This invention belongs to the field of computational chemistry of energetic materials, specifically relating to a method for evaluating the stability of substances based on the decomposition of initial bonds in the molecular crystal of energetic compounds. This method addresses the technical problems that the "bond energy method" is not applicable to molecular crystal models, and the "bond order method" cannot compare the stability of compounds laterally. By calculating the energy levels of chemical bonds within the molecular crystal of energetic compounds, this invention can both vertically compare the strength of all chemical bonds in the system to determine the initial bonds to decompose, and horizontally compare the energy levels of the initial bonds decomposed in different energetic compounds to determine the stability of the substances, thus overcoming the shortcomings of the existing "bond order method."
