reaction energyΔfUθpolytropic exponent k,ignition enthalpy Hi,D,P and up,d of 16 explosives C-H-N-O explosive of evaluating the energy and damage effect of explosives were obtained.
