Abstract: Based on the analyses of combustion heat in the field of engineering combustion. We further clarified and standardized the concept of "explorsive heat" in the field of the solid propellant combustion study. In order to provide some suggestions for the standardization and improvement of the terminology in the domain of the energetic materials combustion engineering such as fire blasting explosive and the solid propellant,we proposed a new concept "Semi-Explorsive Heat"

Key words: heat, combustion, explosion, semi-explosion, energetic materials
